Kleiber's law

Kleiber's law, named after Max Kleiber 's biological work in the early 1930s, is the observation that, for the vast majority of animals, an animal's metabolic rate scales to the 3/4 power of the animal's mass. Thus a cat, having a mass 100 times that of a mouse, will have a metabolism roughly 31 times greater than that of a mouse.

Kleiber's law, as many other biological allometric laws, appears to be a consequence of the physics and geometry of animal circulatory systems.
