The most important thing you can do for your diabetic cat is get him onto a low carb (less than 10%) canned or raw diet...The "prescription" foods, especially W/D are way too high in carbs and ALL dry food is a problem just because our sugarcats need all the water we can get into them to help protect their kidneys. W/D is 35% carbs....WAY too high and one of the main ingredients in W/D is "powdered Cellulous"....that's a nice way of saying it's
sawdust!
On the website
"Feeding your Cat" there's a lot of great information on why canned or raw is best to feed
any cat in within that site there's a
Food Chart that lists a lot of the foods available and their carb percentage (Column C)
A lot of us feed Friskies pate's or Fancy Feast Classics because they're under 10% carbs and affordable.
The MOST important thing though is if you reduce the amount of carbs you're feeding,
you need to be home testing your cat so you can monitor how dropping the carbs effects the amount of insulin you're giving.
4U is a very high amount for most cats to begin with, but because you're feeding a very high carb food right now, he's probably requiring that high of a dose. By reducing the amount of carbs he's eating, his insulin dose will come down too...maybe quite quickly!
I strongly suggest you get a human meter and test strips and learn to home test your baby. WalMart carries a Relion Brand of meters (about $15) called Confirm and Micro....the strips for those 2 meters are the same and cost $35.88 per 100 strips
We can help teach you how to home test...it's really not hard and by doing it, you're really taking control of your kitty's diabetes. Information is the best thing you can get to fight this disease and home testing is a very valuable part of that information
What insulin are you using??
