I never thought I'd use my ac but find I love it since I can set it to where I want and not have to freeze.

However, I can totally relate to the heat having suffered for long summers with it for years.

Since I didn't have carpeting, I would mist parts of the floors with cold water for the cats to sleep on. It would dry fast and leave the floor cool. You can do the same thing by just mopping the floor with cool/cold water. Fans blowing also helps.

I've even made ice packs wrapped in towels for the cats to sleep next too.
