They may or may not. I've seen a documentary once about a Jaguar that killed a gazelle (I believe) that just had its calf born. The mother was dead and being eaten, the calf had nowhere to go and just stayed with the Jaguar who then sort of accepted the calf and let it live. They became this super weird parent - offspring pairing that, of course, didn't work. The calf needed feeding, there were obviously no gazelles near, and if I recall correctly it either died soon from malnutrition, or after a few days the Jaguar just killed it anyway. The narrator speculated that the Jaguar might have lost its offspring shortly before and still had that motherly instinct.

Moral of the story is. Animals are driven by instinct and hormones, don't trust they will not shred you.
