My Kitty is a darling in the daytime, but as soon as it becomes night out he turns into evil cat. He stalks me and attacks my ankles and beats up my hand as soon as I touch him.

What else does he do when the sun goes down...  He runs like a maniac and terrorizes the carpet.  When I tell him to stop he will just do it again later. He won't use his kitty litter until I scoop it for him and he will actually meow beside it until I do scoop it.

He only likes it when I give him fresh food. He won't eat the old stuff. He has the absolute run of the house!
