The teeth of rodents and rabbits grow throughout their lifetime. In order to regulate thie tooth growth, these animals gnaw everything they find : wooden boards, vegetables and even the bars of their cage. This is a need for them, an instinct. If rodents or rabbits found nothing to gnaw, their teeth would grow and they would no longer be able to eat and dental abscesses would appear. Place the stone in the animal's cage. Make sure that the stone is not in contact with the water from the drinking bottle and the animal's urine.
