With yesterday's heat the main part of my house was about 90°F but
the bedroom (in the foundation) was 70°. When I went to bed, Tiger
came downstairs but Amber stayed upstairs. Not too bright!!!

Well, you must remember that a cat's normal body temperature is about
101.5, not the human 98.6. That extra couple of degrees means that when
we are too warm, cats are probably most comfortable.
