Cats like eating sardines, despite the fact that they do not engage in aquatic hunting or fishing in the wild. The fact that certain foods that humans eat may be harmful to cats causes their owners to ponder whether or not it is okay to give their cats sardines.

Since of their high protein content, sardines are beneficial to the health of cats because they can be broken down into energy-rich amino acids by cats. In addition, they include minerals like as calcium, copper, iron, phosphorus, selenium, and zinc, all of which are essential for maintaining a healthy coat and internal organs in cats. Due to the significant amount of water that sardines contain, they are also beneficial for hydration.

Fish are abundant in protein, which is why cats like eating them. However, you should only give your cat sardines on a very occasional basis, and you need to make sure that any extra oils, sauces, or brine are drained from the can before doing so. The sardines that are canned in spring water are the best.

In the same way that they like eating other kinds of fatty fish, cats adore sardines.

Cats, for some strange reason, do not hunt in water, and feral cats do not consume fish. Therefore, it is not known how they become used to the flavor of eating fish.

Because of the need for a diet rich in protein in a cat’s food, cats virtually exclusively consume meat. The quantity of protein found in fish is comparable to that found in white and red meats.

Protein, vitamins, and minerals may all be found in abundance in sardines. However, tinned sardines could include bones in them; however, these bones are often rather thin and pliable, so your cat shouldn’t have any trouble digesting them.

There is also the question of whether or not the brines, oils, and sauces that sardines are preserved in are harmful to one’s health. As long as one does not drink an excessive amount, it ought to be OK to use any sort of sauce or oil.

First, you should drain the sardines so that you may reduce the amount of sauce or oil that your cat consumes. It is best to give your cat sardines that have been soaked in spring water and have no additional salt if you want to prevent your cat from consuming an excessive amount of sodium or fat.


When consumed in moderation, cats may safely consume sunflower oil.

Therefore, there is no cause for alarm if you give a cat one sardine that has had the majority of its sunflower oil removed from it. Olive oil and sunflower oil are both completely safe for cats to consume.

However, consuming high amounts of any oil, including sunflower oil, might result in diarrhea. It will also cause your cat to gain weight over time, so be sure not to give it too much of it.

The same is true for sardines that have been preserved in olive oil, which, despite their improved quality, should not be ingested in excessive amounts.


The word “brine” really refers to saltwater. Brine is used to conserve food since it has been used for centuries and has the ability to preserve food.

Unfortunately, cats should not consume salt since it might cause their blood pressure to become too high (hypertension). Therefore, you should try to limit the amount of brine your cat consumes.

A cat that is generally healthy shouldn’t have any problems eating one sardine that has been preserved in brine, but you should still wash it off beforehand.

Choking Hazard

There is a possibility that canned sardines include bones, but even if they do, these bones won’t be too big for a cat to manage, unless your cat is exceptionally little. Even so, your feline friend will gnaw through the sardine and eat around any bones that are too large for her to swallow.

Mercury Poisoning

A study that was published in the Journal of Toxicology and Environmental Health found that cats whose diets included tuna were more likely to have high mercury levels.

Poisoning with mercury has a negative impact on the internal organs of cats, and if pregnant cats consume it, it may have a negative impact on the development of their kittens. Naturally, your cat won’t get enough mercury if it just eats one or two sardines, so don’t worry about that.
