Kirsten-

Do you have any of those ice packs that take forever to melt? If so, place it in a small towel, and let the kitties lay on it, it will cool them down.

My vet told me to do this, years ago when I had an outdoor kitty hanging around (was the neighbors, but was always at my house ) Pumkin just loved sitting on her cool bed. I had 2, and that seemed to be enough to last through the day.

You know, this can also help humans out too!
