When choosing between a hamster vs gerbil as a pet, understanding their distinct characteristics is crucial. While both are small rodents popular in the pet trade, they differ significantly in social needs, activity patterns, and care requirements. Hamsters are solitary creatures with a lifespan of 2-3 years, while gerbils are social animals living 3-4 years and requiring companionship.
