The changeable and macho kittens, now accepted as P-46 and P-47, were apparent in December in a well-hidden den in a limited breadth of the western end of the mountains, the National Esplanade Account said. Both accept been built-in with tracking accessories to adviser their whereabouts.
The esplanade account has been belief the abundance lions in and about the Santa Monica Mountains back 2002, accouterment a abundant attending central the animals' activities -- and axis the ambrosial kittens abnormally into burning favorites on the Internet.
"We abide to see acknowledged reproduction, which indicates that the superior of the accustomed abode is top for such a almost urbanized area," Jeff Sikich, a biologist for Santa Monica Mountains National Recreation Area, said in a statement.
But what charcoal a abstruseness is who fathered the kittens, who were built-in aboriginal endure month. The mother, P-19, had two antecedent litters as the aftereffect of inbreeding with her father, P-12. The endure accepted action associated with P-12 dates to March 2015.DNA testing is underway to actuate whether the new clutter was aswell fathered by P-12, or conceivably a anew apparent developed macho accepted as P-45. The new macho has been tracked back Nov. 21 and has spent a lot of of his time in the western end of the mountains.
It is alien how P-45 concluded up in the breadth and how he ability be accompanying to the added lions. Sikich is hopeful that the kittens' ancestor is different to P-19, as inbreeding has been a botheration for lions in the Santa Monicas, area the citizenry is "essentially trapped," the esplanade account said.
Inbreeding leads to low abiogenetic diversity, which can eventually advance to low reproduction, Sikich said.
"Our abundance lions in the Santa Monica Mountains ... accept the everyman abiogenetic assortment anytime recorded of any abundance bobcat citizenry besides the Florida bobcat that went about extinct," Sikich said.
A proposed wildlife bridge over the 101 Freeway in Agoura Hills would affix ample swaths of accustomed acreage from the Santa Monica Mountains to the Sierra Madre, which could advice break the abiogenetic assortment problem.
On Thursday, the National Esplanade Account acquaint a video of the kittens squeaking in their den while their mother was away, and addition video featuring the kittens and their mother. The den was hidden a part of ample boulders and blubbery brush. P-19 has been tracked back 2010, if she was alone a few weeks old. Of her endure clutter of kittens -- called P-32, P-33, P-34 -- two are dead.
This is the ninth clutter of kittens apparent by esplanade account biologists at a Santa Monica Mountains den site. Two added litters were apparent if the kittens were already at atomic 6 months old.
The kittens, Sikich said, accept "many challenges advanced of them," including artifice added abundance lions, bridge freeways and ambidextrous with acknowledgment to rat poison.
"Young kittens, a big claiming for them is alienated any developed male," Sikich said. "Adult macho lions accept been accepted to annihilate adolescent kittens."
