I have a "pet" Eastern Grey Squirrel that we found as a baby, nursed her back to health, and then released her into the backyard. She comes to visit every day or so and eats a bunch of walnuts and pecans, plays a little while, then goes back to the trees. We've built her a "squirrel house" that she sleeps in when it's cold. Sometimes I can actually go into the backyard and call her to me. When friends that don't know see me do that, they think I'm Dr Doolittle LOL.
