That’s Molly, our escape artist. First we installed a Diamond Back fence, bent inward at the top to prevent the cat from going up and over. Molly, being so special and smart, grappled her way out real quick. Finally, we had to resort to a mesh tennis curtain hanging from the rolled top. That did the job. But then she went over to a tree, climbed that and jumped over the fence. But most cats are not that determined!
