3 Things To Consider For Best Cat Litter For Litter-Robot

cat in the litter robot

Let’s talk a bit about the most important features to consider when shopping for Litter-Robot cat litter.

Type of Litter

Choose a high-quality, clumping brand. It doesn’t have to be clay, but it should absorb well.

Otherwise, moisture will seep to the bottom and get everything sticky.

Low-Tracking and Low Dust

While most brands are advertised as low dust and low-tracking, some are better than others in this regard.

Check the customer reviews to see how much dust/tracking you’ll have to deal with.


Fragrances can mask the unpleasant odor of cat urine and feces, but they can also make the smell more pungent.

Some cats also avoid their toilet box because they hate certain smells.

Opt for an unscented brand whenever possible or choose a scented brand with a subtle aroma.


Can You Use Any Litter in the Litter-Robot?

In general, you can use any type of clumping litter, as long as it absorbs well and forms hard clumps.

Some types of gel beads and crystals could also work, but don’t use wood pellet cat litter, such as Okocat. 

Can I Use World’s Best Cat Litter with Litter-Robot?

Yes, you can. This brand absorbs well, even though it’s made from biodegradable materials, and customers have used it successfully with self-cleaning cat toilet boxes. 

How Do You Keep Litter From Sticking to the Litter-Robot?

Choose a high-quality, clay-based brand that forms hard clumps and traps moisture on the surface. You can also try a non-stick spray if you keep finding clumps on the bottom. 

Final Word

Self-cleaning litter boxes are a great way to keep your house odor-free, promote good bathroom habits, and reduce tracking.

But it takes time for cats to get used to such a toilet box since it’s noisy. So don’t be surprised if there are accidents. 

The important thing is to pick a brand that your cat is comfortable with and one that clumps well. If possible, go for small bags until you find the one that works best for you. 

All the brands we’ve reviewed are a great choice for an automatic toilet box, but there’s one that stands out among the others. We’re talking about the Boxiecat cat litter.

We highly recommend it as Litter-Robot’s best litter because it absorbs liquid well, clumps on the stop, and is less dusty than most brands. It also eliminates odors and has a pleasant texture.
