Best Auto Litter Boxes for Multiple Cats – A Complete Guide

A good quality auto litter box can make all the difference in keeping your cats happy and healthy.

Yet, with so many litter boxes on the market, finding the perfect product for multiple cats can take time.

This guide will explore the best auto litter boxes for multiple cats, features to look out for when purchasing one, and tips to keep your litter box clean and well-maintained.

Factors to Consider When Purchasing Auto Litter Boxes for Multiple Cats


If you have large cats, purchase a larger litter box. Your cats will be more comfortable using it. Additionally, you’ll help prevent odors from building up quickly as the waste in the tray will disburse efficiently.

Size of the Waste Receptacle

If you have a litter box with a larger waste receptacle, you won’t need to empty it frequently, which is a plus if multiple cats share it.


Smart Features

Smart features like Alexa and Google voice assistants can make for a hassle-free operation of your litter box. Again, this is key if multiple cats use the litter box.

Self-Cleaning Time

How long does it take for the litter box to self-clean? I prefer less self-cleaning time for a litter box that serves multiple cats. That way, you’ll experience a reduced odor build-up.

Adjustable Cycle Timer

Some litter boxes for multiple cats have an adjustable cycle timer, and you can schedule the cleaning time based on your preferences. That is handy if you don’t want the litter box to self-clean itself.

Cat’s Adaptability

A litter box for multiple cats should be adaptable for the kitties. For example, it should be self-cleaning and remain fresh for the next cat’s use.

Also, it should be large enough for waste to distribute itself evenly inside the tray.


Self-cleaning litter boxes can be noisy due to the sifting process. So, buy a product with an almost noise-free motor.


Go for a litter box that suits your budget, provided it meets the needs of your cats. It’s not wise to spend more than what you can afford.

Whether You Need to Buy Custom Parts

Most self-cleaning cat boxes need you to purchase custom parts, including disposable litter trays, waste liners, and cleaning solutions. That is an ongoing cost you should consider in addition to the price of the cat litter box. 

Does It Require a Special Litter?

Some litter boxes, such as custom anti-clumping silica crystal litter, require special litter. Meanwhile, others are compatible with any clay-clumping litter. So, go with what suits your preferences.

How to Acclimatize Your Cat to an Automatic Self-Cleaning Litter Box

Keep It Unplugged Initially

Plugging a new litter box like a plugged vacuum cleaner could scare your cats away. Instead, let your cats get used to the litter box before you plug it in.

Encourage Your Cat to Explore It

Place toys and treats near the new product to lure your cat into exploring it.

Also, you might want to dig into the litter with your hand and see your cats’ reactions – if they’re going to copy you or even sniff the new litter box.

Place It Next to the Old Litter Box

Put the new litter box very close to the old litter box. That might make the cats relate to the two and start using the new product more quickly.

Stop Cleaning the Old Litter Box

Cats like to pee and poop in the clean litter. So, if you stop cleaning the old litter box, your kitties will likely stop using it and start using the new litter box.

Keep the Litter Constant

Use the old litter in the new litter box. Note: some self-cleaning litter boxes will have you use the custom litter, while some will require you to use the hard-clumping litter.

In this case, you can use a bit of new litter in the old litter box to help your cat acclimate to the new product faster.
