Abstract: An improved litter device having an enclosed housing with an opening sized to permit the passage of a pet through the housing opening. The housing is divided into two separate internal chambers with an opening between the chambers also sized to permit passage of a pet. Configured and sized to cover both openings are flexible closure which allow for selective passage of a pet through each individual opening when deflected. When the closure are undeflected, they remain closed to provide an isolated or "dead" air space between the openings by creating an air lock chamber. A slidably removable tray is sized to be received into a tray opening that extends into the second chamber, and is used for holding litter. A deodorizing agent is preferably secured to the interior of the housing for absorbing odors created by the pet excretions.
