After a disappointing docent hiking tour by the National Wildlife Federation and Cougar Conservancy of the Wallis Annenberg Wildlife Crossing event I decided to find a hike to actually see the wildlife crossing. You can hike from only the south side. Ignore the north route I drew above. The south has a cleared hiking trail all the time. The north side has no view point at all. I hiked it personally and you can't see the crossing from that side because of a ridge. You can see it by walking on the side of the freeway on the north side but that's illegal.
South side hike is 1,300 feet up a hill on a cleared hiking trail. GPS start 34.136984400411855, -118.72892708553738 GPS end 34.13617430519416, -118.73339603254912 . You park on the road which is 27571 Agoura Rd, Agoura Hills, California 91301. There are signs there showing you the hike. There are two great view sites just 100 ft up the trail. It's called Abrams Trailhead on the map. No need to go to the top. Unfortunately you can only see the two side retaining walls and the top of the middle platform from the south side.

NORTH SIDE
The culverts are the ones used by P22 and other mountain lions to cross the freeways. Bring sun protection, water, wear tall boots, long pants, long shirt so you don't have to worry as much about ticks and brush. No sandals, open toed shoes or shorts. Don't walk on the freeway because it's illegal. Here are live cams so you can see current temperature, clearing.

P22 mountain lion necropsy report final and full.This is the result of a state information act I made immediately after P22 was euthanized. There are a lot more documents I'm downloading now so check back. There are also a lot of trail cam and security cam videos. Below is one of P22 washing his face.
Here's another video of P22 with a raccoon. Video is not gross though he probably killed and ate it later.
Mountain Lion from the LA area, P-22. Age estimated around 12 years old. Free-ranging but was losing body condition, changing behavior. Immobilized in the field by CDFW and brought to LA Zoo for diagnostics. Then brought to Safari Park for further evaluation. CT and various other diagnostic testing
revealed diaphragmatic hernia with herniated liver parenchyma and omentum. Renal insufficiency also suspected, along with possible myocardial disease.
Diffuse ectoparasitism with Demodex gatoi also identified. Euthanasia was pursued at the decision of CDFW, and was performed with IV pentobarbital.
After euthanasia, testicles were removed for gamete recovery.

Received is a 44 kg, adult male mountain lion (puma) in fresh postmortem and good to fair body condition with mild generalized muscle atrophy and small to
moderate fat stores. There is patchy alopecia and poor hair coat along the ventral neck, face, ears, distal tail (distal 25 cm), and distal limbs and feet. Two
black, hairless, soft, pedunculated skin nodules are present on the dorsal neck which are 2 x 1.3 x 1.2 cm and 1 x 0.9 x 0.4 cm. A 3.6 x 1.7 cm area of
alopecia caudal to the right eye also has 2 scabs. The right eye has patchy hemorrhage in the dorsal sclera and conjunctiva, and areas of redness overlying
the lateral aspect of the iris within the eye. A small scab is present on the skin over the dorsal aspect of the left eye orbit. Along the right ventral mandible is
a 2 x 0.6 cm crusted ulceration with edema and tan discoloration of the underlying subcutis. Areas of alopecia (~5 x 2 cm) are present over both hips, and
there is a 1 x 0.8 cm abrasion along the lateral metatarsal region of the right hindfoot. Multiple claws are frayed. There is a 0.5 cm diameter skin incision
along the left medial aspect of the stifle (antemortem skin biopsy). Within the right frontal sinus is a small amount of brown clotted blood. The zygomatic
process of the right frontal bone surrounding the right ocular orbit has multiple chip fractures with mild associated hemorrhage.
There is mild hemorrhage in the subcutis and muscle along the lateral aspect of the right shoulder and proximal humerus. Some hemorrhage is also present
around the left jugular venipuncture site in the neck. Fractures of the transverse process of the 7th cervical vertebra and acromion process of the right
scapula noted on CT scan are not readily identified grossly. A thin (<1 mm diameter), approximately 2.5 cm long silver metallic wire foreign body is
embedded along the internal aspect of the caudoventral abdominal midline. The reported metallic pellet in the region of the left hip on CT scan is not found.
