You can call me batshit crazy, but it grinds my gears when people talk about animals like they are stupid because they aren't capable of what we say we are. Their intelligence is different than ours, doesn't make them not intelligent or less intelligent. They evolved to survive their niche.
There are plenty of accounts of dogs and cats nurturing orphaned prey animals and rescuing their handlers or families when they are not trained to do so. This seems documented more in mammals, who are wired to be more social creatures.
