My cat has a short little crooked tail. We have never actually seen the bone because he has always had a round, very fluffy tail. He has liked most of the hair off of his tail over the past couple days. We don't know why. He is now starting to lick off the hair on his belly area. He is an indoor only cat. The only change in our house is that I started using a Swiffer a couple weeks ago. Could he have gotten some Swiffer on him and is having an allergic reaction. Anybody ever experience their cat pulling their hair out like this and he is also spitting up huge fur balls. Thank for any information you might have
