Jerboas are the bulk of the membership of the family Dipodidae; they are small jumping desert rodents of Asia and northern Africa that resemble mice with a long tufted tail and very long hind legs. The small forelegs are not used for locomotion. In general, Asiatic jerboas have five toes on their hind feet and African jerboas have three; the shapes of their ears vary widely between species. Jerboa fur is long, soft and silky. Diet varies considerably: some are specialist seed, insect, or plant eaters, others are omnivores.

I saw it in Pets Wonderland before... It has a long huge leg!! Kesian them being locked up in a small place   I saw Jerboa in discovery channel before.. They can run really fast! It will make a clear route during their free time and when it is in danger... it will just use the clear route and run really fast for safety. Like highway like that

Hamsters are the best
