Oh, yes, indeed. I think he should have his own series, where he goes around acting like a normalish cat (normal as cats ever get) and then just suddenly going into rage-mode trying to catch mice or bat the fish out of the koi pond or in one of those random fits cats have where they race around the house yowling for no reason at all.
Also, a little old lady should own him and give him his true name (RUFFLES!)
