Our Thermo‐Kitty Furniture Warmer is the perfect addition to any piece of cat furniture. We incorporated straps to hold it in place on any platform while the flexible design conforms to nearly any tunnel or hammock. The gentle warmth stays slightly above room temperature to entice any kitty and when in use, quickly warms to your pet's normal body temperature. Our time tested 4 watt heater even incorporates an extra long cord for ease of use and is extremely safe and energy efficient. Thereʹs no doubt your feline friend will appreciate a new favorite warm spot to snooze. Recommended for indoor use. One year limited warranty.
