K&H Thermo Mod Cat Shelter vs K&H Outdoor Heated Kitty House

Both are K&H heated outdoor cat houses with insulated walls and a MET-listed heated pad, so the choice comes down to size and door design. The Thermo Mod is the larger, taller shelter with a single wider opening and a 25-watt half-floor heater, which suits bigger cats, community cats and small dogs. The Outdoor Heated Kitty House is the more established model, rated 4.7 from 269 ratings, with a 20-watt Lectro-Soft bed, a preset thermostat and two exits with clear flaps. Buyers who want a roomier house with more heat output lean Thermo Mod; buyers who want the proven, better-reviewed two-door design lean Kitty House.

• Choose the K&H Thermo Mod if you have a large cat, a feral colony or a small dog, and want the taller house with the stronger 25-watt heater and a single wide entrance.
• Choose the K&H Outdoor Heated Kitty House if you want the long-reviewed two-exit design with a preset thermostat and clear door flaps that keep heat in and give a cat an escape route.
