This insulated cat house, crafted with 2-layer fir wood and thermal liner walls (plus full roof/floor insulation), locks in comfortable temperatures year-round. Its large door with PVC curtains blocks cold wind and rain, while the wave tile roof ensures all-weather protection for winter warmth and summer shade. With 19.5"L x17.5"W x12.8"H interior space (fits cats from kitten to adult), pre-drilled holes for easy assembly, and an openable roof/removable panel for simple cleaning, it works perfectly indoors or outdoors.
