Can Maine Coon Cats Eat Mackerel?

Do you have a Maine Coon cat as a pet? If so, you may be wondering if it is safe for them to eat mackerel. In this post, we will explore whether or not Maine Coon cats can eat mackerel and share some tips on how to incorporate this fish into their diet.

Can Maine Coon Eat Mackerel?

Maine Coon cats can eat mackerel as long as it’s given on occasion and a part of a well-balanced diet. Mackerel is quite nutritious for cats but it lacks the essential nutrients needed for cats to grow strong and healthy. This is why it’s best to only give your Maine Coon mackerel occasionally.

Health Benefits of Mackerel For Cats

Mackerel is a fish that is high in omega-3 fatty acids, which are beneficial for cats’ health. Omega-3 fatty acids help to improve skin and coat health, joint health, and heart health in cats.

Mackerel is also a good source of protein and vitamins B6 and B12.

So based on the nutritional info alone mackerel is actually great food for your cat.

Omega-3 Benefits

The health benefits of omega-3 fatty acids in cats are many. Omega-3s play a critical role in maintaining your cat’s health.

They are beneficial in preventing and treating a wide range of diseases, including:

  • Cancer
  • Heart disease
  • Arthritis
  • Inflammatory bowel disease
  • Diabetes

Omega-3s are also important for cognitive function and vision.

Protein Benefits

The health benefits of protein for cats include good muscle development, strong bones, and healthy skin and fur.

Protein is essential for cats, as they cannot produce it on their own and must get it from their diet.

Indeed, cats are obligate carnivores which means they live on animal-based proteins.

Protein is also important for helping cats maintain a healthy weight.

Vitamin B6 and B12 Benefits

Vitamin B6 is an important vitamin for cats and has a number of health benefits, including:

  • Helping to maintain normal blood pressure
  • Supporting the health of the heart and circulatory system
  • Helping to maintain a healthy appetite
  • Supporting the nervous system

Additionally, B12 is important for cats’ overall health. Vitamin B12 helps keep cats’ energy levels up, supports their immune systems, and is essential for healthy nerve function.

By providing your cat with a diet that includes plenty of Vitamin B12, you can help ensure that they stay happy and healthy!

However, we should look at some of the health risks associated with too much mackerel in your cat’s diet.

Health Risks of Mackerel For Cats

The health risks of mackerel for cats are as follows:

Mackerel can contain high levels of thiaminase. This is an enzyme found in some seafood that breaks down Vitamin B.

This can stop your cat from obtaining Vitamin B from their diet and lead to Vitamin B deficiency.

Thankfully, this is only an issue in raw mackerel so if you want to avoid this make sure you give your cat cooked mackerel.

Additionally, mackerel is a very oily fish. Fish oil can inhibit a cat’s ability to absorb Vitamin E which can lead to Vitamin E deficiency.

Symptoms of Vitamin E deficiency in cats can include:

  • Muscle weakness
  • Lethargy
  • Poor appetite
  • Weight loss
  • Heart dysfunction
  • Liver Hepatitis


Make sure you reach out to your veterinarian if you see any of these symptoms in your cat.

If a cat is allergic to mackerel, it could experience an upset stomach or diarrhea.

If you see these symptoms after your cat eats mackerel, it’s best to avoid giving them mackerel and look for alternative snacks for your furbaby.

Mackerel Alternatives

There are many other fish and snacks you can feed your Maine Coon if you’re looking to spice it up a bit:

Whats The Best Mackerel For My Cat?

Canned Mackerel

When choosing canned mackerel it’s best to always choose mackerel in water. Additionally, go with the unsalted version.

The main goal when buying mackerel for your Maine Coon cat is to minimize salt and oil.

This also means not buying mackerel in oil. Mackerel is a very oily fish anyway so feeding a cat mackerel in oil only adds an unnecessary amount of oil.

Raw or Cooked Mackerel

Cats do not have the same enzymes that humans and dogs do when it comes to digesting fish.

This makes eating raw fish dangerous because it leaves them vulnerable to pathogens and other harmful enzymes.

While cooked fish is safe, it can still be a choking hazard if your cat swallows a large bone. So make sure to remove any bones before serving.

Can Maine Coon Cats Eat Mackerel In Tomato Sauce

Tomato sauce adds extra sugar that may make your cat ill.

It’s best to avoid giving a Maine Coon mackerel in tomato sauce and instead opt for mackerel in unsalted water.

Can Maine Coon Cats Eat Mackerel In Olive Oil / Sunflower Oil

Mackerel is already an oily fish so adding olive or sunflower oil only makes it even more oily.

It’s best to avoid giving cats too much oil in general. The best type of mackerel is canned unsalted mackerel.

Can Maine Coons Eat Mackerel Skin and Bones

Maine Coon cats can most certainly eat the skin of mackerel. So if youre thinking of taking the skin off the fish before serving, don’t bother.

Bones shouldn’t be served to cats. It doesn’t matter if they’re cooked or uncooked. Bones are a choking hazard and can become lodged in your cat’s throat.

However, some people like to grind the bones down into dust and sprinkle them into a meal.

Bones are a great source of calcium for your cat that helps keep their bones strong and healthy.


So, while mackerel is a great source of protein and vitamins for your cat, it’s important to be aware of the health risks associated with feeding them too much.

Make sure you reach out to your veterinarian if you see any symptoms in your cat that may be related to a deficiency in one of these vitamins.

Additionally, there are many other fish and snacks you can feed your Maine Coon if you’re looking to spice it up a bit.
