Cougar v Muskox

I have given the edge to the Cougar on Carnivora even though I had also thought of giving it to the Muskox. This is my third opinion change but I am going with the Muskox, it is like four times larger with both at maximum sizes and about five times larger at minimum sizes. Its horns are not helping much though due to their curvature but its fur is quite helpful although it does not cover it whole body but most of it. I am now favouring the Muskox again.

I would not say it would gore the cougar that easily, Muskox mostly have curved horns so they can't really gore a Cougar that easily. I would still say this is quite close though since even grey wolves have killed bison so a cougar should be well able of killing a Muskox as well. 50/50 but I am leaning towards the Muskox
