Schrodinger's Cat is a paradox not because he expects you to believe that a cat can be in a state of being both alive and dead (or neither) but rather that the laws of Quantum mechanics (which he devised!) seem to be unable to transcend some boundary between the microscopic and the macroscopic scale. Why doesn't the superposition state of the decaying atom carry over to the billions of wave states that combine to form the cat? One answer is a concept known as decoherance. It basically employs the notion that wave functions have a phase just as an electromagnetic wave such as light has phase. Only light waves of similar phase can display interference, evidence of a superposition state. Due to the multitude of wavestates in the cat, they statistically cannot be in phase to the extent as to be able to merge wave functions in the manner of superposition. Thus "spooky" Quantum effects observed on the atomic scale cannot carry over to the multiphase macroscopic systems of our scale.
