I'm wondering how much warmer summertime temperatures matter to cats. I'm not the kind of person who enjoys air conditioning on high at all. I have one unit in the main part of my apartment, and a ceiling fan in my bedroom. Normally during the summer if it's over 90, I will keep the a/c on 73 or so while I'm gone and if it seems too warm when I return, I'll lower it a bit. Is that too warm for Luciano? I don't want my electricity bill to go out of control & my apartment is usually quite breezy.
