Cute pictures!
We have red squirrels, not gray. We accidently caught one in a pack rat trap and it lost a front leg but survived so we named it Tripod. While I enjoy watching them, I like them to stay further away from the house or I am reminded that they are really rodents by what they leave behind.
We had an albino squirrel. It lived two years that we know of, and raised a litter. The biologists at the university said it was a rare thing.
