Updated November 20th, 2020
Carbohydrates are the only major nutrient not to be declared on cat foods. Therefore, I’ve done three things:
- Created an online carbohydrate calculator for wet and dry pet foods
- Estimated the carbohydrate levels in a wide range of pouch or tinned foods
- Showed you how I worked out these figures
Pet Food Carbohydrate Calculator
Note: as you will see later, these figures are only estimates. They are hopefully close to the truth but cannot be verified without analysis.
Carb Levels In Adult Cat Foods
Please Note: I have not included:
- The nearly 50% of can and pouch cat foods sold in Australia that aren’t complete foods. Click the link to learn more.
- Any dry foods- these all contain carbohydrate levels between 20 and 35%
- Foods that do not disclose either the carbohydrate level, or protein, fat, ash & fibre levels so I can work it out (e.g. Feline Natural)

I have avoided supermarket own-brands and ‘special’ diets like light, hairball, indoor, urinary, senior etc).
* Moisture not declared so given average value of 78%
** some numbers seem impossible; the first three have ingredients adding up to 100.7%, 100.5% & 100% respectively before carbs are considered (my guess is that actual moisture levels are lower than the ‘max’ figures supplied).
Carbs In Kitten Foods
|Food||Carbs as %DM (est)|
|PRO PLAN Kitten Chicken & Liver Entree||2.1|
|Fancy Feast Kitten Whitefish Feast tin||4.6|
|Royal Canin Kitten Instinctive in Loaf*||10.9|
|Hill’s Kitten Liver & Chicken Entrée tin||15|

|Royal Canin Kitten Instinctive in Gravy*||17.7|
|Hill’s Kitten Tender Chicken Dinner tin||19.2|
|Hill’s Kitten Roasted Chicken & Rice Medley||28.9|
Kitten foods are much harder. Many companies just don’t offer them.
How to find out the carbohydrate content of your cat’s food
This is the same method I used above- it may slightly overestimate the true level but should be within a few percent.
Most foods have a Guaranteed Analysis. Weirdly, it doesn’t include carbs, but that’s OK; you can work them out from everything else.
Let’s use the Grain Free Blackhawk as an example. I’m not saying it’s any better or worse than other foods.
- Add up the %Crude Protein, Crude Fat, Ash, Crude Fibre and Moisture (34+16+3.5+8+10=71.5)
- Subtract this number from 100% (100-71.5=28.5)
- The carbohydrate level is approximately 28.5% (It’s not going to be exact but should be close)
This is as fed. To be able to compare wet and dry foods, let’s make it as a % of dry matter.
- Turn the moisture percent into a fraction (10% = 0.1. A wet food would be around 80% = 0.8)
- Subtract this from 1 (1-0.1=0.9. With wet foods, you’ll get a number around 0.2)
- Divide the nutrients by this number (28.5 / 0.9 = 31.7%).Remember these numbers are only estimations.
