<p>Described is an animal door for providing an animal a passageway through a structure and for reducing thermal transfer through the passageway. The animal door defines the passageway, which is sufficiently large for the animal to pass through, and is adapted to be secured to the structure such that the animal can pass through the structure by passing through the passageway. The animal door includes at least three flaps disposed at the passageway. The flaps are constructed and configured to reduce thermal transfer through the passageway by reducing both thermal convection and thermal conductivity at the passageway.</p>
