My 15 yr old cat Wilson was diagnosed with diabetes 6 months ago and he is getting worse. I was advised to feed him Science Diet MD so changed his diet around 3 months ago. Since then his BG levels increased. As I expected they would. This went against everything I have read as most advise to stay away from dry food. He was very skinny so the diet change was also suggested for him to gain weight. He started at 3.8kg and is now 4.6kg so that part has worked. Now I am worried he is suffering from neuropathy as his walking is getting worse by the day. He is on lantus and currently on 3 units in the morning and 2 at night. I use a all star pro insulin pen. He has other underlining issues such as glaucoma in one eye which was damaged from a kitten and has been blind in that eye all his life. We are discussing having it removed but worried he's not stable enough due to his diabetes. He is on Cospot for his eye, 3 drops daily. Also a small dose od Meloxicam every morning in case he is in pain with his eye. He also has high blood pressure and is on Norvasc for that. Now they tell me his potassium is getting low and we have started Hypokal at 1 tab twicw daily. I am worried that the medications are all becoming too much. I test his BG and urine at home. His BG averages are around 25 - 30 mmol/L. Urine shows no ketones but high glucose. I regularly see my vet and have also seen an animal diabetes specialist but still don't feel like I am getting anywhere. Should I change his diet back to wet food? Which food is best? I am at my wits end as this has gone on too long. Any suggestions would be highly appreciated.
