Some interesting facts about hamsters are that they have the ability to run backwards just as quickly as they can run forwards, this is because of the size and shape of their feet. They can actually see better in the dark than in the light as they are nocturnal and are adapted to scavenging and burrowing in the dark.
Hamsters are colorblind, 97% of their eye cells are “rods” which cannot capture color. But the “rods” cells are what allows them to see during the night. They have monochromatic eyesight, they see everything in a single color. With hamsters they are very short-sighted, seeing only a little past their nose. They rely on other senses like hearing and smell, with hearing they can hear higher frequencies than humans and will often communicate in the higher frequencies with each other. As part of their anatomy they have scent glands that will leave a scent allowing them to navigate, find food, and protect themselves.
