She got in once (we left the gate open), but, she couldn't get back out, even with a gardener or two chasing her around! (It's a tad over 6 feet tall). I had to prop the gate back open so that she could go back out. She attempted to jump, at full throttle, and managed to smash into it a time or two before we realized she was only going to go out the way she came.
She seems to spend at least a few minutes everyday looking for any weak spots
She also has the cutest baby, who spends a good part of its time in the unlived in house across the alley, under all the pine trees and lilac bushes.
