Any one boarding pets?

We took our four-year-old to Clearwater and Gathering of the Vibes. Since we approached those with the idea that we were taking him to the fests (rather than merely taking him with us), we decided to take in Interlocken on our own. He's pretty much diaper trained, so we're leaving plenty of food and water--in fact, since there's a chance of spillage we're leaving several watering spots around the house as well as plenty of dishes of food.

Oh, we also have three cats. We keep several self-cleaning litterboxes for them (if you have cats those things are a godsend), so they should be okay. But just to be sure, we're having our folks come spend the week in the house to keep an eye on them and keep them company.
