just wanted to share a post from the past that sheds a whole lot of light on feeding diabetic kitties...

Vic is right when she is discussing a happy medium.

why food should be somewhat controlled...

Here's a really good explanation of why NOT to overfeed/feed until "satisfied":
In general, brain cells do not need insulin to utilize glucose. A specific area of the brain, called the appetite center (in the hypothalamus), monitors the amount of glucose that circulates in the bloodstream. The lower the blood glucose level in the cells in the appetite center the greater the appetite. Unlike most of the brain cells, the ability of glucose to enter the cells of the appetite center is dependent upon insulin. In diabetes mellitus, with its lack of adequate insulin in the bloodstream, these appetite center cells don't monitor glucose levels properly, thinking the blood glucose is low. as a result, the pet develops polyphagia to correct for this perceived problem. The additional food that is then eaten further increases the blood glucose level.

Basically, a cat that's unregulated can't really tell what's going on with its appetite, and the high BGs make the cat even hungrier. It's something of a balancing act -- you want to be sure you're feeding sufficient food that the cat is getting the nutrition it needs, especially to help reduce the risk of ketoacidosis, but you don't want to overfeed (which often happens when the cat is "hungry"). The poor cat doesn't know if it really needs food, it just knows that its brain is saying "need food now!".

feeding diabetic cats "as much as they want" will often result in grossly overweight kitties. their caregivers end up having to put the cat on a "diet".
Dr. Lisa has put together some great info here: Feline Obesity: An Epidemic of Fat Cats. Definitely worth reading.
