One more additional point...
When they talk about the cat being dead or alive, they are not talking about a specific cat having two simultaneous states - dead and alive. Rather what they’re saying is that in a population (distribution) of cats, a particular cat can be dead or alive (it can also be sick or well, black or white or orange and so on). Until you open your eyes (sample it) and actually see it you don’t know what state (or color) that particular cat is.
Once you’ve seen it (sampled it) that particular cat can no longer be dead or alive or black or white at that instant in time. Later on, on seeing the same cat it may be somewhat different than when you saw it the first time, because it just got run over by a car. Like the human called Bruce Jenner was a good looking man 20 years ago and when you see him today he looks like a delusional ugly woman.
Until you open your eyes and sample it, you don’t even know whether or not it’s a cat.
Nice!
