Sammy and Casie

[Saphire_1975]

As many of you know I have been going through introducing 8 month old Sammy to 9 week old Cassie. It's taking a lot of time and it's going good. But, it seems that when Sammy tires of the chase and wrestel game he get's to rough with Casie (he bites her stomach) and I have to seperate them, which is what he wants. When he get's to rough he get's a 15 minute time out in the bathroom and she gets to roam the house. But, he likes the time alone to eat, drink use the litterbox ect. It's starting to feel like he's being mean when he wants some time to himself also when he comes out Casie is often back in her room. So he get's his way. She also uses this ploy and cries when she starts losing so I call him away and she can start again. Also all they do is chase eachother. Should I keep on seperating them or should I just call him off? I'm thinking of when he gets out of time out for Casie to still be their that way he knows that he needs to get along with her or be punished, and that she's not going anywhere because he was rough. Would this cause jealousey?

Thanks for any help, Saphire
