The fat sand rat (Psammomys obesus) is a terrestrial mammal from the gerbil subfamily that is mostly found in North Africa and the Middle East, ranging from Mauritania to the Arabian Peninsula.[2] This species usually lives in sandy deserts, but may also be found in rocky terrain or saline marsh areas.[3] Fat sand rats are very selective in their diet, only eating stems and leaves of plants from the family Amaranthaceae, more commonly known as the amaranth family.[4] In captivity, fat sand rats can become obese and rapidly develop diabetes-like symptoms when fed the diet typically given to other rodents.[5][6]P. obesus has an average lifespan of 14 months in the wild and 3–4 years in captivity.[3]
