I dont agree that they are not much trouble - I used to spend hours hunting mine down in the garden - then we fenced a large area off, which is when she started to climb and tip herself upside down. I used to dash home from work with the fear of finding her upside down and she had died. Many a time she was on her back, legs splaying everywhere, fortunately we always caught her in time. And....I think she was spoilt, as she wouldnt eat her food off the floor, I had to hand feed her. She was so old she could have been blind, we were never sure.
