Cows are a species of villager in the Animal Crossing series, being the female counterpart of bulls. The main difference, aside from the cows having more feminine features, is that the bulls have curlier, pointier horns.
There are eight cow villagers so far, none of which are sisterly. Additionally, four of them have been absent since Doubutsu no Mori e+. Three cows are normal, three are snooty, and two are peppy.
