How Well do Hamsters See, Hear and Smell?

How Well do Hamsters See, Hear and Smell?

Recognizing that hamsters have a different range of senses to humans will help you understand your hamster better. Some of the limitations or amplitude of your hamster’s senses will affect their behaviour, and if you know this, you will not be puzzled or frustrated by your pet’s behaviour. It can also keep your hamster safe.

Hamster Eyesight

Hamsters have very poor eyesight. Hamsters are born blind, and as adults, they can only see a few inches in front of their noses. This makes them unable to tell when they are in danger of falling because they cannot see that far. For this reason, cages with several levels are not recommended. Hamsters cannot tell when the floor drops off, and they could fall from an upper level. This can cause broken bones, internal injuries and even death. It also means that you should not let your pet perch on your shoulder or hold him while you are standing – again, they can fall or jump, resulting in serious injury or death.

Hamster Hearing

In contrast to their poor eyesight, hamsters have an extraordinary sense of hearing. They can hear and communicate with each other using frequencies that humans cannot hear. Hamsters will often freeze when they hear an unusual sound, then sometimes sniff the air for more information. Because a hamster has such keen hearing, you must speak softly to your pet and make sure your hamster is not kept in a noisy area of the house. Do not allow other pets to make loud noises around your hamster. Barking dogs, in particular, can cause extreme stress for your hamster. Children should be taught not to be loud or squeal around your hamster, as well. Hamsters have delicate ears that can easily tear. Be sure to be gentle with your pet’s ears, and make sure they are not injured in fights with other hamsters.

Hamster Sense of Smell

Your hamster uses his sense of smell to recognize other hamsters, to tell whether a hamster is male or female, to find food, and also to detect pheromones in hamster social situations. Hamsters communicate with each other using pheromones (chemicals that are secreted from the body). Male and female Syrian hamsters mark their territory with scent glands located on their hips. Sometimes the fur around these glands is a slightly different colour. Because their sense of smell is so keen, make sure your hands are clean when handling your pet. Scents on your hands can either make your pet agitated or want to nibble you. (Hand washing before and after handling your hamster also helps prevent the spread of disease.)

Do not allow cats to lie on your hamster’s living quarters. The cat’s scent will cause stress for your hamster.

As a general rule, remember that your hamster’s eyesight is poor, and his other senses are more enhanced in order to compensate.
