A motor vehicle window cage that fits into and extends through a motor vehicle opening that allows a pet to safely place it's head through the window opening when the motor vehicle is moving or parked. The cage is made up of a mesh-like material with a top mesh surface, two side mesh surfaces, and a front mesh surface. Formed on the cage is a rear opening and a bottom base. The bottom base acts as a shelf that allows the pet to stand in the seat and rests its front paws on the shelf. The cage is designed to confine the animal inside the motor vehicle yet allow the window to be extended downward to provide fresh air. The cage component can be easily attached and detached from the motor vehicle with two sets of adjustable straps that extend around the door's upper and lower frames without modifying or alternating the motor vehicle.
