Who would win a fight a Siberian tiger or moose?
Tigers don't like animals that are able to fight against them.
They would rather have one that runs away from it, and be in a
location where they can leap on the back of the animal and deliver
a killing bite to the neck. In an all-out fight though, a moose as
a better chance of winning because of it's weapons (large antlers
[bulls only during rutting period] and/or sharp hooves) that it is
able to use against that tiger. Though tigers are quite fierce
themselves, and are better equipped to defend and kill their prey.
So it is likely, though after sustaining some serious lacerations,
the Siberian Tiger may win.
