If Polar Bears Exist, Why Aren't There Polar Cats?

There is no cat built for the high Arctic. No felid hunting seals through breathing holes in the sea ice, no cat swimming between ice floes with blubber under its fur — while cats have conquered deserts, mountains, jungles, and swamps everywhere else on Earth. So why did the most successful predator family in evolutionary history stop at the edge of the polar ice, and hand the entire niche to bears? This video breaks down why no cat species ever adapted to life on the Arctic sea ice — from the ambush-hunting strategy that fails on open, treeless tundra, to the fat-storage biology that let polar bears survive unpredictable Arctic food supply, to the genuinely surprising history of the cave lion, an Ice Age big cat that may have been closer to a true polar predator than anything alive today, before climate collapse and early human hunters cut its chances short.
