While I'm not a professional catsitter, I do look after other people cats - that is the humans are people I've known for a number of years. I refuse money or compensation of any kind. I do it because I want to and because I get to spend quality time with other kitties I love. One couple is my catsitter so we swap back and forth. It works out well. The other person is my neighbour (not the one who helps me with Max) whom I really don't care for much and she's really cheap anyway. I don't ask for any money because I love her cats and care for them while she is away.
