Ask me about the moon landing or the temperature at which jet fuel burns. You may be surprised at what you learn.
The cat decides you need to sleep at the same times that the protagonist of Persona 4 decides he needs to sleep of his own volition. There are even a couple times when Morgana isn't around, but the main character decides he needs to sleep anyway, just as though Morgana was there.
If the cat was patched, it'd just be replacing "You must be tired" with "I'm tired".
I think this is more a reflection of the cat narrating everything for you when some things dont make sense. Would have been better if the MC internal monologued some stuff with thought bubbles.
