I live in the country and I have a huge, lush lawn. We do not use pesticides on the lawn. I was thinking about making a little play-pen outside so Oliver can explore the great outdoors. Is it okay to let your piggie play outside, as long as you are supervising? I know piggies are succeptable to heat stroke so it would have to be in the evening on a cool day, and I would bring his hidey huts out with me. What does everyone think of this?
