My cat, Rocky is an 8 year old, wonderful Tabby. About 5 months ago I noticed he was drinking a lot more than usual and took him the vet. BG read 450 He had an episode with a urethra blockage when he was 2 and came very close to dying. My vet had suggested feeding Prescription Diet Urinary Care from then on. 6 years later here I am. I mentioned the high carb factor a few times and the doc. did not feel as it would have a significant impact on his BG, which didn't make sense to me. He was started on oral Glipizide which was not helpful, since then he has gone on up to 3 cc Relion Novolin 2 x daily but changed to a mix of Prescription Diet Urinary Care & Purina Pro Plan DM, both dry formulas. His BG readings last Sunday were 450-519. (I started to do home testing because Rocky was completely freaked out when at the vet) I called the vet and he said to increase to 4cc 2 x daily. I was so upset with this issue that thankfully I got on line and starting reading info on wet vs dry foods by Lisa Pierson and the effect on BG which makes total sense. I changed him over on Monday and lowered his insulin to 2 cc 2 x daily with each feeding, 1 can of classic Fancy Feast at each with added water to each serving. He is definitely drinking less and seems better. I don't know if it's too soon to test again, but I'm planning to do it tomorrow and so hope to see better numbers. I'm very nervous about making these changes on my own and would really appreciate some guidance. I am thinking I may need to change vets.
