IRIS Large High back Open Top Cat Litter Tray Litter Pan, White

It is deep enough for my boys but the outer shield helps keeps the litter inside well. The curvy shape and being black helps it from being an eye sore.

We've had one of these exact same oval, shielded Iris litter pans for a few years and love it because it minimizes scattered litter and sprayed mess, and doesn't tip over when one of our kitties insists on sitting on its low lip edge while using it. So we bought a second one to use in another location, but unfortunately it's arrived looking clearly used with litter dust adhered in a circle all around inside the shield and some in the pan, so it will be returned. We'll try ordering another one if it's still on sale.
