In a cat's meow, entanglement is the phenomenon where two particles become connected, so that what happens to one affects the other, even if they're on opposite sides of the universe.
A cat in one box is entangled with a cat in another box. What happens to one cat instantly affects the state of the other cat, even if it's a million miles apart.
