I don’t think this was about the intellect either, just about empathy. Sure, the free rat could learn to open it quicker, but the point is that it did. It didn’t eventually figure “eh, nothing in it for me”, it repeatedly went and freed the other to the point of routine.
They’re known to be the only animal on the planet more intelligent than dolphins.
IIRC only two of them survived though, while the dolphins all left in time.
Don’t think there has ever been much dispute of a rat’s intellect