Negative pressure is absent in the thorax on opening the abdominal cavity. The lungs are diffusely collapsed and pink. The heart is 218.9 g (0.498% of body
weight), and the mitral valve leaflets are mildly thickened and smoothly nodular. There is a 3 x 2.5 cm hole in the right ventral aspect of the diaphragm
through which a portion of omentum (approximately half) is herniated into the right thoracic cavity. The margin of this diaphragmatic tear is smooth and
rounded with no evidence of hemorrhage. An approximately 1 cm diameter dark red nodule also bulges into this tear which is adjacent to a second
approximately 5 cm diameter tear centrally in the diaphragm. This tear also has smooth edges, and through it bulges into the thoracic cavity a roughly 9 cm
diameter x 4 cm thick section of liver which is discolored and mottled shades of tan, orange and red. There are tight adhesions between the left crus of the
diaphragm and the left lateral lobe of the liver. Pleura and connective tissue is tightly adhered to and encapsulates the intrathoracic herniated portion of liver,
which appears to be a portion of the left medial lobe or papillary process of the caudate lobe. The cystic duct of the gallbladder is sigmoid in shape. The liver
is 1.4 kg (3.2% of body weight), subjectively enlarged with rounded lobe margins, and is diffusely dark tan with a moderately enhanced reticular pattern.
A perihepatic lymph node is mildly enlarged at 7 x 1.5 x 0.7 cm, and the mesenteric lymph nodes are similarly prominent. The spleen is diffusely enlarged,
dark red, and congested (presumed euthanasia artifact). The medullae of both kidneys have mild pale tan streaking to the renal crests. Numerous long
cestodes are present throughout the small intestine. In the dorsal peripheral aspect of the left thyroid gland is a soft, brown, 0.9 x 0.8 x 0.7 cystic nodule
filled with brown cloudy fluid.

Final Summary
Final Summary
The many lesions identified in this wild mountain lion on postmortem examination are consistent with the extensive clinical work up, history of recent and
previous trauma, and reported deteriorating condition. Supporting the diagnosis of recent trauma (hit by car 6 days prior to euthanasia) was the histologic
appearance of the right orbital fracture and gross evidence of hemorrhage in the adjacent frontal sinus and right eye. The suspected intraocular hemorrhage
was not present in the examined histologic section of this eye, however, which appeared within normal limits. An inflamed tract/wound along the right
mandible could also have been related to this traumatic event, though it could also have been more chronic. The diaphragmatic tears, through which
omentum and a portion of liver were herniated into the thoracic cavity, appeared to be of much longer duration with smooth margins, mature fibrous
adhesions, and chronic changes in the affected liver lobe. These were presumably the result of previous trauma, the exact timing of which cannot be
determined from the gross or histologic appearance. Although there was evidence of a degree of chronic vascular compromise to the herniated lobe, the
remaining majority of the liver was unaffected and relatively normal histologically.
A presumed major contributor to the deteriorating condition was skin disease. Heavy colonization of hair follicles with dermatophytes and Demodex sp.
mites was seen in all examined sections of skin (face, neck, hip, foot). These combined infections account for the poor condition of the hair coat and
probably some of the systemic inflammatory response evident in the bloodwork and histologically as myeloid hyperplasia and circulating neutrophilia. The
intrafollicular location of the Demodex mites is more consistent with D. cati or the third feline Demodex sp. as opposed to D. gatoi, which colonizes the
stratum corneum. Generalized D. cati infections suggest underlying immunosuppression or other disease. A Microsporum canis species was identified from
antemortem hair samples and is consistent with the fungal/dermatophyte lesions seen, which included both extensive hair colonization and rare microscopic
pseudomycetomas in skin, tonsil, and axillary lymph node. The latter finding is interesting evidence of lymphatic spread of the M. canis infection beyond the
skin, although the lesions were few and small.
