I took in two 8 week old kittens and I'm having some trouble litter training them. I'm not sure how high or low my expectations should be because litter training Kirk was a breeze. We brought Kirk home at 8 weeks old, showed him the litter box once (which was in the basement and we were always upstairs) and that was that. But Tojo and Penny are a whole other story. If they are confined to a small space (cat cage or exercise pen) they always use the litter box. But even just being out in the bedroom (which is small) they don't use it. Penny pooped on the floor twice and Tojo peed on the bed once and pooped on the floor. So I've had to keep them confined to either their cat cage (4'H x 2'D x 3'L) or their exercise pen (4' x'6'), which I hate. How do I work on this?
