I adopted a barn kitten when he was 2 months old. That cat would catch elk if he could!
My sister adopted a barn kitten. When she got him in the house, he detected and killed a mouse within a half hour of his arrival.
We adopted a barn cat to actually live and kill mice in our barn. Sweetest cat we ever had but not a mouse in sight.
Its nice when someone is actually good at their job.
Growing up in the country we had a number of barn cats pass through our lives. Some were friendlier than others, of course. My dad didn’t regard them as pets; they were there to keep the vermin population in check.
I remember my grandmother being a little upset one day when one of our cats dropped a dead rabbit at her feet.
