How much food?

[Barbara Carella]

My cat Simon is about 14 years old and was diagnosed with diabetes two years ago. He is on ProZinc. How much food should I be giving him per day?

Enough to maintain his weight if hi is at the weight he should be. A little more if you want him to gain weight and a little less if you want hit to lose weight.
The rough estimate is 20 to 30 kcal per day per pound of body weight.
I use a digital postal package scale to weigh mine.
