Interesting point about the power going out and therefore the a/c going out. That did happen to us and our small dog and my son's larger dog was in there all day. Fortunately we were somewhat shaded, but it was very warm in there and we felt horrible. Never thought about the power going out.
My pets are like my kids, which is why I asked this question. I could never forgive myself if something happened to them. My intention was never to leave them in there for more than a couple of hours. Stop to get a bite to eat, or pull in some tourist attraction etc. I am definitely rethinking this and do appreciate all of your opinions and warnings. I really thought this would be the answer. Now that we are retired and can travel, we can't so to speak. I would NEVER EVER give them up so I was looking for a solution.
