For the price, I believe this is the best product on the market for your outside kitties and ferel visitors. You cannot build a equivalent house for less. I purchased the heated kitty house. Wasn't sure I would keep it but was thrilled when it arrived. This house is exactly as described and completely contained once put together. A five year old could assemble it. Well thought out design and wished I'd thought of it. Worth every penny and is a must buy.
