Updated November 20th, 2020
This page is a companion to our articles on homemade low carb diets for cats and the problems with commercial cat foods.
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).

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.

Hi Andrew,At the moment I am feeding balanced raw,I use Raw Meow mix,you add it to muscle meats.My cats are thriving.Its just costing me soooo much.I also feed cans,but they just not keen on many.My dog is fed Delicate Care dry food made in WA and bones three times a week.Was thinking of moving cats to Delicate Care dental diet,I worked out 42 per cent carbs.Both cats this year have had bloods and both perfect.Such a minefield.Tried Ziwipeak,Feline Naturals,just won’t eat.So basically not sure what to do
Hello, thank you so much for your blog. I’ve been reading all your posts to educate myself as a new kitten mama. I’ve just adopted at 10 week old kitten and have been feeding him Dine Kitten (Tuna, Chicken) and Felix Kitten (variety of flavours). I can’t see these in your list and was wondering if they are ok? If not can you suggest a better alternative?
Hi Tracy. I think from memory Dine didn’t publish enough information on their packets to be able to make the assessment, and Felix is made by Purina, which means you can get an idea from looking for that on the chart. Of course, there is the carb calculator if you have decent information on the packet but you need all of those parameters present.
Hi Dr Andrew,
Thank you for your informative article. I just have a couple of questions.
1. What is an acceptable range of carbohydrate content in commercial foods? I assume the less carbs the better but what % is considered too high?
2. My cats love raw meat. Can I mix raw meat in with a low carb tinned food so that the important vitamins, minerals and taurine missing from the raw meat are included?
Hi Corinne. This is tricky to answer. “Acceptable’ depends a lot on the cat, as most will tolerate carbohydrates even at the extreme levels we see of 35%. Ideally they would be up to 10%. Regarding raw meat, it actually does contain taurine but you are right that too much will cause an imbalance in other nutrients. I would keep this to below one quarter of the diet.
Hi Andrew,
I was just looking at a Science Diet can for Urinary and Hairball Control. ‘Savory Chicken Entree’
It says :
Crude protein 7%
Crude fat 3.5%
Crude fiber 1.5% Minimum, Maximum 4%
Moisture 78%
Going by the calculations this should be fine?
Thank you!
Patty
I get 30-40% carbohydrate if I assume ash to be 1%. This is of course only a rough estimate.
Hi Andrew, I found your post today and wondered how current it is? An amazingly helpful list, thank you! I have a diabetic cat so have moved her off the dry food and onto FF pate. But I am concerned that you rate the Chicken/Giblet pate as 9% carbs, when other research I have done suggests it is much lower – around 2%. This makes it all very confusing! The USA has so many pate choices, yet here in Aust it is very limited, so good to see the PRO PLAN variety is ok too. I might try it. Thank you again
Hi Penny. The list is less than six months old. If you have conflicting data, I would be very interested to see them, as this is information not usually supplied by the manufacturers. The numbers I report are estimates – I have explained how I arrived at these figures in the text so you can check them yourself.
Hi Andrew, I was going by Dr Lisa Pierson’s chart which I have also found extremely useful – I wonder if you know it?
It certainly is a minefield out there!
Thanks again for your time.
