In the end, your cat will be eating 60-70% fewer calories in a day, decreasing the calories intake in cats. 

The Crystal Ball Method

The formula is designed to calculate the cat and the number of calories you takedown in this method. The formula is:

(13.6 x W) + 70

The Intuition Method 

This method is straightforward and requires common sense only. Undoubtedly helpful for a person who does not like calculations. It requires you to decrease the cat’s food intake every day, little by little. However, it is essential to understand the nutrient deficit cats face when cutting down the calories.

For the changes in the diet because you cannot reduce the protein and nutrients quantity in the feline’s body.
