Amazingly enough, they all get along. Scout is about 10 weeks older. When he is tired of playing with them, he hops up onto the highest perch of the cat post and watches them. Gigi accepted him right off. She kind of worried me because of her reaction to Scout at first, I was afraid she'd be a little priss to Bix. But, she loves him. I guess she wasn't intimidated like with Scout because they're about the same size. It is soooo cute to watch them play, like two big cotton balls rolling around on the floor!
