A two for one special! If changing a cat's litter pan and the cat starts trying to get in it, consider that the reason why. It may not be curiosity about what you're doing. He may actually have to pee, and will do so where he sees fit if you don't let him in the pan. Also? Make sure you have a sufficient amount of litter before deciding to change it instead of scooping it. LFM-double-Fail
