Review on SCENEREAL Guinea Pig Cage Liners - Plaid Pet Bedding & Litter, Highly Absorbent Pee Pad for Guinea Pig Hamster and Small Pets – Durable and Water-Resistant by Pamela Pickett

I use these (12*12) over another large cage liner and they work really well!1. shape - they match petco guinea pig housing perfectly. As a result, all the poop is inside the square pillow protector, making it easy to take out and clean!2. Absorbency - as normal (nothing flows through the floor), I change it as soon as I find it wet3. easy to clean - I use a garden hose (jet mode), 20-30 seconds is enough 90% of the urine and 70% of the feces are in the toilet, so fleece bedding lasts much longer. Small urine pads are good extra bedding (easy to change and wash).
