We adopted our recovering feral kitty several years ago, so our yorkies were coming into HIS house when they were each adopted. It was a success from the very beginning--he and our male yorkie became immediate wrestling and racing buddies. With the recent addition of a second yorkie, we were beyond happy to watch them discover that they could all three play. The cat even seems to view the younger yorkie as his charge and he keeps a check on her as though he thinks we don't know what we're doing.
