I went with my cat a couple of times to Chatterie du Persan, route de Thonon 222, 1246 Corsier GE. It seems quite ok, although I don´t have much comparison from other places. My cat prefers staying at home when I go away. But this Chatterie is not too far and reasonably priced.

My recommendation: Have a friend feed them indoors-only, but if you can't do that, then a cattery would be better. I'd not want my cats to wonder, where I disappeared to and go look for me further outside the garden! :)

@Josh - a quandary indeed. When I can I get someone to cat sit but the cats stay inside. I'm looking into cattery options so that I have a back up plan if no friend is free to do the honours. I'm going to look at a cattery in Lancy at the weekend. It seems that all the cats are in a big space/garden together. The question is will this create a big love fest or a blood bath? I'll report back! The website of the place is: http://www.of-liberty.com/index.htm

@Siany I take my dog there. He loves it. Every time we go he cannot get out of the car fast enough!
