adding one of these to a climbing tube will keep your rodents active and happy. they love climbing the tubes and even find ways to get the bedding up to the "attic"

Pros: all gerbils or hampster need to climb and hide

Cons: none

I had hamsters as a kid. We had a set up that took up an entire room. We had several of these. I loved to watch them climb up into the towers. These things were just cool.

Pros: Great hide aways for hamsters

Cons: none

This was my hamster's favorite spot to sleep. He used to carry mouthfuls of his bedding up there so that he could make a cozy little alcove. He'd also hide a lot of his food up there, as well.

Pros: Great spot to sleep, easy to clean, entertaining

Cons: None
