Hmmm...I've never paid for a cat sitter before, of course when I was a youngin our cats just kind of wandered in and out, stayed in the barn...heck I don't even remember buying cat food. Mice tartare, yum!
I don't know, I suppose I'd take into account my expenses (gas, would I have to buy cat food?) tack on a bit more to make it worth your time and go with that, $5-10 per visit seems reasonable to me. Honestly though if its a friend and its not to much of imposition I'd just offer to do it for free.
