LOL JJ....I hear you. We have been running out of volunteers for our little psycho....I mean kitty as well.
Fortunately, we have an unsuspecting fearless new neighbour who kitty sat last time we went away. It will be interesting to see if she will do it twice, or if she will be busy washing her hair that week.
But pet sitter or not....I do feel sad for them when I leave them. I spend too much time wondering if they understand.
