I was going to say that birds need changes more often because of 'fowling' ;-) it, or bathing it out. Same with the chickens when they don't use those drinkers.
Us, too. We have been drinking a lot more water recently, and still have to be careful of dehydration at these temperatures.
Sleeping during the day during really hot weather is not a bad idea. It's siesta time in a lot of places. But, they have those lovely thick walls, and wooden shutters. It is really cool in some of those homes!
Stay as cool as you can!
