Hello all, I am glad to have found this site while browsing for information about my Tommy's lack of reaction to ProZinc. He was just diagnosed Oct-2017 after sudden weight loss - used to be about a 14lb boy, but was down to 11 over a span of less than 3 months. When he was first diagnosed, we visited the vet five weeks in a row, starting with 1 unit twice a day and quickly worked up to 4 units twice a day. I took away the dry food immediately after diagnosis and fed only friskies pate (previously he received 1/2 can of friskies ~2.25oz in the morning and evening and always had dry food available to snack on). I got an AlphaTrak2 from adw diabetes, but our vet still wanted to do fructosamine tests every few weeks-these have always been in the 400s as well. During these few months, we tested at home every few days just before the PM meal and shot, and we graduated over to Fancy Feast since the classics usually have lower carb %s. Other than the weight slowing coming back (vet and I agree he's good at 12lbs), none of the other symptoms have gone away. He drinks alot. He pees alot. He is hangry all the time. His front legs twitch when i pet him. His hind legs are looking weaker all the time. I have communicated with her intermittently with the alpha trak log results as i see her pretty often (i have another kitty and two chihuahuas-basically 4 cats). Tommy had pancreatitus about 3 weeks ago after another fructosamine test where we upped to 5units twice a day - always in the 400s. He received subcutaneous fluids two days in a row, and a 5-day treatment of cerenia and buprenex. His vet told me to feed him anything he wanted just to get him to eat since he was down to 10lbs and had been vomiting; and since his sugar was still so high to go ahead and give him now 5units of insulin twice daily - maybe adjust-down the dose a little if he wouldn't eat. After the first two days of getting the fluids he seemed to be doing better and we continued the cerenia and buprenex until the regimen was finished. This last week he was sick again (15 days later). I rushed him back to the vet with the same symptoms of pancreatitus not eating, not feeling good (no vomiting this second time). Vet says i overfed him, his belly is too tight and full, now he should only have 6oz per day. He received fluids one-time, a shot of cerenia at the vet, and came home with 2 cerenia to be given 1/2 pill once every 24 hours. He just finished those last night. We limited him to the 6oz per day for those 2-3 days and he was not at all happy about it! I am ashamed to say he has had about 9oz today and his sugar was actually in the 500s at the PM after 2 hours of fasting. I feel as though i keep getting different messages from the vet - make sure he always has food available, oh you're overfeeding him, let's increase his insulin. In her defense, we did remain at 2.5 units for maybe 3 weeks to see if he would respond, but that was the only time we used 1/2 units until this pancreatitus up to 5.5 (which was only 3 days after the fructosamine). She is always referencing him being stressed after we see BG results. I am unsure about that, he is the king of the castle here and he has a wonderful personality! I asked if she thought it was time to try another type of insulin but no we should just keep increasing. ugh! I need the link to your spreadsheet seen in other posts. I purchased some ketone sticks today from walmart (hoping to try the saran wrap in the litter box since we have a hooded large box and i don't think he will go for me hovering). I had no idea we should be testing before every meal, we have no problem doing this. Our vet was saying every couple of days when feasible. I am hoping that we have just missed his optimal dose with fast, whole increases - similar to what I've read in other posts. Please advise, you all seem so knowledgeable about this. I am so sad I've waited this long to try to educate myself more about feline diabetes and relied on the vet too much.
