Was just about to say the same thing! They are extinct around here..I'll tell you exactly what happened to them.. those stupid otters some idget decided to stock in Tennessee years ago ate them allWow, haven't seen a muskrat in years and years.
They used to be plentiful in middle Tennesee.
I have heard several theories on what happened to the population, I suspect is is a combination of things.
Used to love trapping them when I was in school, it paid for my school clothes.
