Cherry, whom is about 5 or 6 years old, is my favorite pet. About three years before, Cherry showed up at our house. I have just lost my cat and was very sadly, so I didn’t plan to own another pet. At first, we ignored her. We were getting ready leave for a vacation. My two daughter kept wanting us to keep her and fed her behind my back. Finally I had to tell them if he was still here when we got back, we would keep her. I was sure a dog would move on. Guess what? When we got back from vacation, but the dog was still around. It seemed like an angel had send her to us.
