As Pixel got bigger, she was able to stretch across from the trees over to the top of the fence, walk its length, and subsequently over the house and to the neighbours via the carport etc...etc. To stop this I've installed a 20cm strip of polycarb along the face at the top of the fence line. Completely stopped her. Nowhere to stand. Kitty not keen to jump 3m directly to the ground (over the fence) simply to get out of her favorite playground. Mission accomplished.
