However it is possible to breed healthy Folds, if you cross a fold with a moggy or a shorthair/longhair, or other breed. They will have louder, longer cries, long "full" tails, and will be excited/running a lot easier and faster, and a lot more playful. Though still more docile than most cat breeds.
