Flat as a pancake

We were tidying up tonight and Al thought there was a bit of a lump under the rug, he lifted it up and there was this poor little mouse, totally squashed flat, it reminded me of the flowers I used to press as a child in a little wooden flower press.

No idea how long it has been there or quite how it managed to get there. Did it come into the house of its own accord or was brought in by one of the cats? Did it run under the rug to escape the cats or were they playing with it and flicked it under the rug?

Poor little mousy - its a dangerous house for little beasties!
