I know that cheetahs have large lungs, a large heart, and a large liver. I can understand why they have large lungs and a large heart. It is so they can get enough oxygen to their muscles during a sprint. But why do they have a large liver? Do their red blood cells die really fast or something? And if you are going to tell me to speak to a professional about my obsession with cheetahs(and the professional might tell me to take care of some cheetah cubs to eventually release them back into the wild and see what that is like(this would probably strengthen my obsession with cheetahs)) let me tell you this. Cheetahs are 1 of my favorite cats.
