I have 4 cats, enough said! I got a catgenie and within a couple days they all figured it out. 3 of my 4 cats are very sensitive to having clean litter. They will poop next to a dirty box so this was a godsend. No more scooping 2-3x a day!! My boyfriend is a much happier man! My cats are happier cats! The house always smells fresh and clean now. No litter smells and no more accidents.
