Far-infrared heater to keep your pet comfortable. - Type: Far-infrared pet heater - Maximum temperature: 40℃ - Minimum temperature: 35℃ - Power consumption: 8W - Size: 1.8m I bought this about a year ago and only used it in a cage when I had a puppy. I no longer need it, so I'm selling it. I have confirmed it works at the time of listing. I have another one of the same item, so you can purchase two. Please comment if you'd like to do so. Thank you for looking.
