Kirsten you are an impatient girl (which I understand very well). In your last post you said you wouldn't expect them to be friends in the first 5 minutes. Tigris and Filou have not been friends for more than one week although both were kittens of 13 resp. 15 weeks old

I was in panic then (stupid me) - but then there came the day when both were lying in the same basket.

So try to relax.... (I know to say that is easy) -what I hear from Luna and Lily sounds absolutely normal

And have fun!
