10 Best Automatic Cat Boxes 2025 in the United States

The Litter-Robot 4 Supply Bundle by Whisker is a well-designed automatic cat litter box that offers a convenient self-cleaning solution for cat owners. It uses a patented sifting process to separate waste from clean litter, which means you don’t have to scoop manually—just empty the waste drawer when it’s full. This model is medium-sized, measuring about 27 x 24 x 29.5 inches and weighs 24 pounds, so it will require sufficient space in your home. It runs on power and can be connected via WiFi, allowing you to monitor litter levels, see activity, and even track your cat’s weight through the app, which is a nice feature for health monitoring.

The unit is compatible with any clumping litter, giving you flexibility in choice. It also includes odor control with OdorTrap refills and carbon filters, helping reduce smells and litter tracking around the house. Safety sensors ensure the box operates correctly and is designed for cats over 3 pounds, supporting up to four cats, making it suitable for multi-cat households. Cleaning is straightforward since it comes with liners and wipes to maintain the waste drawer and the unit itself.

Given its relatively large size and weight, it might be a consideration if you have limited space or need to move it often. For optimal sensor accuracy, it needs to be placed on a firm, flat surface, not carpet. The price might be on the higher side, but the bundle includes several supplies to get started. If you're looking for a hands-off, smart litter box that manages odor well and suits multiple cats, this product is a strong choice.

The Litter-Robot 3 Connect by Whisker is a medium-sized automatic litter box designed to make cat care easier by eliminating the need to scoop waste manually. Its dimensions (about 24 x 27 x 29.5 inches) make it suitable for most indoor cats, especially households with up to four cats weighing at least 5 pounds each. The box uses a patented sifting process that automatically separates waste from clean litter, storing the waste in a drawer that you only need to empty when full, which helps reduce odors especially with the included carbon filter. It works with almost any clumping cat litter, giving you flexibility in choosing a product that suits your cat's preferences or your budget.

Powering the unit requires a plug-in source, which means it needs to be near an outlet. The design emphasizes ease of cleaning by allowing simple removal of the waste drawer and accessible parts for maintenance. An added convenience is the ability to monitor and control the litter box using the Whisker app, which notifies you when the drawer needs emptying and tracks your cat’s litter habits, helpful for spotting any health changes early. Safety-wise, the unit has sensors to ensure operation only when the cat is safely inside, but it cannot be placed against walls or in corners as it needs room for the cleaning cycle to function properly.

Priced at a premium, it comes with a one-year warranty and is assembled in the USA. While some users might find the size large or the need for a constant power source a drawback, for those wanting a hands-off, tech-friendly solution that reduces odor and mess, the Litter-Robot 3 Connect stands out as an excellent option.

The PetSafe ScoopFree OpenSky automatic litter box is designed to make cat care much easier by eliminating the need for daily scooping. Its large, sealed 8.5-liter waste drawer can hold up to two weeks of waste from a single cat, which is great for busy owners or those with multiple cats. The box is roomy enough to comfortably accommodate cats of all sizes, and its open-top design helps reduce anxiety some cats feel with enclosed litter boxes.

A notable feature is the advanced odor control; the sealed drawer plus built-in deodorizer work together to keep unpleasant smells to a minimum. The self-cleaning mechanism activates only after your cat has left, ensuring safety and comfort. You can also monitor your cat’s weight and litter usage through an app, which is handy for tracking your pet’s health—just keep in mind it requires a 2.4 GHz Wi-Fi connection. This box works with any type of litter, offering flexibility, but the included liners and fresheners add convenience.

The unit runs on a power adapter and weighs nearly 30 pounds, so it’s fairly sturdy but can be a bit bulky for small spaces. Cleaning this box is simplified thanks to the removable waste drawer and litter mat, although some users might find the initial setup and app connection a bit technical. This litter box is well suited for owners seeking a hands-off, hygienic solution that keeps cats comfortable and health-aware, though those without reliable Wi-Fi or limited space might want to consider those factors before purchasing.
