Can Cats Eat Mackerel? – Yes, They Can

Cats are natural hunters and meat-eaters, and mackerel can be a tasty and nutritious addition to their diet. Rich in essential nutrients, this type of fish can offer several health benefits to cats when served properly. Still, it’s important to ensure it is given in moderation and prepared safely to avoid any potential risks, such as bones that could cause choking or harm.

Can Kittens Eat Mackerel?

Yes, kittens can also eat mackerel, but always with extra caution. Since their digestive systems are still developing, it’s pivotal to introduce any new food, including mackerel, gradually and in small amounts. Monitoring the response of your kitten to mackerel is necessary to account for any signs of digestive upset.

Things to consider when feeding mackerel to kittens?

When introducing mackerel to a kitten’s diet, consider the size and frequency of the portion. Start with a tiny piece to see how they handle it and ensure the fish is thoroughly cooked and free of bones. Since kittens require a balanced diet to grow, mackerel should only be an occasional treat and not a staple of their diet.

Nutritional Benefits of Mackerel for Cats – Why Mackerel is Good for Cats

Omega-3 Fatty Acids

Mackerel is high in Omega-3 fatty acids, which can support a cat’s immune system, reduce inflammation, and promote a shiny, healthy coat. These essential fats are also critical for healthy brain development in kittens.

This fish is a good source of B vitamins, which help in energy production and prevent medical issues like heart disease by controlling homocysteine levels in the blood.


Mackerel contains essential minerals such as phosphorus for healthy bones and selenium, an antioxidant that helps in maintaining a robust immune system.


An amino acid crucial for a cat’s health, taurine is abundant in mackerel. It aids in vision, digestion, and heart muscle function.
