Very true...even grizzly bears are afraid of them.
Ahh, No. Your thinking of a Badger. Mink can hold their own against simular sized rodents, but they don't go looking for trouble in general.
I heard on a trip to Yellowstone that bears were afraid of them...maybe I’m misremembering. As for badgers, I hadn’t heard that they encounter grizzlies, but wolverines will take on grizzlies and cougars to defend their carcasses.
