Thank you all for the great information!
I still didn't get the exact numbers from the vet, but he said that the blood results ruled out all of the problesm that bloodwork shows, and she he is trying to treat it as IBS, with prednisone and at first had given me Cerenia for vomiting, but now has given me Reglan. (He is 14 yers, and I rescued him for BRAT as an owner surrender at the shelter.)(He has never been a pickey eater until the last month.)
From reading the above post, I think I was messing up his taste for foods, possibly, because he would stop eating something, as the first time I gave it to him straight out of the can, and since I thought he liked it, would put Missing Link in it the second time, and then he would reject it. ( I have been giving him Missing Link since January, and it never bothered him before.)
So now I have been trying the food cutlets in the sealed packets starting yesterday, and today is the firsd day he hasn't thrown up yet, an today is the 3rd day on the Reglan, so maybe a combo of the 2?
I have also figured out that he doesn't like drinking water from the steel bowls I have, as he will go to my boyfriends and drink alot from the plastic bowl there, and not drink much here… and when I put both down, he would sniff the metal bowl and go to the plastic one to drink. Maybe that's contributing to the food as well?
Lord, who knows...
I'm just happy I didn't have to clean up vomit this morning...
