Sorry Nomilynn - we don't get HOT weather here - when it occassionly reaches the high 70's - we all moan that its 'too hot'!!
But all my cats love ice cubes in their water when it is hot - we don't have a water fountain yet. I'm going to pick one up when I'm in the States in October!!! They are much cheaper over there!!!!
And they all enjoy being wiped down with a towel rung out in cold water.
Sorry I can't be of more help.
