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.)

You and your small animal will love the Critter Box®. Not only does it make cleanup easier for you, it’s also made of dust-free velvet fleece so your pet will stay comfortable and safe within its home. Not only great for guinea pigs, the Critter Box® can also be used for ferrets, rabbits, rats, bunnies, hamsters, dogs, hedgehogs, chinchillas, birds, and other small animals. The Critter Box® liner fits perfectly in most top-selling guinea pig and small animal cages and habitats. Our current sizes are designed for the C&C coroplast 2x3, 2x4, and 2x5 cages, as well as MidWest cages.

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.

Awesome Pawsome!!!

This is my fourth critter box! It makes clean up a breeze (use their disposable liners on top), exceptional quality and customer service!

Paw Inspired® Critter Box® Washable Guinea Pig Cage Liner with Raised Sides

Tina Palmer
Makes Cleaning Cages So Easy

These pads are custom made to fit C&C Cages perfectly. The Critter Boxes have raised sides which keep even the most active guinea pigs from throwing their hay, food and poo outside of the cage. The box bottom is waterproof and keeps water and urine from leaking out. The highly absorbent liners fit inside the boxes, and both boxes and liners are covered with a quilted brushed cotton. This makes them so easy to clean because nothing sticks to them. I can clean them with a brush. My old fleece pads had to be vacuumed to remove hay and food bits. They are also machine washable. I can clean my cages very quickly now and can spend more time petting my fur babies. Paw Inspired will soon have them available for Critter Nation cages, too. I will definitely be buying more.

I have bought all of the sizes for my piggies because I have some in C & C cages and in the Midwest cages all products are AMAZING! I've even bought some for my grown kids piggies for their homes. We are a guinea pig family and these products are the best! So EASY to clean, absorbent, and extra cushiony for our fur babies feet! I'm a forever customer!
