Female | Born January 2017 | Alive
The only known kitten from P-23's third litter, P-54 appears to be another product of inbreeding. Based on GPS data, P-23 and her half sibling P-30 were traveling together for three days, a likely indication of mating. Approximately 90 days later, researchers saw a series of localized GPS locations, indicating that P-23 had recently given birth. If genetic testing confirms that P-30 is the father, it would the first documentation of him fathering kittens.
In late February of 2017, NPS researchers marked the kitten while the mother was away from the den. She has only one known half-sibling, P-53, from a litter born in June 2015. Kittens from that litter (including P-43) and a previous one (P-36 and P-37) all died as a result of predation from other wildlife.
In January 2018, P-54's mom, P-23, was found dead near the side of Malibu Canyon Road, likely from being struck by a vehicle. P-54 was one year old at the time of her mom's death, which is typically around the time when kittens leave their mother. Fortunately, she survived. DNA results show that the young female mountain lion our biologist captured on February 27th on the Pepperdine University campus is P-54.
