10 Best Cat Litter Boxes 2026 in the United States

The Litter-Robot 4 Supply Bundle is a medium-sized, automatic self-cleaning cat litter box designed to make pet care easier. With dimensions around 27 x 24 x 29.5 inches and weighing 24 pounds, it’s quite sizable and may require a dedicated spot in your home. It features a top-entry design that helps contain litter scatter and reduces mess, while the plastic construction is sturdy and easy to clean. The standout feature is the self-cleaning mechanism that sifts waste automatically, so you don’t have to scoop daily—just empty the waste drawer when full.

This model supports up to four cats, making it suitable for multi-cat households, as long as each cat weighs over 3 pounds. The litter capacity is generous, accommodating standard clumping litter types. Odor control is strong thanks to included OdorTrap refills and carbon filters, which work together to significantly reduce unpleasant smells. Additionally, the Whisker app lets you monitor waste levels, litter usage, and even track your cat's weight, adding convenience and health insight.

Its large size and 24-pound weight mean it’s less portable and might not fit well in small spaces. Also, the smart weight sensors work best on flat, hard floors, so placing it on carpet might limit accuracy. Although the upfront price is higher than regular litter boxes, the bundle’s cleaning supplies and warranty offer good value. This litter box is a solid choice for cat owners seeking a high-tech, low-maintenance option with strong odor control and multi-cat support.

The PetSafe ScoopFree OpenSky is a self-cleaning cat litter box designed for convenience and odor control. Its size (about 21" long, 10" wide, and 28" high) accommodates cats of all sizes, providing ample space without feeling cramped. The open-top design helps reduce any fear or hesitation cats may have about entering the box, making it a comfortable choice, especially for cats that dislike enclosed spaces. Made of durable plastic, the litter box is built to last and is easy to clean.

A standout feature is the automated cleaning system that sifts clumps into a sealed 8.5-liter waste drawer, which can hold up to two weeks’ worth of waste for one cat. This eliminates the need for daily scooping, saving time and effort. The sealed drawer also helps control odors, complemented by a built-in deodorizer that the manufacturer claims reduces smells up to four times better than traditional litter boxes. The model is app-controlled via Wi-Fi, allowing you to monitor your cat's health by tracking weight and litter box usage, which can be especially helpful for multi-cat households or owners concerned about their pet’s well-being. It automatically refreshes the litter bed after each use, making it suitable for multiple cats.

The litter box's height of 28 inches may require more space and could be less convenient in smaller areas. While the open-top design is preferred by some cats, it may allow odors to escape more easily than covered boxes, although the unit's odor control features help mitigate this. Additionally, the reliance on Wi-Fi for health monitoring means it is best suited for homes with stable internet connections. This litter box is a good option for cat owners looking to reduce cleaning chores and improve odor control, particularly for medium to large or multiple cats. Its smart features add value but require some comfort with technology and available space.

The Fumoi Self Cleaning Litter Box is designed for multiple cats, featuring a large 95L capacity suitable for cats weighing between 2.2 to 33 lbs. The 15L waste bin can handle waste for up to 15 days, making it ideal for users who may be away for extended periods. Its advanced safety sensors ensure that the cleaning process pauses when your cat is near, providing safety and peace of mind.

The box operates quietly, maintaining a calm home environment, and its detachable, washable liner makes cleaning simple. Additionally, the built-in deodorizing design helps control odors, keeping your home fresh. The smart app control allows users to manage the litter box remotely, with features like auto-clean, waste disposal, and health tracking, though it is only compatible with 2.4G Wi-Fi.

This automated litter box can accommodate most types of cat litter, ensuring versatility. However, its size (21.6 x 19.6 x 25.8 inches) and weight (30.6 pounds) may make it less convenient for small spaces or frequent moving. The product's modern design and durable materials (polypropylene and ABS) are strong points, but the higher price and requirement for power may be a downside for some users. It is particularly suitable for cat owners looking for convenience and advanced features, especially those with multiple cats or busy schedules.
