An order of mammals having two (rarely four) large incisor
teeth in each jaw, distant from the molar teeth. The rats,
squirrels, rabbits, marmots, and beavers belong to this
order.

Note: The incisor teeth are long, curved, and strongly
enameled on the outside, so as to keep a cutting edge.
They have a persistent pulp and grow continuously.
