I think away and cut off from the cat is best if you're going to play and energize him. There is a high probability of him turning his attention and energy to the cat at the drop of a dime in that state.

Anytime he and the cat are together and have access to one another you just want to promote relaxation and stable, calm energy. It's unfair to let him escalate and then instantly try to control and restrain him from the cat. Not to mention, you're making your job so much more difficult.

Yeah kind of defeats the purpose.I think we'll make the computer room his new indoor play room and just make sure he has calmed down before we enter the main living area again.
