The 'cat state' is an unobserved state (if such there be). Once you peek in on the cat, the superposition of states collapses to a single state (so it is said)...unless you hold that each state in a superposition is just as 'real' as any other and that, at each observation, a system splits into separate, equally 'real' systems that continue to develop in complete separation from each other. This bewildering, branching view of 'reality' is called 'the many-worlds interpretation of quantum mechanics' and is the preferred view of 'reality' of many quantum physicists.

Yes but can an entire cat ever be in the cat state? I'm reminded of the difference between ordinary, incoherent light, and laser light. There's too much cat, made up of atoms all on different pages, so to speak, for the aggregate (cat) to be in a cat state.

Zeno would have loved this stuff.

By the way, does the cat's observation count for anything?

In my reality an empty box placed in a room with a live cat will soon have a live cat in it.

I prefer to think of it as more like the evil Mr. Spock on an alternate USS Enterprise in an alternate universe.
There is a universe somewhere where the mainstream media is honest, Saddam was the benevolent ruler of a peaceful country, Bush is an evil moron, and the Democrats aren't all stupid liars. And you thought that the dead/undead cat was weird? Just think of how weird this place would feel to us!

But only in this reality.
