From the little we were told about Bolt, it was our understanding that he was always free to go inside/outside as he pleased (you probably just didn't read the fine print

) The reason we didn't keep him was that my wife insisted on making him an indoor cat and I said no way (we already have two)
When the two (old) cats we have are gone, we will never have another indoor (only) cat again. We used to have outdoor (mostly) cats... they could sleep inside when they wanted, or go out and hunt. Then suddenly my wife became convinced that as soon as one stepped outside at night an owl was gonna swoop down and grab it. Then that turned into they can't go outside ever... which I think is bullshit.
I'll tell you what I tell her... let those cats out! If something happens, I'll get you another cat"
