We do not have good luck with our pets. This time I really thought we had picked the right one. But tonight we discovered Luke had passed away in his cage. The tears came, then the questions why. I do not have an answer. I do not know why a guinea pig would die. We fed him. We kept clean water. We did everything they said to. We held him and played with him. My sons heart is sad tonight. He kept crying and saying "I don't even have a picture of him". I wish now I had tried harder to get a picture of him that day. Something to remind him of Luke. He has already asked me for another pet. What am I going to do?
