At 34.8 x 19.5 x 9.8 inches, this litter box is unmatched in size by virtually any other litter box on the market. The company says that the box can contain 30+ pounds of litter, but customer reviews indicate that you may be able to fill up this box with 65 pounds or more.

This litter box is over 9 inches deep, so it’s big enough to contain plenty of litter without excessive scattering. The lowered front side allows kittens and cats with mobility issues to access the litter box.

To help control those multiple cat odors, the litter box features an antimicrobial coating. This Microban coating also helps to prevent staining.

Note that this litter box features a convenient side caddy designed to contain your litter scoop, trash bags, and other accessories. On the negative side, this caddy takes up space that could contain litter. At the same time, having a multiple cat home can leave you frazzled and you can use all the organizational tools you can get.


  • One of the biggest boxes on the market
  • Open box design is multiple cat-friendly

  • The caddy takes up space that could be used for litter containment
