10 Best Giant Litter Box 2025 in the United States

The Fumoi Self Cleaning Litter Box is designed with large households in mind, offering a spacious 95L capacity that comfortably suits multiple cats. Its tall sides (approximately 25.8 inches high) help contain litter scatter, making it a good fit for cats who tend to dig deeply or are vigorous users. Made from durable polypropylene and ABS plastic, it promises solid build quality and easy maintenance.

One of its standout features is the automated self-cleaning mechanism controlled via an app, allowing you to schedule cleanings and receive alerts when the waste bin is full. This is especially handy for busy owners or those who want to stay on top of litter maintenance remotely. The litter box uses a sealed 15L waste compartment and a washable liner, both contributing to effective odor control and spill prevention. The inclusion of infrared sensors enhances safety by halting the cleaning cycle if a cat is present, adding peace of mind during operation. It also operates quietly, which is ideal for nighttime use without disturbing you or your pets.

The entry has a lid, which can help reduce odors escaping but may not suit cats that dislike enclosed spaces. While the size and automation offer convenience, its weight (over 30 pounds) may make moving or cleaning the unit more challenging. It also requires a 2.4G WiFi network for app connectivity, which could be a limitation if your home network setup is different. This litter box is well suited for cat owners seeking a large, self-cleaning solution with smart features, especially in multi-cat environments, but it might be less ideal if your cats prefer open litter boxes or if you need something very lightweight and portable.

The PetSafe ScoopFree Crystal Pro is a spacious automatic litter box that suits cat owners wanting a low-maintenance and hygienic solution. Measuring about 28 by 20 inches and 6 inches high, it offers enough room for most cats to comfortably enter and move around. Its uncovered design and low side height make it easy for cats of all ages and sizes to step in and out without trouble. Made of durable plastic, the box is designed for easy cleaning since it uses disposable crystal litter trays that can be replaced every few weeks, eliminating daily scooping.

One of its standout features is the crystal litter, which excels at odor control by absorbing urine and drying solid waste quickly. This helps keep your home smelling fresher compared to traditional clay litter. Additionally, the crystals produce minimal dust and don’t track much on your cat’s paws, reducing mess around the house. The box also offers leak protection thanks to a plastic lining, keeping floors safe from spills. The automatic rake system cleans waste into a covered compartment, minimizing your contact with litter and waste. It even includes sensors and a health counter to monitor your cat’s litter box habits, which can be helpful for spotting early health issues. However, this convenience requires using only the ScoopFree premium crystal litter, which may be more expensive and less widely available than regular litter options.

Weighing 16 pounds, the unit is relatively easy to move but is designed primarily for indoor use and cats up to 15 pounds. Its self-cleaning feature and odor control make it an excellent choice for busy cat owners or households with multiple cats. For those seeking an automatic, low-tracking litter box that controls odors effectively and reduces daily chores, this box performs well, provided users are prepared to use the specific crystals it requires.

The PETKIT PuraMax 2 is a large, automatic covered litter box designed especially for multi-cat households or bigger cats up to 18 lbs. Its spacious interior (24.4" x 21.18" x 21.73") and low, wide entrance make it easy for cats of various sizes, ages, or mobility levels to enter without trouble. The sides are tall enough to help contain litter and mess, while the ABS plastic material is sturdy and simple to wipe clean.

This model stands out for its smart safety features: multiple sensors stop the cleaning cycle if a cat is inside or nearby, preventing accidents. Controlled via an app, you can monitor your cats’ litter box usage and get alerts when cleaning or waste bin emptying is needed. The waste bin is sealed tightly and combined with an automatic deodorizing spray to keep odors under control, which is great for indoor use. The anti-leakage design, including silicone seals and a special brim, helps contain urine and reduces cleaning chores.

It offers about 15 days of scooping-free use for one cat, thanks to a 7L waste bin that is compatible with all clumping litters. However, this litter box isn’t suitable for very young kittens under 6 months or cats outside the 1.5 to 8 kg weight range, so it may not fit all cat families. Also, it must be placed on a flat, solid floor to avoid sensor issues — carpets and mats can cause malfunctions. The PETKIT PuraMax 2 represents a strong choice if you want an automatic, large-capacity litter box with smart features and effective odor control. It’s especially useful for households with multiple or larger cats, though you should consider the weight limits and placement instructions for best results.
