P-54: Survivor CatFemale | Born January 2017 | Alive
In late February of 2017, NPS researchers marked this kitten while the mother, P-23, was away from the den. P-54 was thought to be the only known kitten from P-23's third litter. However, we later discovered (through remote camera photos and videos) that there was another kitten. We have not confirmed who that kitten is.
P-54 also has a 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.
Recent genetic testing has proved that P-12 is P-54's father (and grandfather)! Based on GPS data, we know that P-23 and her half sibling P-30 had traveled together for three days, a possible indication of mating, but not a guarantee. Approximately 90 days later, researchers saw a series of localized GPS locations, indicating that P-23 had recently given birth. Females, however, can breed with multiple males during an estrus cycle, a recurring period of sexual receptivity and fertility in many mammals.
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 27, 2018 on the Pepperdine University campus is P-54.
