It ain't the heat
Today's the first day in a while we've been able to sit comfortably inside with the windows open. It's not that we've been belted with ridiculously high heat, but, at the risk of evoking a cliche, it's been the humidity.
Enough so that we've kept the house hermetically sealed with the window AC units going full blast.
A few days ago we got a little break from it and we turned them off and opened up the windows. We were all okay, except for the cat, whose girth and heavy coat still made it uncomfortable for him.
He was lying on his side in the living room, looking like a lion baking in the sun of the African savannah, when he decided he'd expose his belly to the air to radiate more heat. Up went one paw, then the other, and he began to arch his back as if to roll onto it.
After a moment he decided that it just wasn't worth the effort and collapsed again on his side, letting out a resigned snuff.
