When I was a kid we used to learn useful stuff in school, one item of which is never get between a she-animal and her offspring.
Here’s some stuff that happens in the Canadian wilderness: A defence of angry bears. (Actually, I think the bear in this case is a he-bear, but a she-bear would behave exactly the same.)
In this next one, the cat wins, and you will see why: This is a defence of angry cats.
But, if you watch it through, it is not a defence for bear behinds.
