As I understand it if we go along with the Schrodinger's Cat thought experiment we can say that the cat is in a state of superposition. And that the cat is both alive and dead. That is until someone looks in the box and observes inside. At that point the wave function breaks down and we observe the cat as either alive or dead. I have then heard if there is no one else in the room to observe other than the single initial observer. Then to someone on the outside of the room with the initial observer and the thought experiment then the entire room is considered to be in a state of superposition until someone looks in to observe.

Anyway my question is if there is nobody but the initial observer and the unobserved thought experiment in a completely isolated and sealed room (No one can observe in upon the room) and the initial observer looks in the box and observes the cat as alive or dead then reseals the box and by some arbitrary method entirely forgets what they have observed, is the cat in the box put back into a state of superposition where it is both alive and dead? Or does it remain in the state that the initial observer observed it in before forgetting?

Thanks.