Consistent with the advancing age of this animal, there were a variety of relatively mild, non-specific, age-related changes, including valvular endocardiosis,
arteriosclerosis, and renal disease. The renal changes seen primarily involved glomeruli and could be related to chronic inflammation (such as from the skin
disease) or cardiovascular disease, such as hypertension. Glomerular injury accounts for the reported proteinuria. Findings of undetermined cause and
significance included regional gastritis and a small pulmonary venous thrombus. The gastric inflammation involved the pylorus (or possibly the cardia) and
was neutrophilic and damaging to the glands, some of which contained Helicobacter-type spiral bacteria. No other parasites were seen in the stomach. A
specific cause was therefore not identified, but recent stress and Helicobacter could have been involved. In the small intestine, moderate numbers of
cestodes were probably incidental.
Toxicologic analysis of a liver sample for rodenticides (performed by CAHFS) found 5 anticoagulant rodenticides at varying concentrations as well as a trace
amount of bromethalin. Despite exposure to multiple compounds, two at relatively high levels (diphacinone and bromadiolone), there was no evidence of
abnormal hemorrhage that would suggest a coagulopathy due to toxicosis. Bromethalin does not typically result in histologic lesions, but no clinical
(neurologic) signs of bromethalin toxicosis were reported antemortem.
I support humane legal petting zoos and farm sanctuaries because it exposes people to farm animals in a caring pet like manner. When children see and pet farm animals they are more likely to care about them and their welfare. If they pet them like they do a cat or dog, they will grow up caring more about them. They may even put two and two together and realize hamburgers, hotdogs are cows and pigs. Chicken is a real live chicken. Eggs come out of chickens. Milk comes out of cows. Eventually they may not want to eat them which is better for their health, environment and the animals.
I went to a petting zoo when I was maybe five or six. I pet chickens, cows, pigs and had a great time. Then I went to lunch with my Nana. When we were ordering food it finally clicked. Chicken on the menu was the cute live chicken I just pet at the petting zoo. I asked my Nana if "chicken" was actually the animal chicken. She said "yes." She also told me that hamburgers were cows and hotdogs were pigs. I was soooooo grossed out. I said I didn't want to eat my friends. She was fine with that so I ate rice and beans which is what we ate at home. Eventually I learned about eggs and didn't want those either. Same with milk.
I also support humane and legal farm sanctuaries. The thing about farm sanctuaries is you are basically preaching to the choir unless it's a school field trip. People who go to farm sanctuaries are generally already vegan. You aren't necessarily educating non-vegans who most need the exposure and education. Petting zoos are at fairs, events, road sides, farmers markets where families have easy access. They're generally also free. You just pay for animal feed. Most farm sanctuaries are on agriculturally zoned land far out of cities and towns. I personally think a farm sanctuary should offer petting zoos to some major county fairs. They'd get more exposure and more animals can be saved or at least treated better.
When children are with animals including farm animals they learn respect, compassion and empathy for animals. If they pet or brush them, they learn to care for and about them. Children experience sensory development, motor skills development, language development and learn social skills. There is a lot of research which shows the benefits of animals for children. All of these benefits also benefit animals because children end up caring more about them.
I don't support illegal inhumane unpermitted petting zoos. You need a USDA exhibit permit for a petting zoo. You also need a city and county permit from animal control. There are regulations no matter what lies an ill informed activist tells you. There are USDA and other animal regulations that cover petting zoo and animals. They are covered by federal, state and local animal abuse, neglect, and cruelty statutes.
Petting zoo animals are not for consumption. They are not food animals because they most likely have received medications over their life span. They will also be injected with euthanasia drugs when they are dying which makes it illegal to use them for food. Animals must be cared for legally and properly. I want children and others to see healthy farm animals who are well cared for and treated. I want people to realize they are living, breathing, sentient beings and not just fried chicken, hamburgers and hotdogs.
