You don't know what "Manx" means do you? The cat on the mousepad CLEARLY has a tail. #fail #catphoto http://t.co/hT1OqolX # @annaonthemoon But they're defined by having either a tiny, stubby tail or being tailess entirely; it's the defining characteristic! LOL # @annaonthemoon *chuckles* Yeah I know. I just couldn't get by tail + Manx…
