This has got to be the coolest litter box ever. (At least the coolest under $90)
When we got Fenris, I bought a Self-Cleaning Litter Box at Target for $19.99. I didn't figure it would work, but it wasn't too much more than a simple covered box, so I thought we'd give it a shot. Guess what? It WORKS! It's awesome! The link should take you to PetSmart, where the litter box is $24.99. Well worth that price if you don't have a Target!
