Well, when I put them together I let them mount it and get over it lol. And they were grooming and not fighting so I thought they could stay together in one day. I didn't do it gradually. But they did exist in the same room for a year so they knew each other existed. And yes, he had stuff to chew n stuff. He was just bored with them. He was hard to please. Then I made a big play yard outside, and he seemed to like that. They use to have free run back yard, but one got under the fence some how. Then I made the play yard.
