This cat box is fantastic! Its huge enough to fit multiples cats in there, and its so well made that it traps litter and most odors in there as well. my bathroom has never not been covered in cat litter, until this covered cat box entered our lives. The locking clasps/clips really do work, and are incredibly easy to operate. The hard plastic surface is very easy to clean, and is nonporous so there is no grooves or holes for stuff to get stuck. I really recommend this covered cat litter box to anyone with a cat, or even multiple cats. The odor trapping is so well done that guests don’t realize we have a cat until she comes out from hiding! Everything about this litter box, is simply fantastic. Will be money well spent, I guarantee.
