Unfortunately, my cat didn't use this, so I'm putting it up for sale. I had it out for about a week, but she didn't use it much, so it's clean. It comes with a cover, and a spare cover for washing. I removed the hair with a lint roller, but couldn't get it all off perfectly. Please understand this before purchasing. It's convenient because you can leave it on all the time. The size is 40x50cm, suitable for cats and possibly medium-sized dogs.
