Buying Guide: What to Look for in a High Sided Litter Box

Choosing the best high sided litter box involves more than just picking the tallest option. You need to consider material, entry height, ease of cleaning, and durability. Below are the key criteria we used to evaluate the Yangbaga XXL.

Material: Stainless Steel vs. Plastic

Stainless steel is the gold standard for litter boxes because it does not absorb odors like plastic does. Over time, plastic boxes develop microscopic scratches that trap bacteria and smell, even after thorough cleaning. The Yangbaga XXL uses a single piece of stainless steel with a non-stick surface, making it far easier to keep fresh. It also resists rust and staining, so it looks new for years. If you have ever dealt with a plastic box that needed replacing every six months, this upgrade is worth considering.

Side Height and Entry Design

The whole point of a high sided litter box is to prevent litter from being kicked out and to contain urine spray. The Yangbaga XXL features 12-inch high sides, which are effective for most cats. However, the entry must be low enough for kittens and senior cats to step over comfortably. This model has a U-shaped entry that is 6 inches high, striking a balance between containment and accessibility. Cats with arthritis or mobility issues can enter without jumping, while the high sides still block messes.

Seamless Construction and Safety

One of the biggest complaints about traditional litter boxes is that urine can seep into seams and corners, creating a stubborn mess. The Yangbaga XXL is made from a single sheet of stainless steel with no seams, so there is nowhere for liquid to hide. Additionally, all edges are rolled inward, eliminating sharp edges that could cut your hands or your cat’s paws during cleaning. This attention to safety makes it a great choice for households with multiple cats or curious kittens.

Frequently Asked Questions

Are high sided litter boxes good for senior cats?

Yes, if the entry is low enough. The Yangbaga XXL has a 6-inch high U-shaped entry that is easy for cats with arthritis to step over. The high sides still contain messes without forcing your cat to jump. Always pair a high sided box with a non-slip mat for extra stability.

Do stainless steel litter boxes smell less than plastic?

Absolutely. Stainless steel is non-porous, so it does not absorb urine odors like plastic does. The Yangbaga XXL’s non-stick surface also makes cleaning easier, reducing the buildup that causes smells. Many users report that their box stays odor-free between cleanings.

How do I clean a high sided stainless steel litter box?

Simply dump the litter, rinse with water, and scrub with a mild detergent or stainless steel cleaner. Because there are no seams, you can easily reach every corner. The rolled edges prevent scratching your hands. For deep sanitizing, use a vinegar solution or a pet-safe disinfectant. Avoid abrasive pads that could scratch the surface.

What size litter box do I need for a large cat?

The Yangbaga XXL measures 24 inches by 16 inches with 12-inch high sides, providing ample space for even the largest cats to turn around and dig. If your cat weighs over 15 pounds, this size is ideal. For extra-large breeds, consider a box with even more floor space, but this model works well for most households.
