Hamster Fact: Hamsters are burrowing animals. They have very strong front arms and weaker back legs. They mainly use their legs for propelling themselves forwards and their strong arms for digging. This makes them very acrobatic. They can also climb the bars of their cages and hang on very well! If you have hamsters, make sure you give them something to dig in like lots and lots of bedding. They will love you for it.
