I have a semi-indoor cat. I want to make her an outdoor one so I don't
have to worry about her escaping through any of the many exits(patio
doors, conservatory, etc). I live in a cat-friendly neighbourhood but
my cat six months old has only been out on a liesh thrice a week on
average for about ten minutes each time. She was off the liesh briefly
during that time.

I think she has enough experience of outside to not stray, and is a
really clever, neuteren, girl, but she's my first cat and I want to be
sure. How can I?
