I just saw that. Next time you are in Canada, ask if anyone has seen moose horns attached to skeletons, locked in battle to the death. I've seen those when I was in Alaska.
And bovine bulls? I had to take one to slaughter because the crazy angus broke his hip when the 3 of them were slugging it out. I shared a pasture with 3 bulls for about a year. Then there were 2.
Your Disney view of the world doesn't work.
Not for mammals, not for birds (watch chickens, sometime, for a year or two), not fish, certainly not for reptiles.

Again, those are not ‘my’ “views,” but Grossman’s.