A humane petting zoo or farm sanctuary limits the number of children in the pen at one time. They also limit the time each animal is in the pen. Some animals love being pet and some don't. Clearly they should only use animals that enjoy it. That's why there are mainly goats and sheep. Bunnies are too sensitive and shouldn't be in petting zoos. Chickens could be in another pen with more protection. There must be sun protection and protection from heat, cold, rain, weather. There must be adequate food and water available.
There should be proper hand washing stations and instructions so zoonotic diseases aren't spread. That is the law which is generally enforced by the State Agricultural Department and County Health Departments. If the zoo is at a fair, there are other regulations. If it's in a farmer's market, there are even more regulations. If they sell food in the area, there are even more regulations. There are generally a few people inside the pen to enforce all the regulations.
Petting zoos have their own regulations such as no picking up animals, no chasing, no pulling, no hitting, no riding, no running, no screaming... Parents must be in there with their children. Children under certain ages aren't allowed for health reasons. No food or drink in the pen except the animal feed. No smoking, toys, pacifiers, strollers, baby bottles, weapons, alcohol... No touching the animals food or water. The zookeepers don't want their animals stressed or harmed. It's their business and they generally really care about their animal if it's a humane zoo.

July 15-23, 2023 is Latino Conservation Week. Enjoying and Conserving our Earth, Disfrutando y Conservando Nuestra Tierra is an initiative of the Hispanic Access Foundation. Latino Conservation Week was created in 2014 to support the Latino community getting into the outdoors and participating in activities to protect our natural resources.
During this week, community, non-profit, faith-based, and government organizations and agencies hold events throughout the country. From hiking and camping to community roundtables and film screenings, these activities promote conservation efforts in their community, and provide an opportunity for Latinos to show their support for permanently protecting our land, water, and air.
Animal Advocates is participating in Latino Conservation Week joining Latinos across the nation to support the protection of our natural resources. We continue to conserve nature by educating the public about wildlife and rescuing ill, injured and orphaned native wildlife for release back to the wild. Animal Advocates was founded by Latina Mary Rivera Cummins in 2002 over 20 years ago.

You've probably all heard the story about Vanilla the 28 year old chimp seeing the sky "for the first time in her life" at Save the Chimps.That's not true. She was raised at a breeders then sold to a lab. She lived in the lab for less than a year. In 1995 when she was one year old she was sent to exotic animal rescue
Wildlife Waystation here in California. There was no solid secure roof originally which is against USDA and Fish & Wildlife regulations. Some of the chimps escaped so they were forced to add a secure roof. It wasn't all a solid roof. It was also chain link just like the sides. The chimps could see the sky through the roof and sides, see photo below. It was actually a pretty large enclosure. This is just an upper loft area.
Vanilla the chimp is most likely just in awe she could see the sky again after being in quarantine for six months indoors. She looks like me after I've been inside for a couple of days working and I go outside and see a beautiful day. The article also forgets that Vanilla is still in captivity.
A lot of these places make up stories to go viral to get mega donations. This place already raised $4,000,000 just to take the Wildlife Waystation chimps, https://ktla.com/news/local-news/last-of-the-stranded-wildlife-waystation-chimpanzees-finally-relocated/ . They refused to take the chimps unless they were given millions of dollars. Martine Colette did the same when she first took the 32 chimps from the lab. Now they make another story to get more donations. They have a board, employees to be paid so they need to raise massive amounts of money. In the end animals are saved so that's all that really matters. Still, the truth would be nice.
"Vanilla, a 28-year-old chimpanzee, has lived her entire life in captivity without an unobscured view of the sky. But now, a heartwarming new video shows the great ape seeing the sky for the first time at an island chimp sanctuary in Florida.
For a portion of her early life, Vanilla lived inside a New York biomedical research facility, where she and dozens of other chimps (Pan troglodytes) were housed in small cages "suspended from the ground like bird cages," according to a statement from Save the Chimps, a sanctuary in Fort Pierce, Florida, that rescued her and 29 of her peers.
