My Sir Thomas gained a little sister a year and a half ago. He went from being a loving, very cuddly boy to a nasty tempered demon. To this day most of the time he spits and hisses at me, and he sprays anything and everything several times over. Luckily his spray has very little odor. But he seems to be obsessive-compulsive about it. I want my mild-tempered, loving, non-spraying cat back. Is there any way I can help him to like me again?
Who wants a mild-tempered kitty? What would life be without hissing, spitting, biting and the like? For the spraying, see my advice to Rommina. You could also try feeding Sir Thomas and Little Sister lots of tuna. Just be sure to give plenty to both of them. When dirty little D (he WAS little then…) came into my house, I was pretty irritated for a while, but my Human Typing Slave gave me tuna and treats in a special location away from gnoshing D so the little bugger couldn’t raid my stash. That helped.
