Ben is an 11-year-old Applehead Siamese, 15 pounds, very fit. Good self-regulator on food. Previously, we were leaving out Science Diet Hairball Control Mature (dry), twice a day giving half a small can of Science Diet Savory Chicken (wet), and allowing him a handful of Butler Schein American Tartar Control Treats once or twice a day.
Very active all his life, then just a few days ago, I notice he was drinking much more water, urinating in much larger amounts, and seemed stiffer in his movements. Took him to vet, she extracted urine - it was very pale and had glucose in it sufficient so that she said "definitely, it's diabetes". Hadn't lost any weight, though, so we are pretty sure we caught it relatively early. Also did some blood tests - we'll get the results today.
We've given him 1 unit of ProZinc insulin twice a day since Wednesday evening. Put away all of the "old food", including the treats. Did some reading and bought new wet food: Wellness Chicken Formula, Wellness Turkey Formula, and Merrick Turducken. Vet provided several cans of Purina DM wet and a bag of Purina DM dry. We haven't given them the Purina wet as yet (using the Wellness & Merrick instead), but have put out the Purina DM dry. Both cats (the other is Bert, a 10.5-year-old Applehead) seem fine with the changes so far.
Ben was very quiet yesterday, wanting to sleep all of the time. He did get me up this morning for breakfast, however, and we'll give him another one unit of insulin in a few minutes. His water consumption appears back to normal & and the peeballs have decreased markedly in size & number. We'll have another blood test done today, just to see what's happening. We are very nervous about doing the blood testing ourselves, but we'd like to learn.
