As I've mentioned before, one of my "indoor" cats decided he wanted to be an "outdoor" cat. Since I feel bad when my pets go use other people's yards for their own personal toilet, I didn't want to let him run loose. Thus, the leash. Which he does well with. On a whim, I stuck an Avon box outside and the husband put an old rug in it. Now I have a hard time getting Rosco to come in, even while it's raining!
