are mice known to inhabit loft spaces or could this just be one mouse
that has become trapped in the loft for some reason? - (bearing in mind
that its a semi detatched house with a fairly high roof)!

Mice will inhabit anywhere which has a food supply. My mother recalls
lying in bed in rented accommodation listening to them thundering around
above the ceiling, and an ex-boyfriend in an unaccustomed fit of
cleanliness decided to clean his gas cooker, and found a nest of mice
snuggled up warm close to the pilot light.
