We recommend a high-quality, standard-weight, clay-based clumping litter. Some silica gel litter beads and crystals can also be used with Litter-Robot, as long as they pass through the screen. **Q: How many cats can use Litter-Robot?** A: We recommend up to 4 indoor cats per single Litter-Robot; however, we do have customers with more cats using a single unit. Litter-Robot 4 features an enlarged waste drawer for even more waste capacity, which means emptying is required less often. **Q: What if my cat won't use Litter-Robot?** A: If you and your cat are not completely satisfied, just return your Litter-Robot within 90 days of purchase for a full refund of the purchase price. **Q: Does Litter-Robot have a weight limit?** A: No, Litter-Robot does not have a weight limit. Size and weight often have little to do with whether a cat will adopt Litter-Robot or not. Whether or not Litter-Robot will be comfortable for a large or fat cat is up to the individual. **Q: How often do I need to empty the waste drawer?** A: With Litter-Robot 3, once every 10-12 days per one cat is usually sufficient; two cats, twice per week; three cats, every other day. Litter-Robot 4 has an enlarged waste drawer, so you may not need to empty the waste drawer as frequently. ## Frequently Bought Together - Litter-Robot 4 Carbon Filters by Whisker, 12 Pack, Custom Fit Carbon Filter Pads for Litter-Robot 4, Absorbs and Reduces Litter Box Odors for Cleaner Smelling Home - OdorTrap Pack Refills by Whisker, 12 Pack Refill for OdorTrap Pod (Pod Not Included), Eliminates Litter Box Odors, Compatible with Litter-Robot & Traditional Litter Boxes, 8.96 Fl Oz - Litter-Robot Waste Drawer Liners by Whisker, 100 Pack - Litter Box Liner Bags, Custom Fit for Litter-Robot, 9-11 Gallons of Capacity --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/679884275-whisker-litter-robot-4-carbon-filters-6-pack-custom-fit](https://www.desertcart.us/products/679884275-whisker-litter-robot-4-carbon-filters-6-pack-custom-fit) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-19*
