Puma Profiles: P-65

Female
Initial capture date: March 2018
Deceased

P-65 was a young female that was one of the 11 mountain lions we were tracking that were in or around the fire perimeter when the Woolsey Fire broke out on Nov. 9, 2018. She managed to survive the fire, but her entire home range was within the burn area.

She was found dead by biologists on March 4, 2022, near a stream in the central Santa Monica Mountains where she lived. She was estimated to be around 5 years of age.

She had a severe case of mange especially on her face and head, as evidenced by hair loss and skin encrustation. She was also extremely emaciated. Read the press release here.

After she died, she was taken to the California Animal Health and Food Safety Lab (CAHFS) for a full necropsy and testing. Toxicological tests revealed that she was exposed to five different anticoagulant rodenticides, also known as rat poisons, and to bromethalin, a neurotoxic rodenticide.

Biologists say that P-65 was an interesting cat to study.

She made history on Aug. 21, 2019. when she became the second radio-collared female mountain lion to cross the 101 Freeway moving northward into the Simi Hills. It occurred between the hours of midnight and 2 a.m.

Researchers are not sure exactly where she crossed along the 101, but GPS data indicates it was in the Liberty Canyon area of Agoura Hills where a wildlife bridge has been proposed. She was not picked up on any of our remote cameras monitoring wildlife movement through a culvert or underpass in this area, so biologists believe she most likely ran across the actual roadway. P-65 crossed the freeway once again on Nov. 6, 2019. She is now back in the Santa Monica Mountains.

On July 6, 2020, biologists found P-65's den and tagged three kittens -P-88, P-89 and P-90, a female and two males. P-63 is likely the father. They traveled together for three days in March 2020. This may also be P-65's first litter.

P-33 is the only other collared female mountain lion to have crossed the 101 Freeway. She trailblazed the way when she crossed the 101 northward into the Simi Hills in March 2015. This crossing occurred on the far western end of the Santa Monica Mountains, near the border of Thousand Oaks and Camarillo. She eventually made her way to Los Padres National Forest, which is the nearest source population for mountain lions. This marked the first documented and successful dispersal out of the Santa Monica Mountains and into a new home range. Sadly, she died of unknown causes last summer.

P-65 spent all of her time within the fire perimeter, likely finding unburned portions and opportunities to prey on mule deer in the area. She originally earned the nickname "Coastal Cat" because of her earlier inclination to stick to the coastal areas west of Las Virgenes Road.

She was first captured and collared in the central portion of the Santa Monica Mountains in March 2018.
