MoMo is a semi-feral cat that we saved a year ago. He had to have two surgeries and was confined to a large crate for 7 weeks while healing, and refuses to come back in the house. I had bought him a "single" heated cat house for the front porch and he was happy to have it but it was a little snug as he is a large cat. As soon as I put out his "condo" he went into it, moved around with ease, and started to knead the pad. He has not come out yet, even to eat. He LOVES it. It is constructed well and has a much thicker pad than the "single" one
