14 yr old neutered male housecat.(not housecoat autocorrect) has become a bit niffy, not pooey, or pissy, just ugh. As he loves sleeping on us it would be nice if he didn't stink! He eats Sheba or Cat and fiddle. If it was summer I would bath him (yes, he's that soft). He's been fleaed regularly too. What can I de stink him with?
