Any news on Geoffrey yet? Am sending lots of healing your way.
Oh, in case his mouth is sore, which of course it will be, may I suggest using some Nutri-plu gel...it's a " dietetic complementary feed for cats and dogs
nutritional restoration and convalescence. " It's a gel that you put on your finger and most if not all cats will lick it right off as it smells and tastes lovely (no I haven't tried it, but Bubbles, Ali, Gizmo and Widget told me so.
I have used it over the years for poorly feeling critters and it is wonderful. Even though they aren't eating, you know that they are getting the vit and mins they need to keep going and recover. Don't leave the tube unguarded though, as they will pack it off and eat it all in one go, which I am sure wouldn't be all that good for them. It's available from most of the on-line vet places and when I ordered it, I got free delivery and it came the very next day.
It sure helped when Widget had all those problems! Come on now tell us how your boy is??
Love ya
