The term "sand rat" commonly refers to the gerbil, a small rodent native to Asia and Africa. These animals are known for their long tails, large eyes, and soft fur. Sand rats are typically found in arid environments, where they dig extensive burrow systems to escape the heat and store food. Sand rats are primarily herbivorous, feeding on seeds, grains, and roots. They are social creatures, often living in groups, and are known for their playful behavior. Due to their adaptability, sand rats have become popular pets, often kept in cages and enjoyed for their friendly nature.
