Cuddly, soft, pretty. There are two round Öffnungen.Meine bitch is 4kg heavy and has a lot of space in the cave. The reason for "only" 4 stars is the extreme smell of the cave at the furnace opening of the package. It smells "chemically" by color or by some synthetic (similar to nail polish or nail polish Terner. My dog is gone purely only after 5 days. After about 4 or 5 days in the "open air" it is odorless. But then an oasis of peace for my dog.
