It depends on what interpretation of QM you subscribe to. Copenhagen would say asking which state it exists in is nonsensical. It is existing in many states simultaneously. Observation causes a deterministic collapse of the wave-function. In other words, reality is in the observation not the cat.

Many worlds theory would also have the cat dead and alive simultaneously. The key difference is that the wave function doesnt collapse. Putting the cat in a box created multiple universes within the multiverse. Ones with dead cats and ones with live cats. When you observe you see which cat world you live in.

There are quite a few other interpretations of the nature of quantum mechanics but I will spare you.

The Copenhagen interpretation is the only interpretation which is accepted in the physics community.
