Pros
- Exceptional safety with multiple sensors that stop cleaning when cat is inside
- Large waste capacity means less frequent emptying, perfect for multi-cat households
- Quiet operation won't scare cats or disrupt your home
- Easy setup and maintenance according to user reviews
- Spacious top entry accommodates cats up to 22 lbs

The Mimfam Automatic Self Cleaning Litter Box (model AS11) is designed for cat owners who value convenience and safety. It suits multi-cat households and those with larger breeds, thanks to its spacious top entry and generous 10L waste container. This self-cleaning box automates scooping, freeing up your time while keeping the litter area fresh.
Standout features include four pairs of infrared sensors and three hall sensors that halt the cleaning cycle if your cat re-enters, ensuring no accidents. The 10L waste bin holds up to 10 days of waste for a single cat, reducing daily chores. User reviews praise its quiet 32dB operation, which keeps cats calm and homes peaceful.
The open-top design is well-received for reducing litter tracking and providing easy access. The polypropylene build is durable and easy to clean, though some users note the sensors can accumulate dust over time, requiring occasional wiping. The included litter mat and liner bags add value, making setup straightforward.
Drawbacks include the front button placement, which cats may accidentally press, and the cost of replacement waste baskets. A few users mention that the sensor dust film can cause false stops, but regular maintenance solves this. Despite these issues, the overall feedback is highly positive, with many calling it a lifesaver.
Verdict: The Mimfam AS11 is a reliable, safety-focused automatic litter box that excels in multi-cat homes. Its large capacity, quiet operation, and robust sensor system outweigh minor design quirks. If you want to stop scooping daily and prioritize your cat's comfort, this is a solid investment.
Buying Guide: What to Look for in a Self Cleaning Litter Box for Large Cats
Size and Interior Space
Large cats need room to turn around, squat, and dig without touching the walls. Look for a globe or open tray with a wide entrance and ample diameter. The Furrykiddy model boasts a 65L globe, while the FEELNEEDY offers a semi open design that many shy cats prefer. Measure your cat’s length from nose to tail and compare with the product dimensions. A cramped box can discourage use and lead to accidents.
Safety Features That Protect Big Cats
Automatic mechanisms must stop immediately if a cat re enters during a cycle. All three products we reviewed include multiple sensors: infrared, weight detection, or motion sensors. The Ellenpent model uses both infrared and weight sensors for double assurance. For households with kittens or very large cats, a dedicated kitten mode (like on the Furrykiddy) lets you disable automation entirely until the cat reaches a safe weight.
Odor Control and Waste Capacity
A large cat produces more waste, so a bigger waste drawer means fewer changes. The FEELNEEDY box holds a 10L drawer (7 10 days for one cat), while the Furrykiddy offers a 12L sealed bin. Look for layered odor locking systems: carbon filters, scented gels, or sealed compartments. The Ellenpent model uses an integrated ABS material that traps smells at the source.

Smart Features and App Control
All three models connect via 2.4GHz WiFi to a smartphone app. You can start a cleaning cycle remotely, monitor usage frequency, and get alerts when the waste bin is full. This is especially useful if you travel or work long hours. The FEELNEEDY app also tracks health metrics like bathroom frequency.

Final Thoughts
After evaluating each model for large cat suitability, we recommend the Automatic Litter Box Self Cleaning from FEELNEEDY for its open design, robust safety sensors, and app based health tracking, making it ideal for cats that dislike enclosed spaces. For budget conscious owners with multiple large cats, the Automatic Self Cleaning Litter Box from Furrykiddy offers a spacious 65L globe, quiet operation, and a large waste bin at a more accessible price point. Both models deliver reliable automation while keeping your big feline comfortable and your home fresh.

Frequently Asked Questions
Can self cleaning litter boxes handle very large cats over 18 pounds?
Yes, but you need to check the weight limit. The Furrykiddy model supports cats up to 18 lbs, while the FEELNEEDY and Ellenpent boxes accommodate cats up to 18 lbs as well. For cats heavier than that, consider an open tray style or a box with a larger entrance. Always measure your cat’s weight and length before purchasing.
How often do I need to empty the waste drawer for one large cat?
With a 10L to 12L drawer, you can go 7 to 15 days depending on the model and your cat’s output. The Furrykiddy 12L bin lasts up to 15 days for one cat. The app will send a full bin alert so you never have to guess. For multi cat households, you may need to empty every 4 7 days.
Are self cleaning litter boxes safe for large cats that like to jump in during cleaning?
Absolutely. All three models have safety sensors that stop the mechanism immediately if a cat enters. The FEELNEEDY uses multi directional sensors, the Ellenpent uses infrared and weight sensors, and the Furrykiddy uses weight detection with a dedicated kitten mode. These features prevent pinched paws and ensure your cat stays safe.
Do these litter boxes work with clumping, crystal, or tofu litter?
Yes, all three are compatible with clumping, crystal, and tofu litter. The Furrykiddy model explicitly supports these types. Avoid using non clumping clay or very lightweight litters that may not separate properly. For best results, follow the manufacturer’s recommendations.
