I am so, so sorry for your loss. My heart aches for you and I'm in tears right now feeling your pain. Gently journey sweet Max, you are loved.
I'll ask my feline-only group if they can recommend anyone south of them. My vet's SO is also a vet and works somewhere in NYC. Not sure exactly where but as soon as they come back from vacation, I'll get on her about referrals.
Hang in there and know that you are not alone, we're here for you.
