It's interesting how different animals respond to suddenly having tiny infants that want to nurse on them. Cats are like you could add a half dozen baby hedgehogs and they wouldn't care, whereas horses are like 'I might kick this to death, I haven't decided yet.'
(Yes I'm watching cat fostering youtube)
@Satsuma Felidae as a whole seem to be on some insane maternal hormones. There's a case in the literature where a lioness killed a deer and then tried to raise the deer's faun? (spoiler this didn't work out well for the faun, sorry!) Although I guess that's also a cooperative rearing species, so we need to see if we can get a puma to do it, I guess.
