I wanted to thank everyone who takes the time to read this post and gives any advice/info. Out 9 year old Male Neutered Cat, Brulee, was diagnosed with diabetes around 2 years ago. He has lived with it managed well, but had a hypoglycemic incident while the caretaker gave him insulin after he had vomited. We have tried adding food to his diet, but he is just skin and bones at this point and have heard multiple diagnosis from multiple vets. We had a T4 test taken that showed his thyroid levels were a little low. We thought that was strange because low thyroid levels normally lead to weight gain rather than loss, but is showing all other clinical signs of hypothyroidism. After this, we went to a separate vet for a second opinion who though the problem may have been Endocrine Pancreatic Insufficiency. After another panel of blood work, the test came back that he was not experiencing anything out of the ordinary with his pancreas (other than diabetes). We placed him on some B12 vitamins and a digestive enzyme to possibly help with malabsorption, but he does not seem to be putting on any weight for as much as we feed him. He is also quite ravenous. He will begin to meow an hour before we feed him and eat all of his food within a matter of minutes. we have done home testing and his glucose drops to a low of about 240 before beginining to climb back up before eating again.
