Abstract: An automobile litter box includes an enclosed volume open at one end which provides a receptacle with a base which is curved and adapted to rest on the outer periphery of an automobile transmission and drive shaft tunnel. A pair of arcuate arms are rotatably mounted at opposing ends of the base and adapted to engage the outer periphery of an automobile transmission and driveshaft tunnel. Means are provided for applying spring-like compressive force to at least one of the arms thereby providing frictional compressive engagement of the arms with the outer periphery of the tunnel.
