Our cage liners are made of high quality fleece fabric on the top layer, soft and spongy wadding in between and waterproof layer at the bottom. The bottom layer is 100% waterproof. However, the sewing process around the liner might allow small quantities of liquids through. This product is suitable for C&C cages. Suitable for guinea pigs, rabbits, ferrets, chinchillas, mice, rats, hedgehogs etc. Washing instructions: Washable at 30 degrees only. No tumble dryer, no fabric conditioner or softener. Due to shrinkage after washes, our liners are made slightly larger on each side. IF YOU NEED A CUSTOM SIZE THAT IS NOT LISTED HERE PLEASE REQUEST A CUSTOM ORDER MADE TO YOUR EXACT SIZE.
