Cleaning a litter box is never much fun. That’s why you see so many different litter box designs to cater to the cat, but rarely to the human. Some of the more advanced litter boxes offer motorized self-cleaning options, but that still requires a human to dispose of the mess afterwards.
Since people use flushable toilets, it only makes sense for cats to have a flushable toilet as well. The Catolet is a unique litter box that dispose of solids wastes into a sewer and cleans its belt so it offers a clean surface for the cat to step on later.
If you dislike cleaning litter boxes, consider contributing to the Catolet Kickstarter campaign and see if your cat might like the benefits of a flushable toilet just like you enjoy.
