A '''hopping mouse''' is any of about ten different [[Australia]]n native mice in the [[genus]] '''''Notomys'''''. They are [[rodent]]s, not [[marsupial]]s, and their ancestors are thought to have arrived from [[Asia]] about 5 million years ago.

All are brown or fawn, fading to pale grey or white underneath, have very long tails and, as the common name implies, well-developed hind legs. Half of the hopping mouse species have become extinct since European colonisation. The primary cause is probably predation from introduced [[Red foxes in Australia|fox]]es or [[Feral cats in Australia|cat]]s, coupled with competition for food from introduced [[rabbit]]s and hoofed mammals. A hopping mouse's primary diet is seeds. An Australian hopping mouse can concentrate urine to as high as 10,000 m[[Osm/L]] (10-20 times higher than a human). This allows it to survive in the desert without drinking water.
