K&H Thermo Mod Cat Shelter vs Aivituvin AIR12 Heated Cat House

The Aivituvin AIR12 is the sturdier long-term outdoor shelter: insulated wood, an asphalt roof and a raised floor hold warmth and shrug off weather better than a fabric house. The K&H Thermo Mod is lighter, cheaper to run at 25 watts, and easier to move, clean and set up, but its polyester shell and vinyl backing wear faster in sun and rain. Buy the Aivituvin for a permanent spot on a porch or in a yard; buy the K&H if you need a portable, low-power shelter or a backup for a garage or barn.

• Choose the K&H Thermo Mod if you want a lightweight, portable heated shelter for a garage, barn or covered porch and you value easy cleaning and low power draw.
• Choose the Aivituvin AIR12 if the house will sit outdoors year-round and you want wood construction, a raised floor and an asphalt roof to keep the heat in.
