> Why is a cat friendly towards human visitors, yet hostile towards feline ones? My (normal size) cat was friendly to human visitors as long as they were really big (100Kg+). It occasionally attacked other human visitors, presumably because they were easily scared. So perhaps it's just trying to assert dominance, regardless of species, but based on its estimated chance to succeed.
