Clawsable Tall Classic Box Heated Cat House vs Aivituvin Insulated Cat House L-A with Liner

Buy the Clawsable Tall Classic Box if you want active heat and a raised platform for wet, snowy ground. Buy the Aivituvin if you want passive insulation and a wooden build that holds warmth without power. The Clawsable runs a fixed 131°F pad and holds up to three cats, but owners say the pad runs continuously and the house is light in wind. The Aivituvin's six-sided liner and asphalt roof need no electricity, but it is smaller, needs assembly, and carries only a 30-day warranty.

• Choose the Tall Classic Box if your winters are cold and wet and you want a heated pad plus a raised floor that keeps cats off snow, mud and standing water.
• Choose the Aivituvin if you have no outdoor power, want a wooden house with a removable liner for year-round use, and can assemble it.
