Kind of late to switch vets mid-process. I'm sure the new one would want to do all tests and stuff over again. I was originally planning to use them for everything from now on and bring Kili in just for a check up to get her established there as well but I don't know any more. Right now the main thing is to get Truman cured but financially it's really tough.
On a good note I got 8 grams of oatmeal into Truman just now. He wasn't eating too good this morning. His weight wasn't critically low but still on the very low side. Last time I offered oatmeal to Truman he rejected it but I decided to try again. When I offer it to him on a spoon he doesn't eat it (unlike Kili who just goes crazy for this stuff). But when I use my finger to shove it from the spoon and into his beak he swallows it right down and looks happy. He had maybe 5 to 10 mouth fulls but then wouldn't take any more so eventually I gave up. I didn't realize that such a tiny amount brought his weight up from a pretty low 312g to 320g which is a fairly normal weight for him. I also let him eat an almond and an entire walnut earlier. I understand this isn't the best stuff for him to be eating right now but considering how much weight he lost in recent days I think it's good to get him some calories. Then when he feels better he can eat his pellets on his own.
