Hey there! My 2-year-old Siberian cat, Odin, is a hefty 15-pounder who's taken to scratching the wall by his litter box instead of covering his waste, often making a mess. This nightly ritual is costing me sleep. The litter box is 20 inches long and 15 inches wide. I'm concerned it's too small for him. Any size upgrade suggestions for a better fit and more restful nights?

You're not alone in wondering if your cat's litter box is more of a squeeze than a sanctuary. Odin's antics—scratching walls and the occasional mess outside the box—are classic signs that it might be time for an upgrade.
The right-sized litter box is crucial for your cat's comfort and can prevent the issues Odin seems to be facing.
Litter Box Solutions for Larger Cats
Cats are fastidious creatures who value their bathroom space.
Unusual behaviors such as relentless scratching at the box's exterior, making a mess outside, or even avoiding the litter box altogether often signal discomfort.
These signs—including not covering feces and a hasty exit, could point to an issue with the litter box's size.
For a hefty 2-year-old like Odin, the standard litter box dimensions described could indeed be too snug.
A space too confined can lead to stress, and a stressed cat might seek out other places—like that cozy rug you love—for relief.
Ensuring your cat can enter, turn around, and exit the box with ease is key to maintaining both their comfort and your shared environment.
Sizing It Right
The general rule of thumb is that a litter box should be roughly one and a half bigger than your cat from nose to tail when extended and just as wide as your cat is long, excluding the tail.
It may seem like a lot, but for your cat’s comfort, upgrading to a larger size is essential.
Considering most domestic cats measure around 18-20 inches (nose to base of tail), large cats would benefit from a litter box that's approximately 28 to 35 inches in length.
Choosing the Purrfect Throne
When shopping for a larger litter box, keep in mind the height of the sides, whether it's covered, and the ease of entry.
Large cats often need more than what the average litter box offers. A box with high sides and a low entry point could be ideal, providing the space they need without making accessibility an issue.

DIY Covered Litter Box From A Storage Bin
If finding the perfect litter box becomes challenging, creating your own from a large storage bin can be a practical and cost-effective solution.
A caveat for many is they aren’t as easy to clean because of nooks and crannies in the design.
If you’d like to try this DIY option, you’ll need a large storage container with a lid.
- Draw a semi-circle shape on the side of the storage container. Depending on your cat's size, you’ll determine how high or low and how large the opening will be.
- For the next step, it’s important to note that you’ll need to use a sharp knife. Therefore, an adult or adult supervision is required.
- Following the semi-circle outline cut into the storage bin with care. Once the entrance is formed, smooth any rough edges to prevent any harm to your cat.
- Line the bottom of the bin with a garbage bag before adding litter. This step is optional but can save time during maintenance.
- Fill the storage container with cat litter and put on the lid. That’s it!
