8. Gerbils have very fast-growing front teeth
While a healthy diet and clean surroundings can help your gerbils stay in good health, you need to pay attention to a few special needs. Out in the wild, they use teeth constantly on tough tree roots as they burrow their way around. In a domestic setting, they have little to chew on. This can result in long, out-of-control front teeth that make life difficult. Giving your gerbils chew blocks doesn’t do the trick, either. Since they have no actual need to chew much, they can lose interest in the opportunity. If you have a dozen gerbils, you need to take time out to take them all to regular visits to the vet to have their teeth ground down. This can be a time-consuming chore.
