Some mammals can have a black, pink or spotted skin, depending on race - see for example humans or pigs. But I recently learned that this is not the case with mice. Even black furred mice have pink skin, and there is a rare mutation which produces black skinned mice.
I was talking with a friend about cats and we got to wonder if (domestic) cats are the type of animal which can have dark skin, like pigs, or the type which doesn't, like mice. The tons of cat related sites on the Internet seem to all talk about black furred cats only, or about diseases presenting with skin discoloration, but they don't mention the skin color. So, which type of animal are cats?
