By the way, how is it going with Rudie?? Still accepting Whiskas? Your decription fits perfectly to Fister, he is rather choosy as well!
To begin with, he was fond of most canned food available, but he soon changed. He seems to get fed up with a particular kind of food now and again, even though I change regularly, but lately he has been eating more and more dry food (at the moment the healthy & expensive stuff, because of his bladder problems) and that's just fine, as long as he drinks! There's one particular kind of canned food he really likes, that one you can get in IRMA next time you're in Denmark. They come in 5-6 different variations (small round cans).
The small square cans that you can get most places, are supposed to be really Yummy, but those, he won't touch!

Well, I hope Rudie has changed and is eating more different things now. He certainly looks healthy!
