Well, that was funny...
...I was just answering the comments on my post about the Barn Owl, when Jo walked into the room and asked if there was any mole hills today, so I told her I had noticed a small fist-sized lump next to an old mole hill and thought nothing of it.
Jo went in to get Zak dressed for the day, when I heard a little squeal, and Jo shouted out that the hill was moving!
So I took a look, and sure enough the molehill WAS moving, so I rushed and got my coat and boots on to go outside.
I picked up a spade from by the shed, and tip toeing round to the hill I braced myself.
When I was within 10 feet of the hill I took a few large steps and...
I brought the spade down on the mole hill, and dug frantically to see the mole.
Unfortunately the little wotsit had already gone, but it must have moved incredibly quickly to get away, as the hill was still moving when i was 1 step away from it.
Thinking I'd take action against this little critter, I put a smoke bomb down into the tunnel, and hopefully the coating of castor oil will put him off again for a while!
