10 Best Automatic Cat Litter Boxes 2025 in the United States

The Litter-Robot 4 Supply Bundle by Whisker is a well-designed automatic cat litter box ideal for households with up to four cats. It features a large, medium-sized unit (27 x 24.25 x 29.5 inches) that can comfortably accommodate multiple cats weighing at least 3 pounds. The standout feature is its self-cleaning mechanism, which uses a patented sifting process to separate waste from clean litter, eliminating the need for daily scooping. This can save you time and reduce unpleasant odors, especially with included OdorTrap refills and carbon filters that further help control smell and litter tracking.

The unit is WiFi-enabled and pairs with the Whisker app, allowing you to monitor litter and waste levels in real time, track your cat’s weight, and control the cleaning cycle remotely. This is a handy feature for staying on top of litter maintenance and your pet’s health without frequent manual checks. It works with any clumping litter, providing flexibility in litter choice. While the Litter-Robot 4 is relatively heavy at 24 pounds and requires a firm, level surface for best accuracy of its weight sensor, it offers a user-friendly setup and maintenance experience. The waste drawer liners and cleaning wipes included in the bundle enhance ease of upkeep. Noise levels during the cleaning cycle are generally low but can vary depending on placement.

Its size may be too large for small spaces, and the initial cost is higher than standard litter boxes. Also, cats under 3 pounds cannot use it safely in automatic mode, which may exclude households with kittens or very small cats. The product comes with a 1-year warranty and is assembled in the USA, which may appeal to those valuing domestic manufacturing. The Litter-Robot 4 represents a reliable, tech-savvy solution to reduce litter box chores and odor, making it a suitable choice for busy households with multiple cats and owners who appreciate remote monitoring and maintenance convenience.
