Whose poo?

Just recently started to find these distinctive poos on our lawn and path.   Approx 1.5 cm diameter x 10 cm long.

Have seen a rat, but they are too small for this poo.
Hedgehog, perchance?
Could it be a foxes poo?   
Certainly a faux pas, being immediately outside our side door, ripe for being stood on.  Ugh!
Anyone know for sure?
