Many years ago I hunted rats with a ferrets and a pack of terriers for sport and for work, hence my name, My best terrier marked a hole so i put my ferret into the hole and she backed straight out, I had never seen her do that before, I encouraged her to go back in and again she backed out, So I got my spade and started digging, suddenly a rat appeared at the hole and raced back in, I turned over another spade full of soil to see this rat run right at me, she attacked my boot and bit it savagely, she then ran back and stood over her nest of pink babies. She got my respect that instant, I covered her, and her babies and never hunted rats for sport again.
She taught me a lot that day.
