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

Buy the Aivituvin if your cat needs active heat: it is the only one of the two with a thermostat-controlled, UL-certified heating pad and a removable insulated liner. Buy the Petscosset if you want passive insulation and easier cleaning: six-sided insulation, an openable roof and a removable floor and divider. Build is comparable wood construction, but owners of the Petscosset report cracked panels, misaligned side gaps and a back panel with no latch, while the Aivituvin's 4.2 from 175 ratings is a broader track record than the Petscosset's 4.3 from 10.

• Choose the Aivituvin if your winters are hard and you want a heated pad plus a washable insulated liner in a compact footprint.
• Choose the Petscosset if you want full passive insulation, an openable roof for cleaning and a layout you can reconfigure for more than one cat.
