7 Extra Large Litter Boxes That Can Fit Your Large Cat

7 Extra Large Litter Boxes That Can Fit Your Large CatWhether because you got a larger breed or your cat’s a little overweight, you own a pretty big kitty. Nowadays, when they try to wriggle into their litter boxes, it doesn’t really work. They can’t squeeze into the opening very well. Once they get inside, they have no room to maneuver or move around.

For those reasons, they may have even eschewed their litter box altogether. This creates a major problem for you since you now have to clean up kitty messes around the house. You need something bigger and better for your cat.

The extra large litter boxes we found on Amazon should suit you just fine. These giant boxes were made with bigger kitties like yours in mind. With generous measurements (more than 22 by 17 by 5 inches) and spacious openings to boot, your cat should no longer struggle to get into and out of their box. That means they’ll go back to making waste in there instead of doing it on your carpet.

Not sure if you should size up your cat’s litter box? We wrote a great guide on proper litter box sizing for your cat. Here’s a recap of when it’s time to upgrade:

  • Your cat spreads litter outside of the box because there’s just not enough space for it inside.

  • They’ve begun making waste around the house when they’d previously used a litter box with no issue.
