The cat is a pickup truck

Schrodinger proposed a scenario with a cat in a sealed box, wherein the cat's life or death was dependent on the state of a subatomic particle. According to Schrödinger, the Copenhagen interpretation implies that the cat remains both alive and dead until the box is opened. So you see, it's not about what you can or cannot fit into the box. This is because the box contains a dead cat. Which would have been much better of let out of the bag in the first place. Think outside the box.

We play the ancient game of snakes and foxes. And I am hunting the masked moose.
