Ours have never been like that. Have you ever actually owned one?
I have, admittedly when I was quite young, but never really liked it then either. My nans got one, I go round every other weekend and I probably see it once whilst its being fed. It hates being picked up or touched by pretty much anyone, only my aunty and grandad are allowed to touch the thing. Fair enough, I probably wouldn't like that one much either (although maybe it can sense that YOU don't like IT). That's just one cat though. Haven't you ever come across a neurotic dog? I certainly have, but I wouldn't write off the whole species on that basis.
To be fair I don't think I've ever met a dog that I didn't like, barring those that are under knee height of course, they shouldn't be counted as dogs anyway. I've just never met a cat that seemed worth while having around because they have their own things they want to do, where as a dog wants to do whatever you're doing, I guess I'm just more a dog kind of person.
