Gerbils are able to perceive human speech. Researchers from the University of South Alabama experimentally found that these mice can distinguish sounds in the same way as babies do.
When gerbils are given a treat, they often wink with one eye. This can be regarded as a sign of gratitude and pleasure from eating.
If the gerbils feel danger, they begin to bang their hind legs. And males produce a similar knock even at the moment of mating.
Gerbils get along well with other small animals, in particular with rodents, and when they meet with their relatives they touch their noses. So the animals say hello.
Gerbils can purr with pleasure, like a cat. More precisely, you will not hear a sound, but you will feel a characteristic vibration. However, these pets moo only when they really like to sit on the hands of a man.
Unlike other rodents, gerbils never bite people unless they see a threat to their lives in their actions.
Gerbils live about 4 years, but already in the 3rd year the animals show signs of aging.
