Hamsters and gerbils are both small rodents commonly kept as pets, but there are several key differences between the two:
-
Size: Hamsters are generally larger than gerbils, with hamsters averaging around 4-7 inches in length, while gerbils are usually around 4 inches long.
-
Tail: Gerbils have long, tufted tails that are longer than their bodies, while hamsters have shorter, furry tails.
-
Behavior: Gerbils are more social and do well when kept in same-sex pairs or groups, while hamsters are usually solitary animals and may fight if housed together.
-
Lifespan: Gerbils typically live longer than hamsters, with an average lifespan of around 2-4 years, while hamsters generally live for 1.5-3 years.
-
Teeth: Gerbils have open-rooted teeth that continually grow throughout their lives and require constant chewing to keep them at a healthy length, while hamsters have closed-rooted teeth that grow at a slower rate.
These are some of the main differences between hamsters and gerbils, but there are also differences in diet, housing requirements, and overall care that potential pet owners should consider before choosing between the two species.
