I got such great help on my last question so, I have decided to post another question. Now that summer is here in Tennessee, I am concerned about the hot weather. It's known to hit 100 or more degrees here. Being covered with fur, I would think my cats feel the heat more than I do...so if I am uncomfortable, they surely must be. How can I tell if my cats are too hot? I keep the a/c between 72 and 75. Is this cool enough? If they are too hot, what is a good way to cool them off? Any help appreciated.
