Thanks for your comments! :)
I'm glad that you're all sure that our kitties love us! :D The stories you have told are the best proof! :) Luna, however, always wants to be with me. She's always near me, we're very close.
And I know that Lily is very obsessed with Luna. I think she's the center of her world (which sometimes seems to be somewhat stressful for Luna, though)
As for some cats not getting along with others... Well, I'm sure there are cases like that (for example my mother's kitty Dino who choose the life of an outdoor cat the day Peggy moved in). According to the book of the other behavior counsellor that I read (Petra Twadokus, I don't think her books have been translated into English yet), it is in most cases possible to work with them and reach a state of co-existence. I found that very interesing. (That woman btw is running a school for cat behavior counsellors, and I think if I'd ever win the lottery, I will take some courses!)
Re. cats having access to the outdoors... Many people here in Germany do also believe that a cat needs to go out to be happy, but I, for my part, have made the decision that it's too dangerous. Some people would call me seflish because of that, but I hope I'm doing the best I can to give my girls the best life possible!
