My preferred interpretation:

There is a density function across all possible realities (Hilbert space).

Schrodinger's cat has equal density of being alive and dead.

The person who opens the box can be happy or sad.

The density of cat being alive is entangled with the observer being happy. And the opposite for the death.

The original cat distribution did not "collapse" or "resolve" per se. The cat is still equal parts alive and dead. But it did become non-uniformly entangled with the distributions of rest of the universe.

Perhaps this is the many worlds interpretation.
