There is no reason to be concerned if your dog eats your cat’s wet food on occasion or if it is an accident. Wet cat food does not contain any toxic ingredients for dogs. A few days of upset stomach is the worst you can expect. However, most dogs probably won’t even get that far. |
In this article you will know the answer to the query “My Dog Ate Wet Cat Food“.
You would have encountered your dog eating your cat food if you were lucky enough to live in a household with a dog and a cat.

Canot they just help themselves?
This article will take a very detailed look at how damaging it is for dogs to eat wet cat food.
Nevertheless I want to share a few statistics that demonstrate just how much we love our dogs and cats.
No matter how hard I try I can not find any figures that indicate how many households in the US or UK own a dog and a cat.
According to a UK study from 2020 more than 10 million adults own either a dog or a cat but there was no information on households that own both kinds of pets.
The figure of 10 million adults represents about 25% of the adult population in the UK.
In the United States 63% of households own a dog and 42% of households own a cat.
This means that there are about 89 million dogs and 94 million cats in the United States.
The most pressing issue is now on my mind.
My dog ate wet cat food? What should I do?
There is no reason to be concerned if your dog eats your cats wet food on occasion or if it is an accident.
Wet cat food does not contain any toxic ingredients for dogs. A few days of upset stomach is the worst you can expect.
However most dogs probably would not even get that far.
The wet cat food bowl will have been wolfed down by them and no harm will have come to them except that their owner will be cross with them afterward.
They would have enjoyed it so much they will look forward to the next time you turn your back on them.
It is because wet cat food contains almost the same vitamins and minerals as wet dog food that it will not harm your dog.
Its just that each of these has significant differences in quantity and proportion.
As a one-off accident you should not worry too much if your dog eats a piece of wet cat food just keep poop bags on hand!
A can of wet cat food instead of dog food can be fed to your dog as an occasional emergency.
Donot make it a habit because there are important differences between vitamins and minerals.
If you are out of canned dog food and you need an alternative try boiling chicken and rice.
I hope I have eased your nerves with that information.
I want to discuss the differences between wet cat food and wet dog food in the next section.
Whats the difference between wet cat food and wet dog food?
There are good ways and bad ways to go about this and I have done both!
Let me first show you how to find out the key differences between dog food and cat food.
Next I will show you how to do it wrong- which might be a bit of fun for those of you who are more detail-oriented!
Differentiating between dog food and cat food the right way
There is an organization in the US called the Association of American Feed Control Officials (or the AAFFCO) that determines what types of nutrients should be included in a healthy dog diet and what types of nutrients should be included in a healthy cat diet.
Each nutrient is listed along with how much a dog or cat needs.
In addition as the nutritional requirements of a dog or cat change as they age the AAFFCO has developed a list of nutrients for puppies or pregnant dogs and one for adult dogs.
In the same way there is a list for kittens and pregnant cats and another for adult cats.
I will compare the nutritional requirements of adult dogs and adult cats in this article as this is a comparison of dog and cat foods.
Nutrition needs adult dog vs adult cat
Adult Dog | Adult Cat | ||
Protein | 18% | Protein | 26% |
Fats | 5.5% | Fats | 9% |
Minerals | Includes calcium phosphorus potassium sodium chloride magnesium iron copper manganese zinc iodine selenium | Minerals | calcium phosphorus potassium sodium chloride magnesium iron copper manganese zinc iodine selenium |
Vitamins | Includes vitamin A vitamin D vitamin E thiamine riboflavin pantothenic acid niacin pyridoxine folic acid vitamin B12 choline | Vitamins | Includes vitamin A vitamin D vitamin E vitamin K thiamine riboflavin pantothenic acid niacin pyridoxine folic acid vitamin B12 choline biotin |
A comparison of vitamins and minerals needed by an adult cat or an adult dog
As we can see from the chart adult dogs require a completely different amount of protein and fat in their diet than adult cats.
Dogs require their food to contain 18% protein and 5.5% fat while adult cats require 26% protein and 9% fat.
