Humans have a natural response to vomit. Things that are vomited out may be spoiled foods or contain bacteria from the person who vomited it. This is why vomit is disgusting to humans.
- jessedhillon 13y agoWhy do other animals eat vomit then? That sounds hardly like some instinct which should evolve only in us.
- iopq 13y agoSome animals have a practice of regurgitating food, so vomit is not disgusting to them (otherwise they wouldn't eat regurgitated food). Some animals need to eat feces to digest the food fully, or maybe hide their traces from predators etc. It depends on what is most useful to the animal. The definition of gross varies between animals.
