When evaluating extra-large high-sided litter box options for this post we were on the lookout for the following big cat (and human) friendly features;

  • Must be suitable for use by large cat breeds
  • To be considered “extra large”, litter boxes should be at least 20″ long
  • To be considered “high-sided”, litter boxes should be at least 10″ high
  • All litter boxes should be easy to clean and ergonomically designed
  • Litter boxes must receive consistently high customer ratings and reviews
  • Easy access designs that accommodate cats of all ages preferred

For the purposes of this post, self-cleaning litter box models have not been included.

Other options to consider

If your cat doesn’t like enclosed litter boxes and the high-sided litter box options above still aren’t tall enough for your cat, you might like to consider attaching a litter box pee shield to your litter box for additional height. 

Alternatively, you could “hack” a suitably sized plastic storage container to suit your needs, like YouTuber, Fundamentally Feline has done (linked).
