Many years ago Robert Heinlein wrote a book titled The Door into Summer. The title came from a cat in the book who hated northern winters with cold and snow. He would go from door to door in the house looking for the door into summer.
BG has his own version. BG hates getting wet. Sunday was a cold rainy day here. Beeg went to the door doing his peepee dance I opened the door to let him out. As soon as he put his nose out the door it got hit by a BIG rain drop. Beeg turned himself inside out getting turned around and away from the door. About an hour later he was at the door doing his peepee dance. I opened the door. He stuck his head out, got it wet and yanked it back in. Nope, not going out. An hour later, well you get the picture. This time he never even put his head outside, just stood and looked out at the rain, then at me, then at the rain... An hour later he was at the door doing his peepee dance again. I opened the door. He looked out at the rain, looked at me, then bolted out the door. As soon as he finished his business he raced back to the door. I guess the need to pee overwhelmed his hatred of getting wet.
