my cat blue has a litterbox problem. he goes to the litterbox, but he won't squat.. he just stands and pee goes everywhere. he has never been the best at covering his business(he usually pawed more on the outside of the box than the litter). and when he goes number two, he puts all four paws on the edge of the litterbox before he will go. the litter is always clean, and my other cat fritz doesn't have this problem. they are both declawed, neutered, and very young. blue is only 2, will be three in february. is this territorial? does he not like the feel of the litter? although, we have tried others, and the natural, woodchip(?) kind he won't even use, instead using the bed or couch. could this maybe be a kidney infection?
