I think he is just playing with the cat. We had a Snorkie and when our cat would come into the mobile home the Snorkie would jump off my lap and chase the cat as fast as she could to the other end of the mobile. Then they would flip around and the cat would chase the Snorkie. Back and forth they would go. they loved playing together. At first I was concerned but then I realized it was just play.
