Unexpected Help

I am still continuing with my dig although I have been hindered by bad weather and other demands on my time. Recently, after a prolonged period of rain, I looked in the pit and saw that I'd had help! A hedgehog had wandered in and could not get out. Over a period of days it had scratched away at the sides in an attempt to escape. Luckily I managed to lift it out in time and initially it looked exhausted but when I started up the lawn mower to cut adjacent grass it uncurled and fled. I now leave a hedgehog escape ramp in the pit when I am rained off.
