Outdoor Cat House Weatherproof Insulated Shelter vs Aivituvin Heated Feral Cat Shelter AIR7033

Buy the Aivituvin AIR7033-IN-HP if you want a heated, two-story shelter for several cats through hard winters. Buy the MellowPaws HDPE house if you want a simple, light, easy-to-clean single shelter that goes together in minutes. The Aivituvin is bigger, heavier and better insulated, with a thermostat-controlled pad rated 95–113°F; the MellowPaws relies on a hollow double-wall shell and a round burrow entrance. Owners rate the Aivituvin 4.5 out of 5 from 13 ratings; the MellowPaws has no comparable rating record, so its long-term durability rests on the maker's 3+ year claim.

• Choose the MellowPaws HDPE house if you want a low-effort, wipe-clean shelter for one or two cats and don't need power at the site.
• Choose the Aivituvin AIR7033-IN-HP if you have several cats, a cold climate and an outdoor outlet for the heated pad.
