What is in Starkist Tuna?

Starkist tuna is a convenience food that is sold in cans. It is a tuna fish product that has been cooked and then canned. The tuna is preserved in water or oil, and it often has other ingredients added to it, such as vegetables, herbs, and spices.

The ingredients in Starkist tuna can vary depending on the variety of Starkist tuna that you purchase. For example, the Starkist Tuna Chunk Light in Water product contains the following ingredients: tuna, water, less than 2% of the following: vegetable broth (corn syrup solids, salt, onion powder, carrot powder, celery seed), salt, sugar, natural flavors. On the other hand, the Starkist Tuna Creations Herb & Garlic flavor contains the following ingredients: tuna, water, less than 2% of the following: soybean oil*, garlic*, spices*, lemon juice solids*, onion powder*. As you can see, there are some differences in the ingredients list between these two products.

It is important to note that all of the Starkist tunas contain some form of onion or garlic in them. This means that they are not safe for cats to eat. Cats are unable to process these ingredients properly and they can cause health problems forcats if ingested in large quantities.

Is Starkist Tuna Safe for Cats?

While Starkist Tuna is not toxic to cats, there are a few things to consider before feeding it to your feline friend. Starkist Tuna is high in mercury, which can be harmful to cats if they eat too much of it. It is also important to make sure that the Starkist Tuna you feed your cat is packed in water and not oil, as oil can cause gastrointestinal issues in cats.

Tuna and Mercury

Most of us are aware that some fish contain mercury, and that we should be careful about how much we consume. But did you know that tuna is one of those fish? In fact, canned tuna can contain quite high levels of mercury.

So, what does this mean for our feline friends? Can cats eat Starkist tuna?

The answer is maybe. It depends on a few factors, including the type of tuna, the amount of tuna, and the overall health of your cat.

Here’s what you need to know about feeding your cat Starkist tuna.

types of tuna
There are two main types of canned tuna: Albacore and light. Albacore (or white) tuna generally has a higher mercury content than light tuna. So, if you’re going to feed your cat Starkist tuna, it’s best to choose the light variety.

amount of tuna
Even light tuna can contain high levels of mercury. So, it’s important to feed your cat only small amounts of Starkist tuna as a treat or occasional snack. A good rule of thumb is to give your cat no more than one ounce (28 grams) of Starkist tuna per week.

overall health

Cats with certain health conditions may be more susceptible to the effects of mercury poisoning. For example, cats with kidney disease may not be able to process and eliminate mercury as well as healthy cats. If your cat has a chronic health condition, it’s best to talk to your veterinarian before feeding them Starkist tuna (or any other type of fish).

symptoms of mercury poisoning in cats

Mercury poisoning can cause a variety of symptoms in cats, including:

-Loss of appetite -Weight loss -Diarrhea -Vomiting -Excessive salivation -Muscle weakness -Tremors -Uncoordinated movement -Blindness If you think your cat has ingested too much mercury or is showing any signs of mercury poisoning, contact your veterinarian immediately.

Tuna and BPA

Tuna is a popular food for humans and cats alike, but there is some debate about whether or not it is safe for our feline friends. The main concern revolves around the mercury levels in tuna and the potential for exposure to BPA (bisphenol A).

Mercury is a naturally occurring element that is found in small amounts in the environment. It is also present in some fish, including tuna. When fish consume mercury, it can build up in their bodies over time. When humans (or cats) eat fish that contains mercury, we can also be exposed to this potentially harmful element.

BPA is a synthetic compound that is used in the manufacturing of certain plastics and canned goods. It has been shown to leach into food, and there is some concern that it could be harmful to both human and animal health.

While there are some risks associated with tuna consumption, the benefits may outweigh these concerns for some pets. Tuna can be a healthy source of protein and omega-3 fatty acids, which can help support a healthy coat and skin. If you choose to feed your cat tuna, it is important to do so in moderation and to select a product that is low in mercury and free of BPA.

How Much Starkist Tuna Can Cats Eat?

Most people think that since tuna is a fish, it must be good for cats. However, this is not necessarily the case. In fact, feeding your cat too much tuna can actually be harmful.

While tuna does contain some nutrients that are beneficial to cats, such as protein and omega-3 fatty acids, it also contains mercury. This can be detrimental to your cat’s health if they eat too much of it.

The amount of tuna that is safe for your cat to eat will depend on their size and weight. For example, a ten pound cat could eat up to two ounces of canned tuna per day. However, a five pound cat should only eat one ounce per day. If you are unsure how much tuna your cat can safely eat, check with your veterinarian.

In addition to the mercury concerns, another thing to consider is that most canned tunas are packed in oil. This oil can cause digestive upset in some cats and should be avoided if possible. If you do feed your cat canned tuna, be sure to drain and rinse the fish well to remove as much of the oil as possible.

Starkist Tuna as a Treat

Starkist Tuna can be a healthy treat for your cat, but only in moderation. Starkist Tuna is a good source of protein and omega-3 fatty acids, which can be beneficial for your cat’s coat and skin. However, Starkist Tuna also contains mercury, which can be toxic to cats in large amounts. When feeding Starkist Tuna to your cat, make sure to give them only a small amount as a treat, and avoid feeding them tuna every day.


After doing some research, we have come to the conclusion that it is not recommended to feed your cat Starkist tuna. While tuna is not poisonous to cats, it can cause health problems if they eat it on a regular basis. Cats are obligate carnivores and their bodies are not designed to process plant-based proteins like those found in tuna. In addition, canned tuna often contains high levels of mercury which can be harmful to your cat’s health. If you want to give your cat a treat, there are many other options that are both safer and more nutritious.
