So I know the solution for my heat problem (an 86 degree - and rising - house with no ac): ice cream and a ten lbs bag of ice for the fish; now I've just got to figure out one for the dogs . . . .
If you've got space in your freezer, take a small bucket or mixing bowl, fill with water, and place some toys or treats in it, freeze, set out for them to enjoy (outside of course!)
I like those ideas - especially the one that is free . I'm thinking it might be time to buy a window ac since this is the 3rd time this year I've had problems with my central air!
