I do not really feel comfortable but we do leave boys when we have weekend gigs that run from Friday after work till Sunday night. I built up to it slowly, and now that it looks like boys are handling it OK I do it when we don't have our regular pet sitter available to check on them. I leave plenty of food and back up food/water, and set up several extra litter boxes. We also secure the house extra carefully (lock out most rooms, so no trapping opportunities etc).
I hate doing it because from experience I know how much better boys fare afterwards when we have had their 'nanny-uncle' stop by to play with them in addition to just making sure they are fed. Luckily our sitter is mostly available but I'd love to have a back up as good as he is. I don't think I would have the heart to do it if I had a single kitty - not at least with boys like mine because they are such wimps.
