10 Best Litter Boxes 2025 in the United States

The Litter-Robot 4 Supply & Accessory Bundle is a medium-sized, automatic self-cleaning litter box designed to make cat care easier. Its large size (27"L x 24.25"W x 29.5"H) and plastic build make it durable and suitable for indoor use. The box features a top-entry design and includes a ramp, which helps cats enter comfortably and keeps litter contained. One of its biggest strengths is the self-cleaning feature—after your cat uses it, the unit sifts waste automatically into a drawer you only need to empty occasionally, saving you from daily scooping. This makes it an excellent choice for busy households or those with multiple cats (up to four). The product also includes odor control features like OdorTrap packs, carbon filters, and a special mat to reduce litter tracking and smells, helping to keep your home fresher.

The included app lets you monitor litter levels, waste drawer status, and even track your cat’s weight, adding convenience and health benefits. The unit is quite tall and fairly heavy at 24 pounds, which might be challenging if you have limited space or need to move it frequently. Additionally, the auto mode works best for cats weighing at least 3 pounds, so it may not be ideal for very small kittens. Although the price is higher than traditional litter boxes, the combination of self-cleaning, odor control, and smart features delivers strong value for those seeking a low-maintenance, cleaner environment for their cats.

The PetSafe Legacy ScoopFree Crystal Pro is a front-entry, covered litter box designed for indoor cats of all sizes. It measures about 27.6 x 19.1 x 16 inches, which is a good size for many cats but may be a bit bulky for very small spaces. Its standout feature is the self-cleaning system that uses motion sensors to rake waste into a sealed compartment, reducing the need for daily scooping. It uses disposable trays filled with crystal litter, which effectively absorbs moisture and controls odors by dehydrating solid waste, helping keep your home fresh. The crystals also track well, so less mess gets carried outside the box.

Another useful feature is the integrated health counter that records how often your cat uses the box, which can help you notice changes in their bathroom habits early. The covered design offers privacy and helps contain odors but might not suit cats who dislike enclosed spaces. While this litter box offers great convenience and hygiene, the cost of replacing disposable trays and crystal litter could add up over time. Also, the unit weighs over 20 pounds, so it may be less convenient to move around.

This model is well-suited for busy cat owners looking for a low-maintenance, hygienic solution with health monitoring, especially if they are prepared to invest in disposable trays and crystal litter.

The PetSafe ScoopFree OpenSky is a self-cleaning litter box designed to take the hassle out of daily scooping by automatically sifting waste into a sealed drawer that lasts up to two weeks for one cat. Its large size and open-top design suit cats of all sizes, providing a comfortable space without the feeling of confinement that covered boxes might cause. The open entry also reduces anxiety for many cats, encouraging use. Made from sturdy plastic, it’s durable and easy to clean.

One of its strongest points is odor control, with a sealed waste drawer and built-in deodorizer that reportedly reduce smells up to four times better than standard litter boxes. This can be a big plus in indoor homes. The box also offers health monitoring via a smartphone app, tracking your cat's weight and litter habits, which can alert you to potential health issues early on. This feature requires Wi-Fi and might be more useful for dedicated cat parents.

The height is nearly 28 inches, which might be too tall or bulky for some spaces. The open design means less privacy and can potentially allow some odor to escape compared to fully enclosed boxes, which some cats might prefer. It’s powered by electricity, so it needs a nearby outlet and occasional maintenance of the mechanics. While suitable for multiple cats, heavy use may require more frequent waste drawer changes. This litter box is a great fit for cat owners looking for a convenient, tech-friendly solution that minimizes odor and scooping, especially in multi-cat households, but it does take up considerable space and requires a bit of setup.
