Abstract
A pet door including a cammed closing mechanism and a sliding lock mechanism. The cammed closing mechanism returns the pet door to a resting closed position and provides sufficient force to resist opening by normal weather conditions such as wind or a hard rain without the need for additional components such as magnets. The sliding lock mechanism serves to control the ingress and/or the egress of an animal through the pet door as selected by the pet door owner.
