long hair. it's either short hair or long hair. how old is your kitty. sometimes medium hairs fluff out to long hair in colder spells. I know my forest cats all do that.I have a cat I got back from the shelter, and they said he was a domestic medium hair. So how would you describe him if that doesn’t exist? He does not have the typical fluff of a long haired cat except in his tail and his guard hairs are a different color from his undercoat
