"I like these tubes a lot for any small pet. They are a lot of fun inside and outside of cages. I found two elbows on clearance for $2 at Petco, so I decided to try them out on my hamster. When Roho is out of his cage, he likes to climb up the tubes. I can tell that this is made for MUCH larger animals, but it works fine for my dwarf hamster. I may be getting a guinea pig soon, so I will give this to him instead."
