Hmm. Have noticed a pattern in where the cats are napping. It’s 80s-low 90s outside and low 70s in the house due to the A/C. The cats are either on the bed or chair nestled on a blanket, sleeping on a window sill (only if the window is partially open), and one is napping at the top of the stairs. So they are going for insulation warmth of a spot in the house that is 5-6 degrees warmer due to the hot air moving around.