Additionally the information in the vitamins and minerals columns is inaccurate.
From a superficial perspective it appears that adult dogs and adult cats both require the same minerals.
According to the charts they clearly do.
When you dig a little deeper however you will find that the exact amounts of minerals are different for dogs and cats.
Its true that we’re talking about tiny differences but if the wrong food is consistently fed to a dog or cat this will harm them in the long run.
With vitamins the situation is a little different.
It is not necessary to add vitamins to the diet of a dog but cats need two vitamins.
This vitamin is vitamin K and this vitamin is biotin.
Nutrition needs puppies vs kittens
Puppies | Kittens | ||
Protein | 22.5% | Protein | 30% |
Fats | 8.5% | Fats | 9% |
Minerals | Includes calcium phosphorus potassium sodium chloride magnesium iron copper manganese zinc iodine selenium | Minerals | calcium phosphorus potassium sodium chloride magnesium iron copper manganese zinc iodine selenium |
Vitamins | Includes vitamin A vitamin D vitamin E thiamine riboflavin pantothenic acid niacin pyridoxine folic acid vitamin B12 choline | Vitamins | Includes vitamin A vitamin D vitamin E vitamin K thiamine riboflavin pantothenic acid niacin pyridoxine folic acid vitamin B12 choline biotin |
A comparison of vitamins and minerals needed by puppies and kittens
In comparing the nutritional needs of puppies and kittens protein and fat content are completely different.
While puppies need 22.5% of their food to be protein and 8.5% to be fat kittens need food with a 30% protein content and 9% fat.
Cats and dogs like their adult counterparts need vitamins and minerals added to their diets but when it comes to the exact amounts each vitamin and mineral requires they differ quite a bit.
According to recommendations kitten food should contain 75 mg of zinc per kilogram and puppy food should contain 100 mg of zinc per kilogram.
Vitamin A is essential to kittens at 6668 IU per kilogram and puppies at 5000 IU per kilogram.
Of course you can argue that these are tiny amounts and therefore very small differences but over time.
In my opinion reviewing the information provided by AAFCO is the best way to determine the important differences between dog food and cat food.
However I will show you how to do things the wrong way in the next section.
I tried this way first and unfortunately it did not work.
The wrong approach to determining the difference between wet dog food and wet cat food.
Studying the labels of canned dog and cat food is not the right way to do this.
Its true- I’m nerdy as hell.
Minerals and vitamins are all I have looked at so far.
In order to compare the wet cat food with the wet dog food I will first compare the wet cat food with the wet dog food.
A second important question I would like to ask regarding wet cat food is whether it contains anything that might harm or be toxic for your dog?
How does wet cat food differ from each other?
I examined two different cans of cat food from two different companies. Friskies and 9Lives are two popular brands.
The following chart displays all the important information.
Minerals and Vitamins in wet cat food: Friskies vs 9 Lives
Minerals | Minerals | Vitamins | Vitamins |
Friskies | 9Lives | Friskies | 9Lives |
Potassium chloride | Potassium chloride | B1 | B1 |
Zinc sulfate | Zinc Oxide | B2 | B2 |
Ferrous sulfate | Ferrous sulfate | B3 | |
Manganese sulfate | Manganese Oxide | B5 | B5 |
B6 | B6 | ||
Copper sulfate | Copper sulfate | B7 | B7 |
Potassium iodide | B9 | B9 | |
Sodium Tripolyphosphate | B12 | B12 | |
Choline Chloride | E | E | |
Carrageenan | A | A | |
Calcium iodate | K | ||
Sodium selenite | D3 | D3 | |
Sodium nitrate |
Lets think about the minerals first.
Both cans of food contain three minerals.
The following are their names:
Potassium Chloride
Ferrous sulfate
Copper sulfate
Minerals such as these are in both cans of cat food so they can be considered essential to its diet.
Both cans of food also contain two minerals that are very similar (but not exactly the same).
Zinc sulfate and manganese sulfate are found in Friskies cans.
Unlike 9Lives which contain zinc oxide and manganese oxide.
