The unit is small and affordable, making it a great choice for pet owners in apartments or other small spaces

The CatGenie is great for people who care about hygiene and who would like as little involvement with their cat litter boxes as possible. If you have a spare bathroom or some other space with cold water access and an outlet, it'll work great for you. We also recommend a litter box that uses silica crystals. This can be an excellent option if you dislike clay dust. It also absorbs smells well. However, you may want to acclimate your cat to crystal litter before springing an automatic litter box on them, since not all cats adjust well to the silica crystals. Since it doesn't have the wide open entryway of the Litter-Robot 4, the Leo's Loo Too is more comparable to the Pura X in its operation and was comparably quiet when running a cleaning cycle. Otherwise, it follows the classic design of automatic litter boxes with a rotating barrel passing through a grate, leaving behind solid clumps, which are dumped into a lower reservoir. CatGenie requires NO LITTER, only cat-approved, septic-safe Washable Granules that never need changing. When kitty goes, liquids drain through the non-absorbing Washable Granules. Newcomer Natusan is a 100% sustainable cat litter that absorbs up to seven times its own weight, forming tight clumps that we found super easy to remove. The tiny wood pulp-based granules (all a by-product of the timber industry) smell lovely, and absorb unpleasant whiffs really well to keep your home pong-free. We did find a few clean particles in the carpet, courtesy of our long-haired cat, but the dirty litter clumped so well that it didn’t end up outside the box.On occasion, clean cat litter may fall into the disposable waste tray, which is a bit wasteful from a financial aspect Users have noted that sometimes the waste drainage system can get clogged up with kitty hair—but consider it one more incentive to maintain a regular grooming routine for your furball (especially if she's long haired) Occasionally, the device may make a grinding noise—fix by cleaning litter out of the space between the base and the rotational plate While we think the Litter-Robot 4 is a substantial improvement over its predecessor, the Litter-Robot 3 Connect is still a high quality product. It's a little larger (more than 2 inches wider), less attractively designed, and a little louder, but the reduced price might make the previous Litter-Robot model worth your consideration.

It's normal for there to be a foul odor emanating from the unit during the cleaning cycle (consider installing the unit away from high-traffic areas in your house) Let your cat relieve herself and satisfy her covering instincts with these washable and reusable granules instead of normal throw-away litter. This thing looks and works just like a little feline toilet!Clumping cat litter is made from material that soaks up liquids to form solid clumps when wet. These clumps are easy to remove without having to replace all the litter at once, which saves time and money. However, clumping litter can be swallowed by kittens and cause dangerous internal obstructions, so we’ve recommended a few non-clumping litters for very young cats. What is cat litter made from? Cleaning the Litter-Robot 4 was also a cinch. The bags used in the reservoir are tall enough that even an over-stuffed reservoir is easy to empty—simply lift up the edges of the bag and use that extra height to tie it off. There's a QR code on the bottom of the reservoir that provides a retail link for easily purchasing new bags, smell filters, and even litter (but it doesn't require proprietary litter, and worked great with our generic, store-bought litter).

But if you know your cat is ready for crystal litter, then the PetSafe Scoop-Free Smart Covered Self-Cleaning Litter Box is one of the best ways to take full advantage. The automated box rakes through the litter 20 minutes after your cat is done using it, moving solid waste to a separate compartment. Meanwhile, the silica crystals absorb urine and other smells. Once a month (for a single-cat household), you simply slide out the entire tray, put a lid on it, and throw it away. The automatic cleaning is remarkably quiet and the comb slowly passes through the litter to weed out solid waste. You never have to touch—and you barely even have a chance to spot—the waste your cat leaves behind. The Litter-Robot 4 also shares with its predecessor a very large silhouette. Anyone living with cats in a small apartment should measure first, and have a good sense of whether they have enough room to accommodate the Litter-Robot. It's sufficient to cleanlyabsorb up to 20 days worth of urine, or until the disposable litter tray needs to be tossedIt's easy enough to use that anyone in your house can be part of cat litter duty! Simply roll it upside down and then right side up—remaining waste clumps are shuttled into a disposable waste tray The Whisker Litter-Robot 4 is not merely an iterative improvement on our former "Best Overall" automatic litter box, the Litter-Robot 3 Connect, but a comprehensive upgrade. In lab testing—and throughout weeks of follow-up testing with real cats in a home setting—our testers expressed repeated admiration for various features, design improvements, and their overall experience using the Litter-Robot 4. Odor control was also excellent with the Smarty Pear, even with the large waste drawer, which enables you to go a week or more without emptying. In a tester home with a single cat, the reservoir bag could remain in place for up to a month without any noticeable odors—but the bag was cumbersome to remove. In homes with multiple kitties sharing the Smarty Pear, we recommend changing the reservoir weekly and taking advantage of the additional spin cycle feature that ensures waste is filtered out.
