For kitties, it's like insulation; keeps them cool when it's hot, keeps them warm when it's cold. Cot is just ridiculous! I've found him sitting in front of the air outlet for the mini split, with the cold air ruffling his fur and he sleeps under the wood stove with a 900 degree fire inside of it! I've warned him of spontaneous combustion, but does he listen? Anyway, kitties are unique! Love ya much!🤗😘🌸💖
