Small Animals. Did you know?

Did you know that rabbits have teeth that just keep growing?
Rabbits have four front teeth, incisors that continually grow. These teeth, two on the top, two on the bottom are ground down by certain foods, and chewing on hard objects like wood. Rabbits will then sharpen their teeth by bruxing, or grinding their teeth together. Rats, mice, gerbils, and guinea pigs have the same teeth.
