Pet gerbils are small, friendly rodents that make popular pets due to their playful nature and low maintenance needs. They typically weigh around 2 to 4 ounces and have a lifespan of 2 to 4 years. Gerbils are social animals and thrive in pairs or small groups, making them great companions for families. These animals are known for their burrowing habits and enjoy digging tunnels in their bedding. A suitable habitat for pet gerbils includes a spacious cage with plenty of bedding, toys, and a wheel for exercise. They primarily eat a diet of pellets, fresh vegetables, and occasional treats.
