We recommend having no more than four cats to one Litter-Robot unit. The 3-minute setting sure comes in handy here! For these instances, you’ll want to minimize the amount of time cat waste is exposed to the open air. (We’re looking at you, Sphynx cats!) Likewise, litter box odors are much more obvious in a small space such as a bedroom or studio apartment. Some kitties have stinkier waste than others. If you have a very “stinky” cat or live in a small space: 3 minutes Setting the Litter-Robot Wait Time to 3 minutes effectively prevents most dogs from nosing out a “snack” in the litter box. With the Litter-Robot, it’s much easier to prevent your dog from “indulging” by minimizing the amount of time the cat waste is exposed. It’s a fact of life in a shared pet household: Many dogs eat cat poop. However, there are a few specific scenarios where you may benefit from decreasing the Wait Time setting to 3 minutes or increasing to 15 minutes. Many Litter-Robot customers will find that the default Wait Time setting of 7 minutes works well for their pet household. Which Wait Time setting should you choose? The Wait Time is a timer countdown function, or the elapsed time starting from when your cat exits the Litter-Robot globe until the unit starts a Clean cycle. But which Wait Time setting is right for you? As if this weren’t amazing enough, cat parents can choose the Litter-Robot Wait Time to determine how soon a Clean cycle begins after their cat exits the unit. How did the engineers at Litter-Robot solve “the litter box problem?” With a patented sifting process that uses a combination of time, rotation, and gravity to automatically separate your cat’s waste from the clean litter.
