This invention consists of an automatic device used in the raising of chinchillas to allow the animals to sand themselves in a bath of sand, and at the same time to clean said sand from the animal feces. The device consists of a stationary, vertical, circular box having a screen therein which rotates on an inner and outer central shafts pinned together when rotation is required. One position of the screen prevents the animal from entering the device, and another position allows the animal to enter and reach the sand. After a predetermined sanding time, the screen reverses itself, scoops up and discharges the animal, and sifts the sand clean of feces, and returns it to its original location. A clutch is provided to allow rotation when the screen limits are reached. Power is supplied manually, or by a speed reduced motor. And the periods and duration of sanding is controlled by an electric timing device where a motor is used. A quick attachment and release coupling is provided for joining several of the devices together.
