S.H.
I do remember your previous questions (including the MIAs), so I do "get" it. However, your welfare is the most important aspect right now. I appreciate your commitment to your cat.....& hope/pray he'll be able to stay with you....whatever may be in your future.
1st step: who has legal ownership of the cat, who's listed on the paperwork? Who pays for the care of the cat, both food & vet bills? That's your starting point..... Peace.
