Its hot here with high humidty. I took out half a cold watermelon and cut it up. Boy, they could not eat the chunks fast enough when I threw them in. I already have a fan outside the run, but I may end up putting a cold wet sponge in front of it. I did put a shallow pan with cold water and ice cubes, but they dont like the idea too well. And forget the hose, they hate the water hose.
