it could just be a case of "repeat speak" commonly found on message boards, but prevailing wisdom these days seems to be to feed a diabetic kitty "as much as they want". overfeeding may be ok if kitty is underweight, but many of our diabetics are "fluffy" to begin with. i felt it was time to resurrect an old post from Dr. Lisa referencing a prior FDMB post by Hilary/Zug for your thought and consideration: Feeding hungry..... unregulated cats Posted by: Lisa dvm (IP Logged) Date: April 11, 2009 02:42AM Vic is right when she is discussing a happy medium. From this link: http://www.felinediabetes.com/phorum5/read.php?15,520791,532240 Please see this post: why food should be somewhat controlled... Posted by: Hilary & Zug(GA) (IP Logged) Date: December 1, 2006 11:22PM 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. from: http://lbah.com/feline/diabetes.htm#Pathophysiology 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!". Hilary Me: Active (albeit intermittently) on FDMB since Dec 2002. Zug (GA): B&W Japanese Bobtail, unknown age. Diagnosed 12/18/02. Tightly regulated on PZI-VET for most of his fight with diabetes.
