The cats sleep on the bathroom floor--I guess it's the coolest place.
I sleep with a damp towel and a fan blowing on me (air conditioner keeps blowing the damned fuse :P )
The fuzzies get sprayed with a water bottle. Reiko likes it, Skip, not so much. Unfortunately, ferrets really can't deal with heat waves without help.
And Chris... well, he stays up late enough that it's not quite so hot any more when he goes to bed. :D
Can we all pray together for a little cool air?
