I don't think I could ever board my kitties. I think they would just be too scared, being in a strange place without me. I have a petsitter from the company I work for come over and take care of the kitties. They really seem to like her and she does a great job. Plus having a sitter is nice because they can alternate the lights, water plants, pick up mail and other little things so that it doesn't look like whoever lives there is on vacation.
