Neakasa M1
Best for large cats that dislike hoodsOpen top box for big or wary cats, rated up to 33 lb
Self cleaning litter boxes sift clumps into a sealed bin after each visit, so you empty a drawer every week or two instead of scooping daily. The ten below are the models on sale in the US as of October 2026 that independent reviewers rate highest, from the $340 PetSafe SmartSpin to the $899 Litter-Robot 5 Pro. Check your cat's weight against each box's range and look closely at safety sensors before you buy. How we score.
