The highest-rated self-cleaning litter box

Because waste is promptly removed and contained in the base, typical litter box odors will be significantly reduced with Litter-Robot. Litter-Robot 4 features an optional OdorTrap™ System designed to neutralize litter box odors. This system uses the combination of a sealed waste drawer and carbon filter to reduce odors. You can opt to replace the carbon filter with OdorTrap™ Packs to eliminate litter box odors through natural chemistry. This is one reason why Litter-Robot is a great choice for multiple-cat households.

A self-cleaning litter box offers many benefits for both cats and pet parents by automatically providing a clean bed of litter every time your cat needs to go. Cats naturally prefer a clean place to do their business and if they’re presented with a dirty litter box, they may go outside the litter box or not go at all—potentially leading to a host of health problems. A self-cleaning litter box like Litter-Robot eliminates the need for pet parents to have to scoop, saving time and frustration brought on by an unpleasant chore. Additional benefits include better managing odor control, keeping cats’ paws cleaner, and helping reduce litter usage. With Litter-Robot, you’re not just buying a self-cleaning litter box—you’re getting a better way of life with your cat!

Most cats acclimate to Litter-Robot just fine. The trick is to ease your cat into the transition. We recommend placing Litter-Robot near the old litter box without removing the old litter box yet. Take a cup of litter from the old litter box and add it to the clean litter in Litter-Robot to provide a familiar scent. If you have an increasingly skittish or skeptical kitty, leave Litter-Robot turned off until you know it’s been used. Read more about how to acclimate your cat.

Not at all! Litter-Robot doesn’t need special litter or proprietary consumables like several other self-cleaning litter boxes on the market. In fact, Litter-Robot works well with almost any clumping litter. Litter beads and crystals that are small enough to pass through the screen will also work in Litter-Robot. Litters that are strictly absorbent, non-clumping, loose-clumping, newspaper-based, or wood-based pellets won’t work with Litter-Robot, as they interfere with the sifting process.

Kittens that weigh 3 pounds or more can safely use Litter-Robot 4 in automatic mode, while kittens that weigh 5 pounds or more can use Litter-Robot 3 (with or without Connect) in automatic mode. If your kitten does not meet this minimum weight, leave Litter-Robot off to operate in “semi-automatic” mode. When you see your kitten has used Litter-Robot, turn it on, and Litter-Robot will automatically perform a clean cycle. Once it finishes, turn the power off. This way, your kitten is safe while they get accustomed to Litter-Robot at a young age, and you don’t have to scoop the litter box!
