I think if u bring up a kitten indoors, then there shouldn't be any problems with the cat wanting to go out all the time...

But i agree that breeds such as persians tend to be more domesticated.. Actually My cat Issy, was totally terrified of stepping out of the house, when we first introduced her to the concept of outdoors, as she has been brought up as an indoor cat...

And i believe that cats r happy staying indoors as long as u give them some "private space" of their own... Only negative side that i can think of by putting them indoors is that they tend to scratch your couches and sofas.. so watch out if u've got an expensive leather couch!!!
