Do You Think the Laws of Physics Are Universal?
In practice, you will always observe the cat to be in a microscopic superinm ind. The bare formalism of quanta mechanics would not answer this question. Most text books don't talk about decoherence or pointer states as they are called. That's basically the reason there is a classical regime that ouget by focusing in on quantum systems that are microscopically in certain places. And those are the states we actually see because that's how decoherence works.
