I took in a stray on Halloween Night. I have two other cats and the new kitten is showing some behavior that my others have never shown. I have named him Jack and he is not fixed and he hasn't received any shots yet due to my knowledge. We are getting the first round tomorrow. He is very spastic though. i am guessing he is 3 to 4 months old and he is a sweet guy, but half the time he is just going crazy! And he bites, HARD! He just seems to get way over stimulated by things. He is literally bouncing off my walls. I was just wondering if this is typical behavior for a young male kitten? My other 2 are girls. I need help!
