Damn!  I was really hoping it wouldn't be a rat, for obvious reasons, let alone a very large pregnant one .
 
I'll have a better look for rat runs, but we didn't see anything yesterday. We have a couple of live-capture rat traps, so we'll get them set just in case.
 
Any thoughts as to what's the best bait to use?

Dont know about bait - try some grain - but wear gloves when handling the traps so you dont put a human smell onto them. 
Cover the traps with something so they look less suspicious to the furries.
It may take a while to catch anything as they are very suspicious of anything 'new to them'   - except of course the bucket of feed you forget to put away last thing at night 

Good luck

Yup rats!

I put a bit of ewe feed in the cage traps and put them against the wall and under a pallet - have caught 4 so far.

If you do catch one in a live trap, be very careful when you come to handle the trap with the rat inside.  It'll have your hand if it comes within range.  So use sticks through the handles to lift the trap, and keep your hands well away.
