Gerbils, Gerbils are great pets. Because of their size and affordability, gerbils are an obvious choice for first time pet owners. Gerbils come in a variety of colors, but usually have white fur on their belly. Their tails are covered with hair, unlike those of mice.
Gerbils usually live for three to four years.
Most are nocturnal, but Mongolians are not. All gerbils are very frisky, and can easily escape from a cage that isn't closed securely. Their eyesight isn't very good, so they sometimes fall off of tables when they are running around loose, but their hearing and sense of smell are both very acute. Gerbils must be treated gently, so children interacting with them should be supervised by an adult. Housing Gerbils should be kept in a wire cage or a 10 gallon aquarium that has a wire mesh top.
