I bought this a little while ago, but it seems to be too small for my cat, and it only went in a couple of times, so I'm putting it up for sale. It's hardly been used. I think the cat realized it wouldn't fit, or maybe it just put its head in and then backed away and lay down right in front of me. I've been sun-drying it on sunny days. There are no stains, but please understand that this is a used item. Size: Approximately 30 cm wide, 33 cm long (excluding the handle) Entrance: 14 cm wide, 13 cm long Instant purchase OK
