We always leave the AC on for ours. I used to worry about the same thing, but have never had a problem, so I'm getting a little more relaxed about it. Of course, we don't all leave at the same time for very long, so that is good.
We also leave the TV on for them. I don't think they care what channel it is, just so it makes some noise. I've heard people say they leave it on Animal Planet, but ours don't seem to care. |
