Buying Guide: What to Look For in an Extra Large Automatic Litter Box
Capacity and Size
The whole point of an extra large litter box is to accommodate multiple cats and reduce the frequency of emptying. Look for a waste bin that can hold at least 10-15 liters, so you can go days without tending to it. Also, consider the drum size and entry height. A low entry is great for kittens and senior cats, while a tall drum offers more interior space for larger breeds.
For example, the Meowant Large Space Automatic Litter Box offers a 106L drum and 9L litter capacity, making it a roomy choice. If you have a lot of cats, you might also want to explore jumbo litter boxes for multiple cats for even more space.
Safety Features
Safety is non-negotiable when you have curious cats. A good automatic litter box should have sensors that detect when your cat is near and pause the cleaning cycle immediately. Look for anti-pinch designs, infrared sensors, and weight sensors that add an extra layer of protection.
Products like the Cumrige and Fumoi models prioritize safety with advanced sensor systems. For a deeper dive into safety, check out smart safety features in multi-cat litter boxes.
Odor Control
With multiple cats, odor control is a top priority. Look for litter boxes with sealed waste bins, activated carbon filters, or deodorizing gels. Some models have a silicone gasket to lock in smells, while others use a multi-layer defense system.
The Happypaw XXXL model features a triple-lock odor control system, while the Meowant uses a sealed bin and deodorizer. If you’re looking for more options, our guide to extra large multi-cat litter boxes covers additional models with strong odor management.

Frequently Asked Questions
How often do I need to empty an extra large automatic litter box?
It depends on the model and how many cats you have. Most extra large litter boxes have waste bins that can hold 10-15 liters, which can last up to 15 days for a single cat and about a week for multiple cats. You’ll still need to top up the litter and do a deep clean periodically.
Are automatic litter boxes safe for kittens?
Most automatic litter boxes are safe for kittens over 6 months old, as long as they meet the minimum weight and height requirements. Always check the manufacturer’s guidelines. For kittens under 6 months, it’s best to use a manual litter box until they’re bigger.
Can I use any type of cat litter with an automatic litter box?
Most automatic litter boxes work best with clumping litter, especially mineral or bentonite-based types. Avoid crystal or silica litters, as they can damage the motor or sensors. Always refer to the product manual for recommended litter types.
Do these litter boxes really eliminate odor?
They significantly reduce odor compared to traditional boxes, thanks to sealed waste bins and deodorizing systems. However, you’ll still need to empty the waste bin regularly and clean the unit to keep odors at bay.
