This is the only pet car seat that is heated to provide cozy, warm quarters for pets during travel. A 12-volt heater inside the seat cushion produces a mild radiant heat up to 15º F above the ambient temperature that warms pets yet is not hot to human touch. The seat cushion is filled with 3" of soft, supportive foam and the interior of the car seat is covered with smooth, plush fleece. The two included adjustable 19" leashes attach to a metal D-ring inside the seat to keep pets safely restrained while allowing freedom of movement. A car's seat belt can be strung through the base of the car seat to keep it stable when driving. The heating element plugs into a car's DC outlet with the included adapter. For pets up to 35 lbs. Tan. 16" H x 23" W x 18 1/2" D.
