Welcome! Please ask all the questions you want! There's a ton of incredibly useful advice on this board.
If you give us a little information about Socks, maybe we can help you figure out what sort of information you need. :smile:
1. What insulin are you using, and what is the dose? Some insulins are good for cats and some are not. Some vets prescribe the wrong insulin, which can impede treatment. Vets can also sometimes start out cats on too high a dose, which can be dangerous and unproductive for treatment.
2. What are you feeding Socks? Like humans with diabetes, diet is key to managing the disease. Diabetic cats need a low carb, canned diet, and there are many commercial foods that fit this requirement. You don't need a prescription food--in fact, most of the prescription diets are actually too high in carbohydrates for diabetics. There is no dry food that is good to feed a diabetic cat.
3. Has your vet discussed home testing with you? Some vets do and some do not. Home testing is the only way to safely monitor your cat's diabetes--there's a ton of advice and tricks here to help you out. It seems hard at first, but it gets very easy once both you and your cat get used to it.
