Aivituvin Insulated Cat House AIR12-IN vs Aivituvin Heated Feral Cat Shelter AIR7033

Both are Aivituvin wooden outdoor shelters with six-sided insulation, asphalt roofs, PVC flaps and raised floors, so the build and weather protection are close. The AIR7033 is the bigger two-story unit with a thermostat-controlled, UL-certified heating pad and multiple access doors, which suits several cats or a colony. The AIR12 is a compact single-level box with a removable plush liner and a heated liner rated 89–116°F, better for one cat in a tight spot. Ratings are close (4.6 vs 4.5) on small sample sizes, so treat owner feedback as thin.

• Choose the Aivituvin AIR12 if you have one cat, limited space, and want a simple single-level shelter you can strip down to a bare liner in summer.
• Choose the Aivituvin AIR7033 if you shelter several cats or a feral colony and want two levels, a thermostat-controlled UL-certified pad and doors that make feeding and cleaning easier.
