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 Legacy ScoopFree Crystal Pro is a front-entry, self-cleaning cat litter box designed to make litter maintenance easier. Its dimensions (27.6" L x 19.1" W x 16" H) provide enough space for most cats, accommodating all sizes. Made from durable plastic, it includes a hood for privacy and odor control. The standout feature is its automatic cleaning system, which uses motion sensors to rake waste into a sealed disposable tray, cutting down on daily scooping. The crystal litter absorbs liquids and dries solid waste to reduce odors and mess, with low tracking crystals that help keep your home clean. The disposable trays simplify maintenance but mean you’ll need to replace them periodically, which could add to ongoing costs.

Another helpful feature is the built-in health counter that tracks your cat’s litter box usage, alerting you to changes that might suggest health issues. While the box is designed to contain odors well and minimize cleaning effort, some users might find the initial setup and dependent supply of crystal litter and trays a bit pricey. Also, the front-entry design works well for most cats but may not suit cats who prefer top-entry or have mobility challenges.

This litter box suits cat owners seeking a convenient, low-maintenance option with health monitoring, especially for indoor cats who adapt well to crystal litter. Potential buyers should consider the cost and need for regular tray replacements when deciding if this product meets their needs.

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.
