No more scrubbing dirty cage corners and bottoms! The Critter Box® Washable Cage Liner with Raised Sides makes cage maintenance and cleanup much more convenient. The walled sides of the Critter Box® creates a barrier that keeps all messes contained on top of the liner. You won’t have to worry about messes escaping through the sides or underneath your liner anymore. The liner is super absorbent and has a waterproof bottom to prevent leaks. And with Sweep-EZ™ material, hay and debris can be swept up or shaken out of the liner with ease. When soiled and ready to change, simply throw the liner in the wash to clean it. (We recommend keeping an extra liner or two on hand to switch between washes.)

In love!

These are amazing! I prefer these over the Guinea dad liners. These keep the mess contained and keeps it from getting on my floor. Thank you! Thank you! Cleaning is super easy and they fit in the washing machine.

Comfy cage liner

Have been using this item for 2 weeks now and it's the perfect softness for my guinea pigs paws. It's easy to take out and wash. Definitely worth the price.

Love them but they could use some upgrades

I purchased these from Chewy and I love them. We have 2 that we rotate. I fully expected them to last at least 6 months but they last more like 2-3. The back part rips and I cannot figure out why because I hand wash them. They also get really hard in the corners after washing so many times. If those 2 issues were solved, I would not be looking for any alternatives. These help control odor and they are super easy to remove for cleaning.
