This is a pet hot carpet with a washable fleece cover. I purchased it two years ago and used it only in winter, placed under the cages of small animals, so pets did not directly touch it. There are no noticeable signs of use. Operation has been confirmed. The heater and power cord are protected to prevent pets from biting. A thermostat is located inside to regulate the temperature, keeping the carpet at an appropriate temperature and cutting down on unnecessary power consumption. The surface of the main unit has two sides: a high-temperature side (approx. 38°C) and a low-temperature side (approx. 28°C). Surface material: Vinyl chloride resin Connection box: ABS resin Cover surface material: 100% polyester Cover backing material: Non-woven fabric Product weight: 700g
