Because I'm not seeing what is going on it's hard to say exactly what is happening. But from the way you are describing it, it sound more like play/dominate issues. Your 11 month old even though he is only playing is telling the younger one that he is the boss. My cats all went through this. I agree with Madame Alto. I would not allow unsupervise play sessions. Keep the cats seprate while your not home. Once the 8 week old is bigger and able to hold her own it will be ok to leave them together. But also, it's not good to give kitten free run of the house when your not home. I did that with my last one (luckly I was home) she some how got her hind leg caught in the slates of the bar stool. And was hanging there. I don't know what would have happened if no one was home. From that point on she was always put in a bedroom or bathroom when no one was there. Once she was bigger we let her have the house back.