Blue highlights these areas.
Whats interesting is why one manufacturer uses sulfates while the other uses oxides.
Its a question I can not answer!
The last six minerals are only found in the can of 9Lives wet food not in the can of Friskies.
The following are their names:
Sodium Tripolyphosphate
Choline Chloride
Carrageenan
Calcium iodate
Sodium selenite
Sodium nitrate
These minerals do not appear in either can of food so they cannot be considered essential to a cats diet.
How does wet dog food compare with each other?
As shown in my chart below I compare two different brands of dog food – Pedigree and Natures Recipe.
Pedigree Choice Cuts vs Nature’s Recipe
Minerals | Minerals | Vitamins | Vitamins |
Pedigree | Nature’s Recipe | Pedigree | Nature’s Recipe |
Potassium Chloride | Potassium Chloride | Choline chloride | Choline chloride |
Magnesium sulfate | Magnesium sulfate | Vitamin E | Vitamin E |
Zinc sulfate | Zinc sulfate | Thiamine mononitrate B1 | Thiamine mononitrate B1 |
Copper proteinate | Copper proteinate | Calcium pantothenate B5 | Calcium pantothenate B5 |
Potassium iodide | Biotin B7 | ||
Manganese sulfate | Manganese sulfate | Riboflavin B2 | Riboflavin B2 |
Selenium | Vitamin A | Vitamin A | |
Copper sulfate | Copper sulfate | Vitamin D | Vitamin D |
Zinc protein | Vitamin B12 | Vitamin B12 | |
Ferrous sulfate | Vitamin C | ||
Iron proteinate | Niacin B3 | ||
Manganese Proteinate | Folic Acid B9 | ||
Calcium iodate | B6 | ||
Sodium Selenate |
Taking a look at the minerals first both brands of canned dog food contain the same six minerals.
The following are their names:
Potassium chloride
Magnesium sulfate
Zinc sulfate
Copper proteinate
Manganese sulfate
Copper sulfate
Minerals are a vital part of a dogs diet and since they are in both cans of food it is safe to conclude that they are an essential part of it.
Eight more minerals can be found in either Pedigree food or Natures Recipe but not both.
The following are their names:
Potassium iodide
Selenium
Zinc protein
Ferrous sulfate
Iron proteinate
Manganese proteinate
Calcium iodate
Sodium Selenate
The fact that these minerals are not in both cans of food suggests that these minerals are considered essential in dogs’ diets.
Regarding vitamins there are eight that are contained in both food cans.
Here they are:
Choline chloride
Vitamin E
B1
B5
B2
A
D
B12
Since these are both food cans these vitamins should be an important part of a dogs diet.
Besides the five vitamins in the Natures Recipe and Pedigree food cans there are five more vitamins not found in both.
Here are the five vitamins:
B7
Vitamin C
B3
B9
B6
Due to the fact that these five vitamins only appear in one can of food they cannot be considered an essential part of a dogs diet.
What is the difference between wet cat food and wet dog food?
Now we reach the crux of the matter the most important question.
Therefore in order to get some sort of answer I will use only the minerals and vitamins that both brands of wet dog food and wet cat food provide.
Minerals | Minerals | Minerals | Minerals |
Wet Dog Food | Wet Cat Food | Wet Dog Food | Wet Cat Food |
Potassium Chloride | Potassium chloride | Thiamine mononitrate B1 | B1 |
Zinc sulfate | Zinc sulfate | Riboflavin B2 | B2 |
Copper sulfate | Copper sulfate | Calcium pantothenate B5 | B5 |
Manganese sulfate | Manganese sulfate | Choline chloride | B6 |
Magnesium sulfate | Ferrous sulfate | B7 | |
Copper proteinate | B9 | ||
B12 | B12 | ||
E | E | ||
A | A | ||
D | D3 |
The chart above shows that both canned dog food and canned cat food contain lots of vitamins and minerals.
Compared to the differences there are more similarities.
Of the seven minerals in either wet dog food or wet cat food four of them are included in both.
