I used this for my puppy for three days, but ultimately didn't use it and am now selling it. It has been cleaned and is free of stains, but the cord has a small bite mark in one place, so the condition is listed as "slightly scratched or with some stains." Please check the damage in the 8th photo. I think it won't be a problem if you make sure the cord can't reach out of the cage when you use it. Size: M (45 x 45cm) 【30-level Temperature Adjustment - Warm in Winter】Our pet heater allows for fine temperature adjustments in 30 increments, from 30 to 60°C. Pets can comfortably spend time with the optimal temperature setting depending on the season and usage environment. The pet heater heats evenly once the temperature is set. If the temperature of the main unit drops below the set temperature, it will automatically heat up again. Pets can comfortably spend time with the optimal temperature setting according to the cold days and changes in temperature. 【Convenient 12-level Timer Function】The pet hot carpet can be set with a 12-hour off timer, and the heater mat will automatically turn off when the time is up, which helps prevent you from forgetting to turn it off. If you want to use it continuously without setting a timer, you can set the timer to "00". 【Overheat Protection, Waterproof, and Flame Retardant】The pet heater has a built-in overheat protection device to prevent high-temperature combustion, and the power will automatically turn off in case of overheating or voltage abnormalities. It will automatically heat up again when the temperature drops. It has built-in flame-retardant cotton to achieve even heating and more effectively reduce risks. The surface uses environmentally friendly medical-grade PVC material and has an IP67 waterproof design to prevent the risk of electric shock from urine or water seeping in. 【Full-body Spiral Tube for Cord, Washable Cover Included】The power cord is protected by a durable stainless steel protective tube, and the stainless steel spiral tube and tube reinforcement at each connection prevent the cord from being chewed, protecting your pet from the danger of electric shock. High-quality crystal microfiber fabric is used, and the fluffy feel is soft. If the product gets dirty, you can remove the cover and keep it clean.
