10 Best Giant Litter Box 2025 in the United States

The Cumrige Self Cleaning Litter Box is designed with large cats and multiple-cat households in mind, thanks to its generous size (26"L x 20"W x 21.6"H) and a high-capacity drum that can hold up to 95 liters of litter. Its sides are tall enough to help contain messes, which is useful if your cat tends to kick litter around. Made from durable plastic materials (Polypropylene and ABS), it feels sturdy and easy to wipe down. A major plus is its automatic cleaning function, which activates only when no cat is inside, providing a safe experience for your pet.

The built-in odor control and sealed waste bin help keep smells at bay for up to 15 days, cutting down on frequent maintenance. You can even control and monitor the litter box through an app, which offers useful alerts and health tracking, though note it only works with 2.4G WiFi. The entry is open-topped without a lid, making it easy for cats to get in and out quickly, but this might allow some odors to escape compared to covered boxes. Its quiet operation means it won’t disturb your home’s peace.

This litter box is ideal for cat owners seeking a hands-off, hygienic solution with tech features, especially suitable for larger or multiple cats. However, the reliance on specific litter types and the need for app connectivity might be a slight hurdle if you prefer simpler setups.

The PETKIT PuraMax 2 is a large, automated self-cleaning litter box designed to handle multiple cats or bigger cats up to about 18 pounds. It offers a roomy interior with dimensions of roughly 24 x 21 x 22 inches, making it comfortable for larger pets. The sides stand tall enough to help contain litter and mess, while the low 7.8-inch entrance is a smart choice for older or less agile cats, reducing entry stress. Made from durable ABS plastic, this litter box is built to last and easy to wipe down.

What sets this model apart is its advanced cleaning system controlled via a smartphone app, allowing you to schedule or manually trigger cleaning cycles without physically scooping. The device uses a sealed waste bin combined with smart deodorizing sprays and odor eliminators, which work together to keep smells under control for up to two weeks. The inclusion of a silicone-lined roller and waterproof mats helps prevent leaks and litter sticking, simplifying daily maintenance. However, the setup requires placing the unit on a hard, flat surface—as carpets can interfere with its sensors. It also suits cats weighing between 3.3 and 17.6 pounds and older than six months, so it's not ideal for kittens or very small cats. Some users may find the 21.8-pound weight a bit heavy if moving it frequently is needed. While it excludes crystal litters, it supports a wide range of clumping litters.

The PETKIT PuraMax 2 proves to be an excellent choice for cat owners looking for a high-tech, large, low-entry, and mostly hands-free solution to maintain clean and odor-free litter areas for multiple or large cats.

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.
