"A feral cat is one that has no interaction with humans whatsoever. A stray or domestic cat will roam a suburb, and be fed by people, but a feral cat will flee and do all its own hunting." MattM
A feral cat is an unowned cat (Felis catus) that lives outdoors and avoids human contact: it does not allow itself to be handled or touched, and usually remains hidden from humans.
