I am VERY impressed with your vet!!!!
If Mali were my cat, I'd start her on a low maintenance dose of buprenex. I"m not sure what form your vet gave you.....injectible or compounded in a flavored liquid to squirt in her cheek pouch or the injectible form you can squirt in her cheek pouch (which tastes icky). If you are having it compounded into a flavored liquid, be sure that it has NO sweetener including maltodextrin. It is a myth that diabetics can have maltodextrin without it affecting BG. Check with your vet on what she considers to be a maintenance dose or she might have already told you. Buprenex has a pretty wide dosing threshold so I'd aim for the lower end and increase if necessary but again.....your vet can guide you on the maintenance dose. One thing I disagree on is the BG. I have seen cats go up into red and black numbers ...take a look at
Checker's SS. He has a disc problem in his back; he was throwing alot of red and black and we suggested to Barb that she start him daily on bupe. He was doing so much better but he's been in pain the last day or two and his numbers have gone back up again. Do you give her fluids? I would talk to the vet about occasional fluids if she thinks she might have a mild, chronic case of pancreatitis.
I also agree that the antibiotic is definitely appropriate if she has cholangiohepatitis. Gracie has been on a very long course of clavamox for a bile duct infection. I know Mali is also on ursodiol. Again....if you are having it compounded like I do Gracie's, double check and make sure it has no sweetener or maltodextrin. For some reason, I was thinking she gets a pill? Metronidazole (Reglan) might also be a possibility (is she already on it?) but it made Gracie sicker than a dog. She's had no issues with the clavamox. So talk to the vet also about clavamox....some cats tolerate it....some get really sick. ECID.
How are you giving the methylB12? Are you giving it by injection or a capsule? Most capsules have sugar or another additive that will raise the BG so you want something like
Zobaline. If you are giving injections, I would check with the vet because often the injections are cyanocobalamin and you really want methylcobalamin.
I hope that helps. She's a pretty sharp vet you have there. Now between her and us...maybe we can get this girl in better numbers.
