Thanks Hazel for the suggestion. I gave him half of what he normally gets and had planned to feed him more if he wanted it and had kept it down. Today I plan to feed less than I did yesterday in hopes he is able to keep it down.
Last night he ate the rest of the food in his bowl after I posted and was able to keep it down. He is lying in the living room today, not in his bed, and seems more active even though he is tired. So I'm hoping he can keep the smaller amount down today
From what I see it definitely is not time to make a decision yet and hopefully he will rally from here Only time will tell...
