I don't know how I missed this thread!
As far as people food - CHEESE! Pinot is crazy for cheese! She'll climb on the counter and try to get to it as you're slicing it - lick the cutting board and knife...she's never had it as far as I know, so I don't know where this comes from.
Cat food - she knows when her feeding time is and won't let you forget it! If we're not home on time, or the cat sitter is late, she'll open the cabinet and try to get to it. We've put the food in a plastic bin now, so she can't get it, but she'll still try!
In other words, no, she doesn't beg. She DEMANDS!
