The Basics of the tail - !This is not a species trait! A vestigal tail is basically an evolved a remaint of the tail. Unlike a normal tail (Able to sweep bugs away, and used for balance) This type of tail has almost no positive impact. (Besides looks, Tentacle says.) Difficulties due to the tail- Lack of balance - this cat may fall over a quite little more compared to other cats, creating minor injuries No control over tail - The cat will not be able to wag, or even move the tail. Health problems - the fused tail often leads to major arthoritis, they also seem to get nerve problems as they age. Bladder problems- Cats with Vestigal tail sometimes can't control their bladder, which will happen to Ten during kithood but will learn to manage it otherwise. Positive facts about the tail- Tentacle likes it - this is rather unimportant, and wont affect them quite much. If they do decide to become a twoleg pet, (though unlikely) they will have a less likely chance to get their tail stuck? Neutral- Emotionless- if they seem to have a feeling they don't want to show, they can hide it from the other cat. The tail is a way you read their expressions. (Ex: Lashing tail)
