How wonderful! I've noticed all my dogs and and cats over the years love to hang out by me when I'm using my red light and they also tend to bask in the sun coming through windows. They seem to instinctively seek out the light. My fawn colored boxers in particular loved to sunbathe. My darker furred dogs would tend to stay in the shade more-probably because they would get too hot if they were in direct sunlight for too long.Ah yes. Mr. Phineas seeks out the red light on his own. These snaps were during the winter in Chicago.
