New Kitten

I have a 13 week old male domestic shorthair and an 8 week old 1/2 Bengal female kitten. The two of them "play" all the time, but I think only the 13 week old thinks its playing. The Bengal allways starts/continues the same roudy behavior, but she GROWLS A LOT and hisses constantly, where my male just makes playful little chirping noises. Now the little girl is starting to hiss and growl when I try to pick her up, etc... WHAT'S GOING ON?

Also, I wanted to add, my male kitten ALLWAYS smacks the little female in the head, or in the butt, but he never seems like hes doing it in a mean way, he never hisses or puffs up. How can I get him to stop doing this, and leave her alone? He REFUSES to leave her alone for one second. Any suggestions?

How long have they been together? It sounds like they are trying to play but maybe the male is getting to rough. 8 weeks is still pretty young and she might not understand yet that it is just play.

You might try separating them in separate rooms for awhile so they can get a break. It sounds like the male is more than thrilled to have a playmate but the female is not sure of herself or her surroundings so she is fighting back the only way she knows how.
