Help arrived the next morning when I climbed up the tree to her. She was happy to see me and desperate to get down from that tree. Since I was not approaching her fast enough, she came down a bit to me and looked for a way to get on my lap. She was not going to miss this opportunity to go down. I spread the cat bag on my lap and then lifted her up off the limb and placed her gently on my lap. She was content as I petted and reassured her, and then I pulled up the sides of the bag all around her and secured her in the bag.
Betty was happy to be back home, and she ate a big meal and began working to remove all that nasty Pine scent off her coat.
