Determining calories in wet food?

How I determine the amount of kcal in canned wet food? Is there a mathematic equation?

Thanks

There is a mathematical equation but you would have to call the food companies to get 'as fed' values
Here is how you do it This is for carbs but you would calculate the same way for anything

This list has foods where this was aleady done so maybe you can be spared the phone calls and math

you may still need to figure as the second link info is a few to many yrs old and even has a disclaimer about it
