I like this thread and coulsn't agree with you more! I have one cat that I got as an adult (Well 1 yr old) and he is lovely! he did have issues when we first got him.... But more to do with contact and stuff!
he has now settled in and we have had him for just over two years, he will occassionally sit on my lap but has never been over cuddly though! Difference is he doesnt hiss when you go near him any more and even tolerates strangers ehich he never used to do!
With a bit of care and attention you can definately work through problems that you may have with older cats - and usually quicker than it takes to train a kitten
