Review: Worth it. - If the price has you thinking about the off-brand filters, let me save you money now. These are worth it.

Finally bought these from Whiskers which, unlike the others - are thick and fit the slot perfectly. No more odor — they work perfectly and are worth the cost!

## Questions & Answers

**Q: Does Litter-Robot require special litter?**
A: Litter-Robot simply requires clumping litter. 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.
