thanks for the suggestions and replies.
DH cleans out litter every day but maybe he is doing crappy (ha ha, pun intended) job.
I have done the scratching paw thing with kitty. I have no idea how to tell if she doesn't like the litter. She
does use it but also goes behind the entertainment center too. I certainly don't want to have to try out every litter on the market.
I did find out that the previous owners had her poop on newspaper.
Amy, that is funny about the cats using the sink!
I am perplexed. Cat on thin ice around here.
