Review on Paw Inspired Washable Guinea Pig Cage Liners with Raised Sides, Ultra-Absorbent Fleece Bedding for Guinea Pigs, Rabbits, Hamsters & Small Animals - Critter Box, Edge-Protected Pee Pads by Gregory Robinson

I bought this after looking at similarly priced inserts and chose this one because it has sides. The only thing that bothered me when I thought about the paneling was that the pigs would peck in the corners or the droppings would get under the panelling. It doesn't happen with that and I haven't had any negative issues. It's worth the money when you factor in the long-term savings on linens. It washes well although I didn't put it in the dryer. I bought two to make replacing the liner easier and would recommend this to anyone considering a Midwest living space, which turned out to be a good choice too! Daughter's bedroom with them. Very satisfied!
