A gerbil is a small, burrowing rodent that belongs to the family Muridae. Native to Asia and Africa, these animals are often kept as pets due to their friendly nature and low maintenance needs. Gerbils typically have a long tail, large eyes, and soft fur, which can come in various colors. In the wild, gerbils live in social groups and create complex tunnel systems. They are primarily herbivorous, feeding on seeds, grains, and plants. As pets, they require a suitable habitat, such as a cage with bedding, and enjoy activities like running on wheels and exploring tunnels.
