? Diabetic cat weight gain

Has anyone had a problem with their cat gaining weight on insulin. Rico just keeps gaining weight. He only gets fed 2x a day.

 

How much are you feeding per day and what is Rico's ideal weight?
How much is the increas and over what time period?

 

He gets about a 1/2 cup of food a day. He used to weigh 17lbs before he lost weight. He was down to 9lbs before the insulin. Now he just looks like he gained probably 20lbs. Could the purina dm food cause it

 

Vet says his ideal weight is about 15lbs

 

Are you feeding canned or dry DM?

Once cats are in better BG numbers, they do tend to regain some of the weight they may have lost. When their numbers are high, none of what they are eating is getting into their cells so they lose weight. Insulin helps the breakdown of food into glucose get into the cells so the kitty puts on the weight that's been lost. However, the switch to a low carb diet also can cause a cat to lose weight since it's a species appropriate diet -- cat's are obligate carnivores and don't need carbs. If you're feeding Rico a low carb diet and he's still gaining weight, you will need to slowly reduce the amount you're feeding him.

 

If that is dry DM then the cat should not be gaining since Purina recommends 1/2 cup daily for a 12 lb cat.
