A device is described that provides a stabilizing platform for a domestic pet animal that contributes to the safety of the animal when it occupies the interior of a motor vehicle. The stabilizing platform can be placed on the interior side wall panel which contains a window in a motor vehicle, thereby allowing the pet to place its feet on the top surface of the platform so that the pet can look out the window or place its head out a partially opened window while increasing the pet's stability and safety. Furthermore, the use of the stabilizing platform aids in the safety and comfort of the motorist and passengers.
