When do kittens start to lose their teeth and how long does that usually last? Also do cats regrow a tooth if it looses one after they loose their baby teeth? The reason I ask is because I think Booda had a tooth cracked at the vet the other day when he was put under for surgury and today when I was trying to give his pills it broke off really easily. I didn't even know it happened until I saw it on the floor.
