I lost one of my tortoises. They were both in their outdoor pen, when I went to bring them in at dusk (I'm an over-protective parent!) I could only find one. Tried to play detective, but could see where he could have got out. Stood in disbelief, wondering if I should go search the neighbour's garden, when I heard tiny munching noises. He was in the lettuce patch, and was so full of veggies he couldn't even be bothered to try to run away!
