Well, the vet called and his numbers have elevated a teeny tiny bit. Nothing to worry about though. WHEW!
His thyroid and glucose came back good too.
She said if his numbers go at the rate they are going, he'll be with me for a long time to come. WOO HOO!!
She told me to just keep an eye on him and if he does not eat for two days solid then bring him in and they will have to figure out what is up with him.
That is what happened back in 06 and we never did pinpoint what his problem was.
So it looks like my Tazmo is stuck with me for many years to come! I just wish it wasn't so expensive to find that out, lol.

Thank you all for your support.