After being removed from the New York facility in 1995, Vanilla and other captive chimps were shipped to the Wildlife Waystation, an animal rescue facility in California that shuttered in 2019, where she was boxed inside a roofed enclosure, cut off from the outside world, according to the Daily Mail."
Mountain Lion P22 Killed by Poison, p22, p-22, puma,mountain lion,cougar,mary cummins,animal advocates, animaladvocates.us, marycummins.com, wildlife rehabilitation, los angeles, caliornia, fish, game, poison, anticoagulant, griffith park
Los Angeles' most famous mountain lion P-22 was euthanized by the California Department of Fish & Wildlife December 17, 2022 due to fatal injury and illness. The necropsy report (https://wildlife.ca.gov/News/final-necropsy-results-released-for-mountain-lion-p-22) was released June 14, 2023. It showed his death was caused by exposure to anticoagulant poison and traumatic injury.
The report stated he suffered "recent trauma to his head and right eye, including an orbital fracture." He had "older, significant trauma, including a diaphragmatic rupture, through which the liver and sections of connective tissue from the abdomen had herniated and were inside his chest cavity." The injuries were most likely from a car strike.
He was "underweight, arthritic and had progressive and incurable kidney disease." He had "a severe parasitic skin infection over his entire body, caused by demodectic mange and a fungus, specifically ringworm." Toxicology "revealed exposure to five anticoagulant rodenticides compounds."
Research has shown that long term exposure to anticoagulant poison causes the immune system to be suppressed. The body is no longer able to fight off common parasitic infections such as mites and ringworm. The poison also causes anticoagulant-related nephropathy and results in bleeding in the kidneys which causes kidney failure. Over time the animal becomes weak, dehydrated and unable to easily procure prey animals. This causes the animals to more easily be hit by cars. Poison ultimately killed P-22.
All of the bobcats, foxes, coyotes that we've taken into our wildlife rehabilitation facility over the last 20 years that were hit by cars had major mange mite infestations. They were thin, weak, dehydrated and had poor coat condition just like P22. This was caused by the animals eating poisoned animals. Poisoned animals are easier to catch than healthy ones. People use anticoagulant poison to kill ground squirrels, gophers and rats around homes, golf courses and parks. You can clearly see the poison bait stations scattered all around Griffith Park where P-22 lived. We've taken in many poisoned animals from this park.
The main causes of mountain lion deaths are depredation permits, poison and auto collisions. A depredation permit is a permit to kill a specific mountain lion after they have injured or killed someone's pet or farm animal. The owner of the dead animal requests the permit and a hunter shoots it dead. Some estimate there were or are about 4,000 mountain lions in California. From 2001 to 2018 1,400 were killed by depredation permits per Fish & Wildlife.
The other main cause of death is poison. 96% of mountain lions that have been tested have been exposed to anticoagulant poison per Fish & Wildlife. They are poisoned for their entire lives if they live near human development. This causes kidney failure besides many other health issues similar to what P22 suffered. Poisoned animals are more likely to be hit by cars.
Fish & Wildlife has tried to limit the poisoning but failed because pesticides are not under their jurisdiction. Depredation permits are under their jurisdiction. We need state politicians to step up and call for an emergency injunction to all depredation permits. There also must be tougher restrictions on the use of anticoagulant poison outdoors where non-target wildlife can be poisoned. I've witnessed coyotes sitting right outside poison stations in Griffith Park waiting for the animals to exit so they can eat them.
While wildlife crossings will help some wildlife it may cause others to encroach deeper into developed parts of the city increasing their risk of being killed by depredation permits, poisoning and car strikes. One can only hope our local mountain lions use them to exit the city instead of entering. We owe it to P22 and all of Los Angeles' wildlife to do better. For years people have complained about poison and depredation permits yet nothing has changed. Maybe P22's cruel and agonizing death will be the impetus Los Angeles needs to finally change things.
