Is this normal? dying or just old?

[Pandora]

I do take mochi out quite often, so I know hes a bit desensitized. I just dont know to what point it fear passing out or just that comfortable. Then theres the question, hes almost 2, so it could be arthritis or some underlying pain. Is he aging? Hopefully not dying yet. I may try a drop of cbd

Older rats when comfortable often do fall asleep when out for play time. Rats generally don't pass out from fear, they cower. I'm not seeing lethargic movements or obvious signs of pain from the videos so I'd say he's probably just an old lad getting some rest with his companion !
