A side panel of the enclosure is provided with an aperture and a cover flap substantially larger than the aperture is secured along three sides to the side panel with the fourth side having an elastic to hold the edge of the flap against the side panel. The ends of the elastic may be detachably secured to provide a non-elasticized opening during training of the pet.
