For the price of similar products this ticks off many boxes.  I'm a bit iffy on the extra shelf as I still havent been able to find much purpose for it.  Our smaller dog still finds his way in sometimes but the pet crate deters his efforts -- somewhat.  Please keep in mind this is an average sized crate so you may need to downsize on the cat litter box size... I found that it helped with the litter getting everywhere + a litter mat.  My only other complaint is the caps that cover the screws keep popping out so while the structure is sound, it isn't the stronger piece of furniture you'll find.  The door also doesn't stay open which makes scooping time a little bit of an annoying process.
