Thanks for your replies and opinions! You're probably right... Maybe this woman's opinion comes from the fact that in her job, she's usually seeing kitties with issues, and not those who live a happy life.

What really confused me is that she often seems to advice to seperate kitties and find another home for them when they don't get along. A couple of weeks ago, I read a book by another cat therapist, and she said that this was the last thing she would try, and that in most cases, this can be avoided. So there seem to be different opinions on this matter, even among kitty therapists.
