I'm wondering about cabin fever/winter blahs too.

Willow has turned into a royal *itch lately. She hisses and spits at all the kitties. She gets jealous if you give another kitty attention and tries to force her way between you and the other kitty. She grabs her brother by the neck and bites down pretty hard and growls.

Itty-bitty Pepper smacked the crap out of her and put her back in her place but Willy's feelings are hurt and he just tries to avoid her. But, he's sooooo sad.
