At last I have discovered something that my sociable barn cat, Freddie, does not want to make friends with. He finds an excavator alarming.
All day long, as the excavator roared at the edge of the barn, you would never have known I had one barn cat, much less two.
However at 4 PM when the excavator was silenced and the operator left, both Freddie and Flossie crept down the ladder from the hayloft. They sat on the back dutch door of the barn and watched me re-erect the paddock fence and re-wire the electric charge.
It’s much more relaxing when it’s just us chickens.
