K&H Outdoor Heated Kitty House vs New Age Pet ECOFLEX Outdoor Cat House

Buy the K&H if you want warmth built in and a house you can move and wash. Buy the New Age Pet if you want a rigid, heavier shelter that will sit outdoors year-round and you plan to add your own heat pad. The K&H ships with a Lectro-Soft heated bed and two flap doors, and its hook-and-loop walls go up without tools; owners rate it 4.5 from 472 ratings. The ECOFLEX is a wood-plastic composite box with a raised floor, a sloped roof and a 5-star average from 164 ratings, but it weighs about 20 lb and needs a separate heated pad for real winter warmth.

• Choose the K&H Outdoor Heated Kitty House if you have two or more cats, a porch or barn, and want heat and wind-blocking flaps included out of the box.
• Choose the New Age Pet ECOFLEX if you want a sturdier, longer-lasting structure with a raised floor and don't mind adding your own heated pad.
