Schrodinger's Cat Part 3

So there you are, with a closed box and a cat inside, and you flip the quantum switch at time zero. There is no way to know, even in principle, if the cat is alive or dead unless you open it (or the box moves). Basically, Quantum Theory has no way to predict the time T that the cat will die. You might say that this proves Quantum Theory is incomplete. But I ask why? Why does reality have to be deterministic? Why does one cause have to only lead to one effect?

I submit that there is no reason, either in logic per se or in experiments, to reject the idea that at some time T, the cat might be alive or it might be dead and that there is no way to know except probabilistically. And that is all Quantum Theory provides.