Mountain lion P-22 died from being hit by a car and poison, california department of fish and game, mary cummins, animal advocates, griffith park, los angeles, california, car, death,died, necropsy, autopsy, puma, cougar, wildlife
The California Department of Fish & Wildlife finally released the necropsy report for Griffith Park mountain lion P-22 who died December 17, 2022. He died as a result of being hit by a car and long term poisoning. He had five different types of anticoagulant poison in his liver, blood and fat. Research has shown that poison causes permanent organ damage especially to the kidneys. Anticoagulants cause serious kidney damage called anticoagulant-related nephropathy (ARN) and results from bleeding in the kidneys. Poison also causes immunosuppression which causes the body to not be able to defend itself from common mites and other conditions. The poison caused P22 to become ill and weak which is most likely why he came closer to humans looking for easier prey. When they become lethargic from the poison they are more easily hit by cars. Poison killed P-22. We must stop poisoning wildlife. Poison and depredation permits cause 100x more mountain lion deaths than cars.
In July of 2011, the California Department of Fish and Wildlife requested California Department of Pesticide Regulation (CDPR) restrict the use of anticoagulant rodenticides due to numerous incidents involving direct and indirect poisoning of wildlife. Nothing was done. They requested the same in 1999. While CDFW has no jurisdiction over pesticides they do control depredation permits for mountain lions. In light of the many deaths from poison no new depredation permits should be allowed. An emergency injunction is needed. 1,700 mountain lions have been killed in California with depredation permits from 2001 to 2018. Population estimates were 4,000 total in California. 42% were killed by people who were not willing to protect their pets or farm animals with proper barns or fencing.
We did a State Information Act Request to the California Department of Fish & Wildlife for the necropsy report immediately after P22's death. They repeatedly stalled and stalled stating it was a lot of information to compile and would take more time than allowed by the law. The report was finished within days of P22's death. We've had wildlife necropsied at the same state lab that did P22's toxicology report. It takes a few days max. Immediately after finally writing up a lawsuit to compel production of the information act request they department released the report publicly.
California Department of Fish & Wildlife Press Release About P-22 Necropsy Report
The California Department of Fish and Wildlife (CDFW) and National Park Service (NPS) reviewed the final postmortem examination and lab tests from P-22, the beloved mountain lion from Griffith Park. The results confirmed P-22 had been suffering from multiple severe injuries and chronic conditions that impaired his ability to function in the wild and would have lowered his quality of life if placed in human care.
P-22 was captured and anesthetized by CDFW and NPS on December 12, 2022, after scientists noted a recent change in his behavior.
He was transported to the Los Angeles Zoo for initial examination and treatment, then transferred to the San Diego Zoo Safari Park for follow-up evaluation, including a computed tomography (CT) scan, where it was discovered that he had serious injuries and health problems. He was euthanized under general anesthesia on December 17, 2022.
The postmortem examination was completed by veterinary pathologists at the San Diego Zoo.
"We are grateful to the San Diego Zoo Safari Park and Los Angeles Zoo teams," said Deana Clifford, a senior wildlife veterinarian for CDFW. "They provided excellent care for P-22 and conducted a detailed postmortem examination that shed plenty of light on this cat's condition."
Some findings demonstrated that P-22 had recent trauma to his head and right eye, including an orbital fracture with bleeding and early stages of scar tissue development. This is consistent with reports of a vehicle strike the night before he was captured.
P-22 also had injuries consistent with older, significant trauma, including a diaphragmatic rupture, through which the liver and sections of connective tissue from the abdomen had herniated and were inside his chest cavity.
Pathologists determined that this injury was older than the injury to his face and eye due to differences in the stages of scarification associated with each injury.
The examination also confirmed that he was underweight, arthritic and had progressive and incurable kidney disease, as determined before his death. He also had a severe parasitic skin infection over his entire body, caused by demodectic mange and a fungus, specifically ringworm. This is the first documentation of a demodectic mange infection and a concurrent systemic ringworm infection in a California mountain lion.
