Reintroduction between a kitten and ferret?

Kittens are crazy! My cat chilled out a bit once he was fixed. As for your cat, I think he'll chill with age, but for now he is just a normal crazy kitten. I wouldn't tolerate him biting you though, that get really bad when they get bigger. Cat bites are the worst! To help my cat stop biting, we started using a spray bottle. It did the trick. Good luck!
