I think a conversation with the vet is in order. Is this cat eating a crazy amount of food for there to be that much, shall we say, output? Since the cat belonged to someone who appears to have been either in ill health or elderly, perhaps the cat has food insecurity and now at your house is loading up because it got used to not knowing when it's next meal was coming?
Just throwing ideas out there.
My sister has a bunch of cats and according to her it's a thing that they claim litter boxes. She has them on all three levels of the house as certain cats prefer certain areas.
She has mentioned a cat that she has to ration. Apparently he'd be the size of a small car if she let him eat any time.
I just have one cat so I don't have those issues. Just thinking out loud as a pet owner.
