I’m concerned if I increase his numbers, they will drop below 68– he seems to be all over the place. I’ve been changing his food which may account for some of the irregularity. At any rate I nudged him above 2.25 this morning because of the 604. Yes, 21 yrs old —good days, bad days.Doesn’t look like you are following TR any more. He’s been on this dose way too long. He really needs an increase. Is he 21? You are definitely doing something right.
