Can Cats Eat Raw Fish? – No, They Can’t

When it comes to feeding your feline friend, you might think that raw fish is a natural choice. However, it is a no; cats should not eat raw fish. While cats in the wild might consume fish, the raw fish we buy is not the same. It can have bacteria and parasites dangerous to a cat’s health. Plus, raw fish contains an enzyme which breaks down thiamine, an essential B vitamin for cats, which could lead to serious health problems.

Can Kittens Eat Raw Fish?

Similarly, in the case of kittens, the answer remains a no. Kittens have an even more sensitive digestive system than adult cats. At this stage of their life, they require nutrition that is specific to their developmental needs, and raw fish can pose a risk of deficiencies and infections that their young bodies are not equipped to handle.

Things to consider when feeding raw fish to kittens?

Even though you should avoid feeding raw fish to kittens altogether, it’s important to note that their dietary requirements are different from those of adult cats. They need more protein, amino acids, and vitamins which come from specially formulated kitten food, rather than the unbalanced source that raw fish could be.

Nutritional Benefits of Avoiding Raw Fish for Cats – Why Cats Shouldn’t Have Raw Fish

Prevent Thiamine Deficiency

Sparing your cat from raw fish protects them from thiamine deficiency, which can cause severe neurological issues and even lead to convulsions or comas if not treated properly.

Avoid Parasitic Infections

By not feeding cats raw fish, they are less likely to encounter parasitic infections such as anisakiasis, which can cause gastrointestinal problems or more serious health issues.

Reduce The Risk of Food Poisoning

Food poisoning from bacteria like salmonella is much less of a concern when raw fish is excluded from a cat’s diet. These bacteria can cause diarrhea, vomiting, and a loss of appetite in cats.

Ensure A Balanced Diet

Avoiding raw fish helps ensure that cats receive all their nutrition from a balanced diet specifically formulated for them which includes all necessary vitamins, minerals, and proteins.

Maintain Healthy Digestion

By steering clear of raw fish, cats are more likely to maintain a healthy digestive system free from the unwholesome consequences associated with fish not intended for raw consumption.

Potential Allergies: Can Cats Be Allergic to Raw Fish?

Yes, cats can be allergic to raw fish. Fish is one of the top allergens in cats. An allergic reaction occurs when a cat’s immune system mistakenly identifies fish proteins as a harmful substance.

Symptoms of Raw Fish Allergies in Cats

  • Itchy Skin: Look out for excessive scratching or grooming.
  • Gastrointestinal Distress: Symptoms like vomiting or diarrhea can indicate an allergy.
  • Respiratory Issues: Difficulties in breathing or wheezing may also be a sign.

What to Do If Your Cat Shows Symptoms?

  • Consult a Veterinarian: Always seek professional advice to diagnose and treat allergies.
  • Elimination Diet: Under veterinary guidance, removing raw fish from the diet can help to identify if it’s causing the problem.
  • Medication: A vet may prescribe antihistamines or steroids to alleviate symptoms.

Recommended Amount: How Much Raw Fish Can a Cat Consume?

Considering the risks, it is recommended to avoid raw fish in a cat’s diet altogether. Feeding cats cooked fish occasionally, in small, controlled amounts, is a safer option if you wish to give them a treat.

Things to Consider When Feeding Raw Fish to Cats

Although it’s best to avoid feeding raw fish to cats, if you decide to feed fish, it should be thoroughly cooked and deboned. Fish should only be offered in moderation as part of a balanced diet.

How to Feed Fish to Cats: A Quick Guide

If you’re eager to treat your cat with fish, it’s essential to do this safely. Cooked fish can be a tasty treat for your furry friend when prepared properly. Here’s how to do it:

Cooked Salmon Cube Treats

Boil or steam a piece of fresh salmon until it’s fully cooked. Cut it into small, bite-sized cubes and ensure there are no bones. Cool the cubes before serving to your cat as a special treat.

Mashed Tuna Toppers

Take a can of tuna in spring water, drain it, and then mash up the tuna. Spread a small spoonful onto your cat’s regular dry food to enhance its flavor and nutritional profile.

Baked Whitefish Delights

Choose a white fish like cod, bake it thoroughly in the oven, and flake it apart. Make sure the fish is without added oils or seasoning. Mix the flaked fish with a bit of your cat’s usual wet food.


In conclusion, while the sight of cats munching on raw fish might appear charmingly natural, it’s best left in the cartoons. The risks associated with feeding raw fish to cats and kittens are substantial, ranging from nutrient deficiencies to viral and parasitic infections. A cat’s health is best supported by a balanced diet tailored to its nutritional needs, which can, from time to time, include suitably prepared fish. Always consult your veterinarian for the best dietary advice tailored to your cat’s unique health profile.
