How many litter boxes should I have for my two cats?
I recommend one litter pan per cat plus one more. This may sound like a lot but, in fact, some cats will only urinate in one box and pass feces in another. Also, some are reluctant to go where others have gone before hem. This is why it is very important to clean out litter pans every day. I have seven cats and ten litter pans that are cleaned each day. I have seen cases through the years in which, after much questioning and ruling ut medical problems, a cat starts to urinate or defecate outside the litter box. The problem is rectified by adding another litter box or two or changing the kind of litter used. Some cats do not like clay, clumping or scented litter. Cats, like people, have likes and dislikes and this applies to “bathroom” facilities as well.
