This is a bottom pet heater from Petshop Kojima. Convenient double-sided use. * Highly efficient special wiring heater and built-in thermostat for excellent energy-saving effects. * The cord can be easily replaced if your pet chews on it. *Replacement cords are sold separately. 【 Size 】 W33 x D28 x H1cm I received this a few years ago when I got a pet, and I tried using it, but my pet didn't seem to like it and stopped using it right away. There is some minor wear and tear, but it's generally in good condition. There are no odors.
