I knows she's a kitten (4 1/2 Months) and since I've never had a cat inside and she chews on everything like she's teething this may be normal, but I was petting her and she started to smack her mouth like a hair was there or something and then something come out of her mouth. I heard it hit the desk and looked. It was a tooth. Is this normal or should I countinue freaking? She's acting Ok and went and ate some more of her canned food.
