One cat doesn't even seem to notice it. The other cat is deathly afraid of the A/C fan. He just runs outside and meows at the house all day, as if trying to warn us that there's some monster stalking us from above.

Before nightfall, I grabbed him and brought him in to acclimate. No such luck. With all the exits shut, he just took a round robin approach, polling each exit so that he could get out as soon as one opened up. That's pretty methodical for a cat.

I think today he has decided to find a new home, because I haven't seen him since breakfast.
