> Maybe I'll just do the 1/2 dose next time if I can even draw up 1/2 dose
Just a thought: You may want to pick up some u100 syringes. Vetsulin is a u40 insulin, but you can give it using u100 syringes -- just multiple the dose you want to give by 2.5. For example, to give 1 unit, you would draw insulin to the 2.5u line; to give half a unit, you would draw halfway between the 1 and 1.5u line.
Benefits: as you may have discovered, u40 syringes are generally only available through vets, special orders, and the internet. The needles are generally long and big, and kinda expensive. u100 syringes are easily available at any pharmacy, less expensive, can come in shorter and thinner sizes for your cat's comfort -- and, if you pick up syringes with half-unit markings, are very useful for accurately giving smaller doses of insulin.
