I agree, and he needs to be taught that it is not acceptable to chase the cat.
As soon as he starts with the cat, grab him and put him in a room by himself ... don't let him stay in a room with you or the cat. Only leave him in there for a few minutes. Let him out and if he does it again, grab him and put him in time out again. Just be consistent. Hopefully, he will learn that the behavior is not acceptable.
This has worked for me in many different instances.
