How can i make my hamster cage more interesting?

Go to your nearest pet store! They have a whole bunch of hamster accessories there like tv boxes they can climb in, sleep in, whatever. They also have sofa accessories where they love to climb, and besides these are adorable additions to your cage and your hamster will love them. Do not put a stuffed animal in there for it may harm your little guy. They do have beds like that, that are soft at pet stores that may help :) have fun with it :D
