CatGenie SideWalls Review

The CatGenie SideWalls give your cat the privacy your pet needs when doing its business. The SideWalls are 4” tall adding extra inches to the CatGenie rims, which helps to contain the kicked litter inside the litter box, reducing litter scattering.

The SideWalls are seamless and fit snugly onto the CatGenie base, matching the same color, Pearl Gray. The sides give the CatGenie a cool human toilet look.


  • CatGenie SideWalls provide your cat extra privacy
  • It helps to contain litter scattering
  • 4-inch sides helps to contain urine or feces from “accidents”
  • Provides benefits of a hood for cats that don’t like deep cover
  • Seamless sides match CatGenie’s Pearl Gray base
  • Named Global Pet Expo 2007’s Best New Cat Product
  • Dimensions: 16.2” x 12.4” x 4.2”



To install the CatGenie SideWalls just slip the sides right onto the base, it’s very easy and no assembling is needed. The ends go under the topper on the back.

The SideWalls feature a lower entry for the cat’s easy access to the litter box. Also, the rims feature small holes to assemble the CatGenie Dome in case you purchase this item.



  • Very easy to install
  • It fits nicely on the base of the CatGenie
  • It looks neat with the CatGenie, matching the color perfectly
  • The SideWalls make the unit look like a human toilet
  • It helps to contain kicked litter
  • It reduces the use of granules so you can save some money
  • Helps to contain urine or feces from going outside the litter box



  • If you purchase the SideWalls you need to buy the Dome separately (see tips)
  • The SideWalls accessory is 4” tall but as it rests on the base of the CatGenie, it only adds 2 1/2” over the actual rim.
  • Heavy diggers still scatter some litter when digging or jumping in
  • To cut down most of the litter spillage you must use the SideWalls together with the Dome
  • Even using the SideWalls your cat may carry granules on its paws onto the floor
  • The SideWalls accessory has holes that don’t look very nice if you don’t use it with the Dome.



If you really want to contain the litter mess and help your cat having less litter box “accidents” you need to purchase the Dome instead of only buying the SideWalls, because the Dome comes with the SideWalls in a set, but buying the SideWalls as single accessory means you will have to buy the Dome separately.



The CatGenie SideWalls work as described. This accessory doesn’t really raise the edges in 4” but only on 2 1/2” but this extra height still helps to reduce litter scattering if your cat is not a professional litter kicker.

I recommend this accessory to stop the granules from going onto the floor but if you really want to cut down most of the granules spillage and keep your cat’s butt on target, you need to buy the Dome that comes with the SideWalls.

On the other hand, if your cat is large I don’t recommend buying the Dome, hence, the SideWalls.
