Welcome to FDMB!!
We are firm believers in giving you the information you need to make informed decisions. First, a fructosamine test is very useful for diagnosis. Just like a HgA1c, you also need to home test. Frankly, most of the members here rely more on home testing and do not pay the vet for routine fructosamine tests or in office curves. The Libre is helpful in that regard. (I also encourage members to learn how to home test using a glucometer since the one time the Libre fails is when you need it the most.) Many members use the Walmart Relion meter since the strips are the least expensive around. (Although, as long as your husband doesn't mind, you can borrow his meter!)
Given your description of Boots appetite, it doesn't sound like she's regulated yet. It's not surprising -- it takes a while to get a kitty regulated. We hope to see that BG levels are in the normal 50 - 120 range. Once numbers are lower, Boot's will be less ravenous.
What are you currently feeding Boots? We strongly encourage a low carbohydrate, canned food diet. We consider low carb to be less than 10% although most members feed their cats 5% carb, give or take. This is a
link to a food chart we rely on since it has the nutritional values for most canned foods listed. Just to add, most vets do not like to see a diabetic cat in normal numbers. They leave a very wide margin for safety. However, given that we are advocates of home testing, you have the tools to ensure that your cat is safe and you can use higher carb food to steer numbers if they are dropping into lower ranges. Most vets do not encourage their clients to home test. We also have many cats who have gone into remission and their diabetes is diet controlled.
Weakness in the hind legs is typically the result of diabetic neuropathy. Methylcobalamine (methyl-B12) can be very helpful in mitigating the effects of neuropathy.
Zobaline is a brand that's available on Amazon and is formulated specifically for diabetic cats (i.e., no sugar). Vitacost also sells methylcobalamin in bulk. You just add it to your cat's food. The combination of getting your cat better regulated and the supplement will help considerably in reversing the neuropathy.
We also encourage everyone to create a signature that includes basic information about your cat (e.g., data of dx, insulin you're using, any health issues) so we don't keep asking you for the information repeatedly. We also suggest you set up a spreadsheet to track Boots' progress and so we can follow along. The information on how to do his is in this post on
helping us to help you.
The members here are very generous with their time an knowledge. Please let us know how we can help.
