Abstract: An animal enclosure assembly having an enclosure with at least one side wall and a bottom wall coupled to the side wall. The bottom wall and the side wall define an interior space for containing an animal. The enclosure defines an air outlet that is positioned adjacent a top of the side wall, and an air inlet positioned below the air outlet. The air inlet is configured to receive airflow such that the airflow is directed transversely across the interior space toward a portion of the side wall in a first direction. The airflow is redirected by the portion of the side wall across the interior space in a second direction that is positioned at an angle with respect to the first direction.
