    So, I'm confused. I have the can here and I put the values into the online calculator and it spits out 12.7% carbs. That said, ash is not written on the can...

    Dr. Lisa says 5%. I'd much rather Dr. Lisa be right, my cats love this flavour. What am I missing here? Is Turkey & Salmon acceptable for Emmett?

    When I look at the can, it comes to 5.4%. BUT someone on chewy asked about carb content and this is what they responded "
    The carbohydrate content for this formula is 1.33% as fed and 5.69% on a dry matter basis"

    I'd take a look at the numbers you were using. This food should be perfect for Emmett!

    I'd go with Dr. Lisa's data. She contacted companies directly and is very knowledgeable about feline nutrition.

    I am sticking with Lisa's chart for sure. But please share how you get 5.4. The can also doesn't list Ash...so none of the online cat food calculators work.

    Haha, honestly just trying to understand. :)

    I see you are in Canada, but I'd think the food is the same. So, here is what the can says:
    Protein 10.5%
    Moisture 78%
    Taurine .1%
    Fiber 1%
    Fat 5%
    So 100-94.6= 5.4 carbs

    I think the label info is what's called the "guaranteed analysis" and it doesn't necessarily translate to % carbs from calories as fed. That's the problem. Dr. Pierson's chart lists % carbs from calories as fed.

    Ya, totally. So I was using these calculators (both have the same results)

    http://scheyderweb.com/cats/catfood.html

    http://www.diabeticcatinternational.com/knowledge/calculating-carbs/ (http://diabeticcatinternational.com/wp-content/uploads/2014/11/Carb-Calculator.xls)


    (From the site above)

    Calculating the Carbohydrates
    In order to illustrate the calculations below, the following values are used:

    • Protein: 10,5%
    • Fat: 5,0%
    • Fibre: 1,0%
    • Ash: ????%
    • Moisture: 78,0%

    1. In order to calculate the carbs on a wet matter basis:

    • Add up the % values for protein, fat, fibre, ash and moisture
    • Subtract the total from 100
    • The difference is the percent carbs on a wet matter basis

    Using the values in the example above:

    • 10.5 + 5.0 + 1.0 + 0.1 + 78 = 94.6
    • 100 – 94.6 = 5.4
    • Wet matter carbs: 5.4%

    2. In order to calculate the % carbs on a dry matter basis:

    • Subtract the % Moisture from 100
    • Divide the percent carbs on a wet matter basis by that number
    • Multiply by 100

    Using the values in the example above:

    • 100 – 78 = 22
    • 5.4 divided by 22 = 0.2454
    • 0.056 x 100 = 24.54
    • Dry matter carbs: 24.54%


    This is what has me confused....

    To note, Dr. Lisa says this in her document:

    Users of the old chart will notice that dry matter values (the weight of a nutrient) have been removed in order to streamline the chart and to make it look less overwhelming. The other reason is because, nutritionally-speaking, looking at the composition (the distribution of protein, fat, and carbohydrate) of food is best done on a calorie (energy) basis not a ‘weight’ basis.


    ...the diabetic page is telling me to go with dry matter below 10% (when turkey & salmon seems to be 24.54% dry matter carbs) whereas Dr. Lisa says it has 6% from TNA calories as consumed. And says that this is the value that should be below 10%. Which turkey and salmon is at 5.4% wet carbs.

    So do we no use the dry matter carb % anymore?

    This is what I'd go by. You can drive yourself nuts with these analyses ... o_O