Here they are:
Potassium chloride
Zinc sulfate
Copper sulfate
Manganese sulfate
The other three minerals can only be found in canned dog food or canned cat food.
There are only two found in dog food- magnesium sulfate and copper proteinate.
The only one that appears in cat food is ferrous sulfate.
As far as we are concerned is ferrous sulfate toxic for dogs if it is not in dog food but is in cat food?
The answer to this is that in the amounts found in cat foods it is not toxic to dogs.
Are magnesium sulfate and copper proteinate toxic for cats since they are not in cat food?
Thats not true.
Looking at the chart it is clear most vitamins can be found in both wet cat food and wet dog food.
Among the eleven vitamins found in canned dog and cat food seven are found in both kinds.
There are seven vitamins in total: A B1 B2 B5 B12 D and E.
The only source of choline chloride is dog food.
However the amount that is present in canned dog food is not toxic for cats
Only cat food contains vitamins B6 B7 and B9. Vitamins are not toxic to dogs in the amounts that are found in canned cat food.
Does anyone regulate what goes into pet food?
Pet food is regulated by the Food and Drug Administration in the United States.
There seem to be four elements to it.
Safe to eat
Produced insanitary conditions
Contain no harmful substances
Labeled truthfully
In almost every state the department of agriculture is responsible for more regulation than the FDA.
Indeed these departments appear to play a much more active role in making sure pet foods are safe on a daily basis.
Food Standards Agency is responsible for regulating pet food in the UK.
However I was unable to find any clear guidance on what is and isnot allowed in the manufacture of dog or cat food.
We have discussed who regulates the industry in this section but we havenot discussed who decides what a healthy diet for dogs and cats should contain.
This is the responsibility of AAFFCO (Association of American Feed Control Officials).
Cats and dogs need specific nutrients in their food which is listed by the ASPCA.
Each nutrient is listed along with how much a dog or cat needs.
In addition as the nutritional requirements of a dog or cat change as they age the AAFFCO has developed a list of nutrients for puppies or pregnant dogs and one for adult dogs.
In the same way there is a list for kittens and pregnant cats and another for adult cats.
In an article comparing dog and cat foods I will compare the nutritional requirements of adult dogs with those of adult cats and puppies with those of kittens.
Adult Dog | Adult Cat | ||
Protein | 18% | Protein | 26% |
Fats | 5.5% | Fats | 9% |
Minerals | Includes calcium phosphorus potassium sodium chloride magnesium iron copper manganese zinc iodine selenium | Minerals | calcium phosphorus potassium sodium chloride magnesium iron copper manganese zinc iodine selenium |
Vitamins | Includes vitamin A vitamin D vitamin E thiamine riboflavin pantothenic acid niacin pyridoxine folic acid vitamin B12 choline | Vitamins | Includes vitamin A vitamin D vitamin E vitamin K thiamine riboflavin pantothenic acid niacin pyridoxine folic acid vitamin B12 choline biotin |

In comparing the nutritional needs of puppies and kittens protein and fat content are completely different.
While puppies need 22.5% of their food to be protein and 8.5% to be fat kittens need food with a 30% protein content and 9% fat.
In general cats and dogs require the same vitamins and minerals added to their food as adults do however when it comes to the amount of each vitamin and mineral to be consumed the amounts differ quite a bit.
As an example every kilogram of kitten food should contain 75 mg of zinc whereas each kilogram of puppy food should contain 100 mg of zinc.
Vitamin A is essential to kittens at 6668 IU per kilogram and puppies at 5000 IU per kilogram.
Of course you can argue that these are tiny amounts and therefore very small differences but over time.
Can you describe what a complete diet is and how it relates to wet food?
The majority of the dog (or cat) food cans are described as “complete”. So your dog only needs to eat a small amount of canned food to survive and thrive.
Nothing else needs to be fed to them.
Hence wet dog food contains added vitamins and minerals to make sure that a dog gets everything it needs.
The majority of dry dog foods (kibble) are also complete and contain added minerals and vitamins.
