Aivituvin Outdoor Feral Cat House vs Insulated Two-Story Cat House

Buy the Aivituvin if you want a bigger, sturdier wooden shelter with two PVC flap doors and a large window, and you can accept a roof that is not insulated. Buy the Insulated Two-Story if warmth matters most: its 0.78-inch foam liner covers six sides and its roof opens for cleaning. Owners of both report long assembly times and occasional cracked or misaligned panels, so check the parts before you build. The Aivituvin has more ratings and a slightly higher score; the insulated house has fewer ratings but answers the cold-weather job better.

• Choose the Aivituvin if you need a roomy wooden two-story shelter with a large window, a jumping platform and two flap doors for a porch or backyard.
• Choose the Insulated Two-Story if you live somewhere cold and want a removable, washable thermal liner on all six sides plus an openable roof for cleaning.
