I find that my retics digest food at the same rate nearly regardless of size whether a jumbo rat or 4xl guinea pig. Give him the biggest rat you have and see if it lasts any longer than the previous meal. I agree, 5lb rabbit is probably overkill but if you offered it he’d probably give it a try. I’d hold off though.
And yeah, don’t you just love cleaning piss every single day?! Just fully cleaned out Gerald’s cage earlier and he peed all over it within a few hours...
