Yes! Multiple cats can use the same Litter-Robot—and each one will have a clean place to go each time, thanks to the automatic cleaning cycle. More cats means more waste, so make sure to empty the waste drawer more frequently. Use this infographic to learn how many units are best for how many cats.
If one of your cats is a kitten or may not weigh 2.2 kilograms, be sure to leave the Litter-Robot switched off or unplugged. When you see your cat has used it, wait about 7 minutes for the waste to clump, then turn it on/plug it in. The Litter-Robot will automatically perform a cleaning cycle (takes about 2 ½ minutes), then turn it off/unplug it again. Continue this semi-automatic mode until your kitten has gained sufficient weight to activate the cat sensor. See Can kittens use the Litter-Robot? above for more information.
