A rabbit’s teeth never stop growing due to their unique composition.

In the realm of lagomorphs, rabbits stand out for their teeth, which exhibit a perpetual growth mechanism. Unlike human teeth with enamel, rabbit teeth comprise cartilage and bone. This distinctive dental structure prevents excessive wear, allowing rabbits to gnaw and chew continuously. This adaptation is not just a quirky feature but a crucial aspect of their biology, ensuring their teeth remain functional throughout their lives.
