Litter Robot 4 Cat Litter Tray - White

Hello Kyle,

After checking with our supplier, they have advised for the Litter Robot 4 Cat Litter Tray - White: ''We recommend a regular weight, clay clumping litter for the best results to ensure your Litter-Robot is functioning at its best. For litter brand recommendations please view our websites blog post.

Lightweight Litter
Lightweight litter does not work well with our weight-based system. The globe requires 8-10 lbs of litter to detect a 5 lb cat accurately. Lightweight litter typically weighs 50% of a standard weight litter, so it may not sense smaller cats.

It may work if the cats are generally heavier (10+ lbs). Also, note that lightweight litter tends to produce more dust and clump more slowly than other litter, so you may need to adjust the wait-time setting.

These litter types also tend to hold onto moisture and can cause corrosion to the metals and wiring inside the base. We'd recommend more frequent cleanings if using this type of litter.

Crystal Litter
Crystal litter (such as Pretty Litter) will work in the unit if the crystals are small enough to pass through the sifting screen. However, translucent or white-coloured litter (most often seen in crystal litter) may impact the litter level and Drawer Full Indicator (DFI) accuracy in Litter-Robot 4. Crystal-based litters will absorb the urine and dry out faecal matter so it will still drop down into the waste drawer. We'd recommend increasing the cycle delay setting to 15 minutes to allow the waste more time to dry out before it cycles. We'd also recommend replacing the litter more often to reduce odours. User experience varies with this type of litter.

Plant-Based Litters (Wheat, Corn, etc.)
Plant-based litter is typically not suitable for Litter-Robot because this litter does not clump well (resulting in litter sticking to the globe liner), decomposes more quickly, and tends to produce more litter dust and tracking. Since these litter types also tend to hold onto moisture, additional odours, gases, and moisture may cause corrosion to the metals and wiring inside the base, resulting in more frequent cleanings.

Pellet-Shaped Litter (Pine, Newspaper, etc.)
Larger pellet-based litters do not sift through the screen and often do not create litter clumps. We do not recommend using these types of litter in the unit.

Other Non-Clumping Litter
Non-clumping litter is not recommended for the unit.

Here are a few things to consider when trying out alternative litter. As long as it's clumping, it will work in the unit; however, the user experience varies based on your cat's waste, diet, health issues, volume, and environment.''

Thank you for using Q and A.
