This male is the surviving sibling of a litter of at least three kittens born to P-39 in the Santa Susana Mountains. It was her second known litter. P-38 is suspected to be the father based on GPS locations of him traveling and spending multiple days with P-39 months before they were born.
P-39 died trying to cross the 118 Freeway in December 2016, leaving the litter to fend for themselves. P-51 and P-52 both died trying to cross the same freeway over the next month and a half.'
P-50's fate was unknown until May 5, 2017, when wildlife officers from the California Department of Fish and Wildlife responded to reports of a mountain lion in a gardening center in Chatsworth, south of the 118 Freeway. He was found to be healthy and in good shape. Officers tranquilized and moved him to the Santa Susana Mountains.
