This fleece liner is amazing, honestly! I've had it several weeks and it keeps smells down, it's so easy to brush poop and litter off of each day, and it washes so well. The best thing about it is it fits the XL cage with Cavy Bistro SO perfectly. Nothing gets under it on the sides and it makes changing the cage super easy. I have a similar type product from Amazon, and it is about half as thick and not nearly as absorbent. I wish I had just saved my money on that one and bought two of these since that's what I ended up doing anyway. I love this product, get two for cage cleaning and you will be set for a long time!
