Litter box furniture is a cabinet with a litter box inside it. The cabinet size on the listing is the outside of the cabinet, and the litter box has to fit the inside, which is smaller.
This guide takes the enclosures and splash guards in the Pet Potty Shop and puts their inside and outside sizes next to each other, along with the entry side and the material.
Prices were read from the store on October 23, 2026 and can change; the product page shows the current price.
Outside size vs inside size
The 23.6 in cabinet is a clear example. Its outside is 23.6 x 19.7 x 21.7 inches and its usable inside is 21.6 x 18.2 x 19.7 inches. The listing itself says to measure a litter box before placing it inside.

Check which side the cat walks in. The 23.6 in cabinet has a reversible side panel for a left or right entrance. The 31 in cabinet has a removable panel that goes on either side, and double cabinet doors with a lock for scooping.
Dividers
The 31 in cabinet has a removable divider. The listing gives a small section of 9.4 x 18.1 in and a large section of 19.7 x 18.1 in. One side holds the litter box and the other helps catch litter before the cat exits. Its title says 31 in long and its description says 31.5 in, so allow for both.

Frequently Asked Questions
How do I know if my litter box fits in an enclosure?
Compare the litter box with the inside size, not the outside. One listing gives an inside of 21.6 x 18.2 x 19.7 inches for a 23.6 in cabinet, and another states boxes up to 12.2 x 20.87 in.
Can the entrance be on either side?
On some cabinets. The 23.6 in cabinet has a reversible side panel for a left or right entrance, and the 31 in cabinet has a removable panel for either side.
What is the difference between an enclosure and a splash guard?
In these listings, enclosures are cabinets with panels and doors, while splash guards are open walls around the box, some with a removable mat.
