He's cold with the AC on in Mid August. He's always under the blankets, I make him wear a sweater but his ears still get cold from the AC....even when I don't have it on and its sweltering here, he is cold...but their bodies are crazy warm, weird, he leans against me in bed and I break out into a sweat. They're really cool (not temp wise )cats, very attached to their people, smart and loveable.
