I'm selling this because I no longer need it. The cover has been washed. This is a hard-type pet hot carpet with a fluffy cover. The cover is hand-washable, and the main unit can be wiped clean, making it easy to keep it in a clean condition. It can be used reversibly with a high-temperature surface of about 40°C and a low-temperature surface of about 35°C. The main unit size is 21cm long x 27cm wide x 2cm thick. The cord uses a metal spiral tube to protect it from pets biting it.
