The cat was first invoked as a kind-of-mocking thought experiment and a point of critique towards (the Copenhagen interpretation of) QM, IIRC.
(The answer to the thought is that yes, indeed, the cat would already be in a single state prior to observation, because the large macro system would have decohered and collapsed into a single state prior to an observer checking the status of the system.. unless I'm mixing something up.)
- Filligree 11y agoNo, that is indeed what would happen in practice, but it's theoretically possible to prevent decoherence even in a system this large. The thought experiment was about this, theoretical possibility.
