11. Mox Litter Tower
Who knew that something that looks like a trash can could be ideal for kitty waste? This ModernCat Designs creation was crafted to keep litter in the box. The tall, slender design and top-entry prevents curious canines from sticking their nose in your cat's business, while the grated top removes excess litter from your feline's feet. Obviously, the unusual entry point isn't for everyone; cat owners with overweight and elderly pets should avoid this choice.
