Gerbils are active creatures that need a variety of toys to keep them occupied. The owners of these gerbils hung a cleaned out coconut shell by wire from the lid of the tank. As you can see from the video, the gerbils happily jump in an out of their litte hanging shelter. Coconut shells make excellent toys for many rodents, since they are sturdy and good (and safe) for chewing). Just make sure that you clean the flesh out well, boil the shell to sanitize it, and dry it well.
