The American beaver is North America's largest rodent.

This animal has very prominent front teeth (central incisors), generally stained an amber color, which are always growing and must be used consistently to keep them trimmed back.

Female beavers are believed to be monogamous whereas some think males may breed more than one female. Gestation is 90-100 days and the female generally gives birth to 3-6 young. Kits born in the family will usually only stay for about 2 years before setting out to establish independent adult lives.
