I have a wood turtle who use to climb up the screen door to the patio by wedging herself between the screen and the glass door. Apparently she had some cat DNA in her.
I had a snapping turtle for almost 20 years. He was always a problem; jumping out of his water bowl. We used a wash basin for his pond at first. He never succeeded escaping an aquarium but my mother thought he'd be happier if he had somewhere to sit out of the water. She was probably right, but when she made a pond for him in her back yard he disappeared and we never saw him again.
