What Schrödinger’s cat REALLY means

My take is that Schrodinger was saying that quantum theory had its faults.  By definition and posits, quantum theory says that matter and energy exists in discrete states and only discrete states.  Schrodinger says, well wait a minute.  Life and death are clearly quantum states but in my thought experiment, the cat is both dead and alive until, and that is the key point, until you observe the cat and are able to determine which state it is in.  He demonstrated that while quantum theory does indeed explain a number of things it is far from explaining everything.  Additionally, I think that Schrodinger is drawing on Heisenberg's Uncertainty Principle that for example says that you can determine the position of a particle at the expense of determining the velocity of the particle and vice versa.
