My 10 mouth old yellow tabby is very active. Sometimes when I am at the computer working, he decides it is """PLAYTIME""". He wears a collar and one day I twisted one end of a pipe cleaner around his collar and brought the rest up so it looked like an antenne. That kept him busy playing while I was able to continue working, although I must admit I spent more time watching him "PLAY" when I should have been working. I don't think I could survive without my two cats, they are great listeners and never talk back...what more could you ask for.....
