Give your feline friend a cozy retreat from the cold with this thoughtfully engineered heated cat house, designed to provide safe, consistent warmth in any season. At its heart lies an 18W waterproof heating pad that raises the interior temperature by up to 20degree(s)C / 68degree(s)F-enough to turn a chilly winter day into a snug sanctuary. Built with intelligent safety features, including power failure protection, an over-temperature cutoff, and over-current safeguards, the heating system runs continuously with complete peace of mind. (Note: The pad takes about 10 minutes to warm up-just enough time for your cat to settle in.) The interior is lined with thermal insulation materials, including aluminum foil and pearl cotton, that reflect and retain heat, while a soft blanket adds an extra layer of belly-warming comfort. The rugged 600D Oxford cloth exterior features a waterproof Pvc coating on all six walls, and a Pvc curtain at the entrance blocks moisture and drafts
