The largest lion I think ever recorded was about 690 pounds. The largest tiger ever recorded weighed in at about 857 pounds.I don't know, that tiger fainting due to exhaustion looked awfully real.
Tigers are solitary, so they hunt individually. They are constantly killing shit.
The female lions do most of the killing. The males protect the pride, but they aren't killing other animals like tigers.
The tiger in that video was two years younger for a reason. And he still was about that action, even when exhausted.
