Kirsten, I'm so sorry about your health problems, I hope you won't have to go to hospital.

I can see it's a problem having Luna and Lily taken care of if anything should happen and I was thinking... perhaps you could start a Meet-up group in your area for catsitting. The group we have here works very well. We meet every now and again to have dinner, either in town or at someone's house. That way we can find out who we "click" with and who have the same attitude to cats.

Here's a link to our group. The founder of it is Dagmar Fink and German, by the way.

I searched in the Hannover area, but could not find a catsitting group there.

Hope you feel better soon
