Mackerel is a type of oily fish that is often canned and consumed as a protein-rich food. It’s an excellent source of omega-3 fatty acids, which are important for maintaining a healthy coat, reducing inflammation, and improving joint function. Many people wonder if it’s safe to give their cats mackerel.

Cats are obligate carnivores, which means that they require animal protein to survive. In the wild, they would get all the nutrients they need from eating whole prey. However, when cats are fed a diet of dry food or canned food, they may not be getting all the nutrients they need. Adding mackerel to your cat’s diet can help them get the nutrients they need and may also have some health benefits.

What is Mackerel?

Mackerel is a type of oily fish that is high in omega-3 fatty acids. It is a popular choice for people who are looking for a healthy fish to add to their diet. Mackerel is also a good source of protein and vitamin B12.

While mackerel is generally considered to be a healthy food for humans, you may be wondering if it is also safe for cats to eat. The answer depends on a few factors, including whether your cat has any allergies or medical conditions that could be aggravated by eating fish.

As with any new food, it is always best to introduce mackerel (or any other fish) to your cat slowly and in small amounts. This will help you to gauge whether or not they are tolerate it well. If your cat does not have any adverse reactions after eating mackerel, then it is probably safe for them to eat on a regular basis.

The Benefits of Mackerel for Cats

Mackerel is a type of fish that is high in protein and omega-3 fatty acids, making it an excellent food for cats. It can be fed to cats as a regular part of their diet, or as a occasional treat.

There are several benefits of feeding mackerel to cats. The high protein content helps to keep them healthy and fit, while the omega-3 fatty acids can help to improve their skin and coat condition. Furthermore, feeding mackerel to cats can also help to reduce hairballs, as the fish oils can help to make their fur more manageable.

The Risks of Feeding Mackerel to Cats

While mackerel is a nutritious and delicious type of fish for humans, it can be dangerous for cats. Mackerel is high in mercury, which can cause neurological problems in cats. It’s also high in sodium, which can lead to dehydration. Cats also have a hard time digesting fish, so feeding them mackerel can cause gastrointestinal issues.

If you’re considering feeding your cat mackerel, talk to your vet first. They can help you determine if it’s safe for your cat and how much to feed them.

How to Feed Mackerel to Cats

Canned mackerel is an easy way to give your cat the seafood she needs. Look for brands that don’t have salt or seasonings added, and offer a variety as part of a rotation diet.

Macronutrients in Canned Mackerel
A five ounce can of mackerel has the following macronutrients, on average:
-Calories: 66
-Protein: 12.5 grams
-Fat: 1 gram
-Carbohydrates: 0 grams
Of these macronutrients, protein makes up the largest percentage at 18.9%.


Yes, cats can eat mackerel, but it is not necessarily the best fish for them to eat. While mackerel is a good source of protein and healthy omega-3 fatty acids, it also contains mercury. Too much mercury can be toxic to cats and may cause health problems. If you do feed your cat mackerel, be sure to give only small amounts as part of a balanced diet.
