Yes, I used to have to do this with Storm especially when I still had Cirrus. He never got it though and it wouldn't stop him from chasing Cirrus. Now I may have to start doing this with Sunny. This morning he jumped on poor Storm and it was almost a major cat fight. If I hadn't been there to break it up I don't know what wouldn've happened. Sunny still thinks that he should be the alpha cat. He doesn't realize that he just isn't cut out for this position because he's a goofball not a leader.
