I saw a mouse, where? Not on the stair!

Not a good day as I started it at the hospital out of hours surgery!  Nothing serious but I needed a prescription as my eye had flared up, arthritis in the eye, painful but I knew what it was.  So having been awake most of the night I dozed a lot all day and only took a couple of shots of this little mouse.  Not seen one here before and if my cat sees it I might not see it again!
Please accept my apologies if I don't get round to commenting but my eyes won't let me spend too much time looking at a screen, so annoying!
