Our boy, Roops was dx with diabetes sometime in January of this year. We had 3 blood curve tests done at the vet's office. He started out with 1 unit of Prozinc and gradually moved up to 5 units because his numbers were not coming down. We continued this dosage. At some point we noticed a weakness in his back legs. We eventually asked the vet if this could be neuropathy. Prior to this when we noticed a favoring in his back legs... we asked the vet what was wrong. he suggested inflammation. We were right. It was neuropathy. Since then the neuropathy has become increasing worse despite receiving treatment. It is to the point where we carry him up/down the stairs if we hear him, lift him up onto chairs and other furniture. He walks a few steps and lays down to rest. He walks at most 5 feet before laying down. It has now advanced to his front legs. We have not begun giving him B12 but hope to find a equivalent to zobaline soon. To the best of our knowledge Zobaline is not available up here, and is not shipped up here. We have begun testing his blood at home. Prior to his insulin shot in the morning, his blood sugar was about 18.9earlier this week. A fair bit lower (33+) than when he was first diagnosed, or during blood curves at the vet's office in January, February and March. No doubt the stress of being in a strange place and the car ride there and back elevated his blood sugar levels. We are now slowly decreasing the dosage amount believing he may be on too high of a dose. We are currently giving him 4 units every 12 hours. We are also trying to ween him off dry kibble. Currently he is getting Purina Pro Plan Vet OW management kibbles and Friskies pate. He gets treats like Temptations sparingly. My question...is it possible that an overdose or too high of a dose of insulin taken on a daily basis could make his neuropathy worse over time. Also aside from B12 is there anything that can be given to diabetic cats with neuropathy. We were giving him B12 but the wrong kind. Injection type. Aside from not eating wet canned cat food there is nothing else I can think of that we have not done, or are not doing. thank you for your help.
