Why Should You Trust Us?
Over the last three years, we’ve spent a lot of time figuring out what it takes to make a great litter box.
We’ve researched the types of litter boxes available, read hundreds of customer reviews, and performed real-world tests on over a dozen top boxes. We spent over 40 hours testing these litter boxes’ sturdiness, cat-friendliness, and ability to prevent sticking and litter scatter.
In addition to research and testing, we consulted with several veterinarians to get their take on which litter boxes work best and are the most effective for cats.
Based on this extensive research and hands-on testing, we’ve selected the 5 products described below as the best high-sided litter boxes you can buy.
