Thanks Ria P for your thoughts on the house/nest , and your suggestion of the guinea pig house that you currently use. I've had a look and I can see what you mean about feeling secure.
The bendy wooden bridge is under the large shelf that came with the cage(she has x2 shelves in her cage) and is full up with tons of substrate. Its all very dark and we can not see her. The surrounding area has substrate around her nest and is up the sides of the cage where she sleeps (she is well hidden). Trying a different nest might work for her and I appreciate the advice, thank you. Will have a look on amazon / pets at home. Might be the answer to the meals on wheels thing
