Welcome to FDMB. Sounds like Tiger has quite the cattitude nipping you when he wants more food! Tiger may have gained back the weight he lost, but is he now at his ideal weight? How are his BG levels? Unregulated cats can't get all the nutrition out of the food they take in so sometimes they do need a bit more than the suggested portions. How often do you feed him? If you are feeding him twice daily, which many vets advice, that may be part of the problem. Many if not most of us here, divide food up over several meals/snacks per day to keep kitty satisfied. What kind of insulin are you using? That too may be playing a role in Tiger's seemingly insatiable appetite.
Are you home testing Tiger's BG levels? If so are you using a human or pet meter? We strongly advocate doing this to keep Tiger safe and it might also give you more insight into exactly when he is most hungry and why. BG levels are constantly fluctuating and kitties that are running high want food as do kitties who are running low. If BG levels are only checked at the vet, they can often be elevated due to stress leading the vet to prescribe more insulin than is really needed. This in turn causes the body's defense system to pump out hormones to raise the blood sugar levels and cause more hunger.
If we can get you to set up a signature (the lighter grey text below my post) with the info I asked about (type of insulin, dose, if you are home testing what meter you use) as well as Tiger's diet info, any other health concerns, date of diagnosis and perhaps your location (state, province, country) so that if you need any purchasing assistance we can provide pertinent info, your name, and anything else you think we need to know, it will be on each of your posts and we won't keep asking you the same questions repeatedly and be able to offer support pertinent to you and Tiger.
To set up a signature, hover you mouse cursor over your user name in the upper right corner of your screen. A menu will drop down and you click on Signature in the left hand column. This opens a text box where you can type in this info. The box only allow 3 lines of text so we separate different bits of info with a "|" or "/" if space becomes an issue.
BTW....I have a non-diabetic feral rescue (mine from 5 days old) and I have come to the conclusion that you can take the kitten out of the feral colony but you can't take all the feral out of the cat. Mine has plenty of cattitude too but I love it!
