A hamster is not a gerbil. Everyone knows that gerbils hate humans and try to get away while hamsters sit there and are calm. When a gerbil escapes their cage, the gerbil freaks out and runs around. In the meanwhile, a hamster sits down and licks itself. This brings me to my first point.
Hamsters are kind of fat. This is why everyone likes them. They are very slow and like to rest. This makes them easy to hold. Unlike gerbils, hamsters are easy to take care of and spend time with. Hamsters like to sit on you and eat. Gerbils like to eat you and run away.
Gerbils are little rats. Hamsters are plump and more appealing. No one likes rats. No one likes Gerbils. That is all. The end.
