Yesterday we lost our horse field tortoise in the garden. We've looked all around the garden but still no luck. There are no obvious places for her to escape into our neighbours' houses. We live in London and it can get quite cold at night. We think she has buried herself and don't know how to find her. We've left food outside and today we looked for them but they were gone. Weather they were eaten by her or birds we don't know. Do any of you have any ideas of how to find her??
