This is supposed to be for rodents but I got this for my sons bearded dragon. She loves it. I have not been able to hang it yet as the clasps that clip to the cage aren't long enough. When hung on the top of the cage it's very close to the top and our bearded dragon can not climb into it herself. We have to put her into it ourselves. And when she tries to get out herself the has a jump or fall out of this. This is not safe for her. She can hurt herself falling or jumping out. Other than that this is great for bearded dragons to sleep in at night.
