The cotton outer body of this fair-trade, artisan-made animal is filled with acrylic and rice, so the pet may be used as a heating pad after placed in the microwave for a very short period of time. Velcro on the bottom of the animal enables washing of the cotton body and acrylic inside. The uncooked rice is separate, in a bag. Caution: When heating, please carefully check the temperature prior to giving it to a child. Launch date: May 20, 2007.
