10 Best Large Cat Litter Boxes 2025 in the United States

The Fumoi Automatic Litter Box is designed with large households or multiple cats in mind, featuring a spacious 95-liter capacity. Its generous size (about 22 x 20 x 26 inches) comfortably fits bigger cats and helps reduce litter scatter. Made of durable plastic materials (polypropylene and ABS), it ensures sturdy use and easy cleaning. The hooded design aids in containing litter and odors more effectively than open boxes.

A standout feature is its self-cleaning function controlled via a smartphone app, allowing scheduling of cleanings, receiving alerts, and monitoring litter levels remotely. Safety sensors pause cleaning when the cat is inside, enhancing pet security. The removable, washable liner and sealed waste compartment contribute to less messy and more hygienic cleanup. Additionally, a quiet night mode keeps noise low, minimizing household disturbance.

However, the box is quite heavy (over 30 pounds), which might make it harder to move around, and it requires a 2.4G WiFi network for app control, which could be limiting for some users. Its large size means it will take up considerable space in the home, and the price plus tech features may exceed the needs of casual cat owners. For multiple-cat homes or those seeking a hands-off cleaning experience with advanced features, this litter box is a solid choice. Simpler options might be better suited for single-cat households or budget-conscious users.

The PetSafe ScoopFree Crystal Pro is a large, open-style cat litter box made from plastic, designed to simplify cleaning with its automatic self-cleaning feature. It uses disposable crystal litter trays that absorb urine and dehydrate waste, which helps control odors better than traditional clumping litter. Its low-tracking, dust-free crystals reduce mess outside the box, making it a good choice for keeping your home clean. The box measures about 28 by 19 inches, providing ample space for most cats up to 15 pounds, and the entry is open, which some cats prefer for easy access.

One of its standout features is the health monitor with motion sensors that track your cat’s litter box habits, potentially helping spot health issues early. The disposable trays with leak-proof liners protect floors from spills, adding to its convenience. However, the box is designed exclusively for use with PetSafe’s crystal litter, which could be a drawback if you prefer other litter types or find the crystals costly. Also, the open design lacks a hood, so it may not contain odors or litter dust as completely as hooded models.

Cleaning is simplified since the box rakes waste automatically and requires only tray changes every few weeks, cutting down on daily scooping. The upfront cost and ongoing need to purchase special trays might not fit every budget. This litter box suits cat owners seeking a low-maintenance, odor-controlling solution who don’t mind using a specific litter type. It may be less suitable for those wanting a fully enclosed design or more flexible litter options.

The Pawstastic Self Cleaning Litter Box is designed for large cats and multi-cat households, featuring a roomy interior (about 23.6" x 20.9" x 60" height) that comfortably fits cats up to 24 lbs. Made from durable ABS plastic, it is waterproof and easy to clean. The litter box includes a hooded design with an automatic self-cleaning mechanism controlled via an app, which reduces the need for daily scooping and manages odors through a built-in exhaust fan.

Equipped with multiple sensors, the box ensures your cat's safety by pausing the cleaning cycle if a cat is inside. It tracks your cat’s weight and toilet habits via the app, which is useful for health monitoring, especially in busy households with up to five cats. The large 10L waste compartment allows for up to 15 days of use without emptying, ideal for pet owners who travel or have tight schedules. It supports all types of clumping litter and includes features to prevent litter or waste from sticking, helping maintain cleanliness. The device operates quietly, suitable for bedrooms or quiet areas.

The tall height (60") might be challenging in tight spaces, and the app’s monitoring may be less accurate if cats have similar weights. While the setup includes extra trash bags and mats, the unit is relatively heavy (33.7 lbs), which could make moving it tricky. This litter box is a good fit for owners seeking a hands-free, tech-savvy solution for multiple or large cats and who want to keep odors under control with minimal daily maintenance. However, it may not suit those with limited space or those preferring a simpler, non-automated box.
