Dogs using the cats litter box?

Dogs using the cats litter box? I have a friend that was trained to use the cats litter box. Heh. Kind of a whimpy little dog if you ask me. Being forced to use the litter box would make me want to bite someone. The litter box is for cats, not dogs. Dogs need to go for walks. You know what I'm talking about. We like to smell everything. Then are eventually inspired when the timing and location are just right. Just for kicks, I was bored the other day and decided to try it. Don't get me wrong. I wouldn't use the litter box instead of going for a walk. But in some cases, it's not that bad. I didn't climb in the litter box. I just stood out side of it and lifted my leg. I have pretty good aim. So they don't care if I pee in the house. As long as it is in a box with sand in it. Crazy humans.
