Size ranges come from a published cat size guide, and individual cats vary. Box count follows the AAHA guideline.

A note for Siberian owners

Long fur can carry litter out of the box, so a mat by the entrance helps.

Will a PetCraft box fit?

Our largest steel box is 24 inches, which is too short for most cats of this breed. A large storage tote is a better fit.
