Mine is from vetfleece on ebay, they have two types - greenback is denser and can be washed at very high temperatures so is great for veterinary use, and the non slip is more grippy and comes in more colours, you can wash it at 40 and it's really easy to cut up to the required size. It's beautiful stuff, so so soft but my boys pee all over it. It's got brilliant drainage so keeps them really dry and seems to stop smell coming through, so when i first put it in I left it for a few days thinking they'd been using their litter tray, but it was absolutely soaked underneith :shock: So if you do get it, check underneith regularly and put puppy pads or newspaper under
