This female who roamed the Santa Susana Mountains is thought to have been born in 2011 or 2012. She entered the study in April 2015 and, along with her daughter P-40, were the focus of some amazing photos that captured them feeding on a deer. P-38 was the father.
P-39 died trying to cross the 118 Freeway in early December 2016. While she resided in the Santa Susana Mountains, she successfully crossed the freeway into the Simi Hills a few days prior to her death. Two of the kittens, P-51 and P-52, also died trying to cross the same freeway in separate incidents over the next two months. P-50 was found to be alive and healthy in spring 2017.
