Hello, Doug. Welcome to BPO.
My Annie (7 years old) is a rescue saint. She came to us this past April, so this will be her first Summer with us. We live in SO. Calif., near the low desert, so we have already had some very warm days since Annie joined us. We have a swamp cooler in our house, and she likes to lay in the hall, directly in the airflow. One day it was very warm (90-95) and I found her napping in the bathtub. It's now her favorite place to nap. As for shaving, I'm not so sure. I did clip her rear leg 'feathers', but that's all. When she's outside, she prefers a shady spot in the cool dirt up against the house. Annie also loves to chew ice cubes. I wish you all the best with rescue. My experience has been wonderful. I am so happy with Annie!! She makes me laugh every day.
