Only in very cold climates and in winter feed grounds do Lions come back to a kill, these are Lions raised on elk feeding grounds....

In the desert SW it just doesn't happen, but never say never there may be an exception or demented Lion out there somewhere that will....

As to california Lions who knows, hell they jump on and eat people, they have lost all fear of man as have the bears and good for them..Any bunch of people that would stop all hunting then whine about losing dogs, kids and old folks, begged for it, it was bound to happen and they were forewarned many times before the laws were passed.........
