I do the same with my ducks. I have to make sure their pool gets cleaned and filled in both the mornings and evenings on hot days and it’s killing me. My one duck is disabled and she has trouble cleaning herself all the way, so she gets sprayed off with the hose once a day. The birds are doing really well in the heat, which has been a relief. My dogs have been just as miserable as I have been. My cats seem fine.
