Rocky is having trouble with my other 2 male cats they are 4 and 6 years old rocky is 6 also. The other two mind there own business and rocky sometimes attacks them. Rock came from a shelter and was very shy when we got him he finally came around to us, we became friends. It seems he has a problem with just the cats. We think he came from an older women and was the only cat. At the shelter he was kept apart from the general population being so shy. My question is can he finally accept being with the other cats? They really been interacting only a couple months. Also is there the possibility he would be happier in a one cat family?We would do whats best for him .