Toxicology testing on his liver at the California Animal Health and Food Safety Laboratory (CAHFS) UC Davis revealed exposure to five anticoagulant rodenticides (AR) compounds. However, he had no evidence of AR poisoning (i.e., unexplained bleeding, injury, illness or death due to exposure to the toxicants).
These include first-generation ARs, diphacinone and chlorophacinone, and longer-lasting and faster-acting second-generation ARs, brodifacoum, bromadiolone and difethialone. Diphacinone was also detected in a sample of P-22's blood collected after he was captured, which may indicate recent exposure. Diphacinone was also detected in P-22's blood in 2014 when he was captured by NPS biologists and treated for a different skin infection caused by notoedric mange.
A separate CDFW study tested 247 mountain lions at the CAHFS lab. It showed that 96 percent of tested animals had exposure to one or more ARs. While felids tend to be more resistant to AR poisoning, there have been at least seven AR-related mortalities in Southern California mountain lions over the last 19 years.
Additionally, desmethylbromethalin, the toxic metabolite of bromethalin, was detected in his body fat. Bromethalin is a widely available rodenticide that targets the brain and affects the central nervous system. Signs of bromethalin poisoning include muscle tremors, seizures, hind limb paralysis, respiratory paralysis and eventually death. There was no indication that bromethalin exposure resulted in poisoning on P-22 medical or pathologic exam. How P-22 was exposed to bromethalin, directly or secondarily through prey, is unknown. However, it is believed to be the latter.
P-22 was likely born in the Santa Monica Mountains as the son of adult male P-1. NPS biologists first captured and radio-collared P-22 in March 2012 when he was estimated to be two years old. He was one of the most senior mountain lions in a study the NPS has conducted since 2002.
He persisted for more than 10 years in Griffith Park and in the smallest home range that has ever been recorded for an adult male mountain lion. But life on this tiny “island” did not come without consequence. After crossing two of the busiest freeways in the world, 101 and 405, he would unknowingly become isolated and never produce offspring. His movements and access to natural habitat and prey would be restricted, putting him at increased risk for interactions with people, collisions with cars and exposure to rodenticides. As extraordinary as P-22’s life was - surviving against all odds - it is an increasingly common reality for wildlife.
"P-22 was a fascinating animal to study," said Jeff Sikich, the lead field biologist of the NPS mountain lion study. "Not only was he an important ambassador for urban wildlife, but his scientific contributions were also many. He helped us understand how mountain lions coexist with humans in this complex urban landscape, and his legacy will live on through our heightened awareness of how to live in harmony with wild neighbors and growing public support for wildlife crossings."
Below is the redacted summary of the necropsy report
spread of the skin fungus was found in a lymph node. Generalized Demodex mite infections
suggest underlying immunosuppression or other disease. The skin disease likely contributed to
the deteriorating medical condition and systemic inflammation.
Age related changes were also noted and included heart valve disease, vascular disease, and
kidney disease. Changes were mild but were irreversible.
Toxicologic analysis of a post mortem liver sample for rodenticides was performed by the
California Animal Health and Food Safety (CAHFS) laboratory. Five anticoagulant rodenticides
were detected at varying concentrations. There was no evidence of abnormal hemorrhage or
coagulopathy that would suggest toxicosis, grossly or microscopically. Neurotoxic rodenticide
bromethalin was detected in a trace amount. There were no clinical signs consistent with
bromethalin toxicosis. Bromethalin does not typically result in microscopic lesions. Reported
amounts are below.

(Comment by Cummins. Notice how much higher the poison amounts are in P22 than reporting limit. He had large amounts in his liver. Much more poison was removed from his body via the liver and kidneys. It still does damage even after it's expelled.)

Desmethylbromethalin, Trace, 1.0
In summary, there was evidence of recent trauma to the head, a prior traumatic event resulting
in diaphragmatic tears and hernia, significant skin disease due to multiple infectious agents, and
