Why Do Cats Like Tuna So Much?

Reasons Why Your Cats Like Tuna So Much

Any cat owner knows that their feline friend has a penchant for tuna. In fact, many cats will turn their noses up at other types of food in favor of this seafood favorite. But why do cats like tuna so much?

There are a few theories that attempt to explain this phenomenon. One is that cats are attracted to the strong smell of tuna. Cats have a highly developed sense of smell, and the strong scent of tuna is simply too hard for them to resist.

Another theory is that cats associate tuna with the feeling of being well-fed and content. After all, most cats only eat tuna when they’re feeling particularly hungry. As a result, the smell of tuna becomes associated with happiness and satisfaction.

Whatever the reason, there’s no denying that cats love tuna. And while this seafood can be a healthy part of your cat’s diet, there are also some potential dangers to consider.

The Science Behind Cats’ Love of Tuna

As we mentioned, one theory for why cats like tuna so much is that they’re attracted to the strong smell. But what is it about the smell of tuna that is so appealing to cats?

Well, it turns out that tuna contains a chemical compound called ethylmercaptan. This substance is also found in other seafood, such as shrimp and crab.

Ethylmercaptan has a strong sulfur odor that is very similar to the scent of rotting fish. To humans, this smell is incredibly unpleasant. But for cats, the scent of ethylmercaptan is simply irresistible.

In addition to the appealing smell, tuna also contains a high level of protein. This is another factor that makes it so attractive to cats. After all, cats are carnivores and require a diet that is rich in protein. Tuna is an excellent source of this nutrient, which is why it’s often used as a dietary supplement for cats.

The Health Benefits of Feeding Your Cat Tuna

In moderation, feeding your cat tuna can actually be quite beneficial. As we mentioned, tuna is an excellent source of protein. It’s also a good source of omega-three fatty acids, which are important for maintaining a healthy coat and skin.

Tuna is also low in calories, making it a great choice for cats who are trying to lose weight. And because it’s so high in protein, it can help to build and maintain muscle mass.

So, there are definitely some health benefits to feeding your cat tuna. However, it’s important to remember that this seafood should only be given in moderation.

The Potential Dangers of Feeding Your Cat Too Much Tuna

While most cat owners are aware of the dangers of feeding their pet too much tuna, they may not be aware of the potential consequences. Tuna is high in mercury, which can be toxic to cats in large quantities.

In addition, tuna contains a compound called histidine, which can cause an imbalance in a cat’s amino acids. This can lead to health problems such as liver disease and blindness.

As a result, it is important to feed your cat tuna in moderation. If you are concerned about your cat’s diet, speak to your veterinarian about the best way to ensure that your pet gets the nutrients it needs.

How to Safely Feed Your Cat Tuna?

Cats love tuna, and many owners enjoy treating their feline friends to a delicious can of fish every now and then. However, it is important to feed tuna to your cat safely in order to avoid any potential health problems.

First of all, only offer fresh or canned tuna that is intended for human consumption. Avoid giving your cat tuna that has been processed into cat food, as this may contain harmful ingredients.

When preparing the tuna, be sure to remove all bones and skin, as these can cause choking or blockages. If you are feeding your cat canned tuna, make sure to drain off the oil or water before giving it to your cat.

And always offer tuna as a special treat rather than a regular part of your cat’s diet. By following these simple guidelines, you can safely enjoy giving your cat the occasional treat of tuna.

Alternatives to Tuna for Your Cat

Cats are obligate carnivores, meaning that they require animal protein to survive. Tuna is a common source of protein for cats, but it is not the only option.

Other seafood, such as salmon, shrimp, and crab, can also be a healthy part of your cat’s diet. You can also find cat food made with chicken, turkey, beef, or lamb. If you’re looking for a vegetarian option, there are some brands of cat food that use soy or pea protein.

Ultimately, the best food for your cat is one that meets their nutritional needs and is palatable to them. Talk to your veterinarian about the best diet for your feline friend.


Now that you know the answer to the question, “Why do cats like tuna so much?” you can make sure that your cat enjoys this delicious seafood in a safe and healthy way. Remember to feed tuna in moderation, and offer other protein-rich foods as well. With a little bit of care, you can keep your cat happy and healthy for years to come.
