Unlike humans and some other animals, cats cannot synthesize taurine on their own, making it essential to provide it through their diet. This amino acid plays a crucial role in various bodily functions, and its deficiency can lead to severe health issues in cats.

But where does taurine deficiency in cats come from? What does taurine do for cats? How much taurine do cats need? In this blog, we’ll review all the burning questions revolving around taurine for cats.

Is taurine good for cats or is taurine bad for cats?

Yes, taurine is great for cats, but despite its presence in many animal tissues, cats cannot produce taurine internally, making it a crucial dietary requirement. That’s why pet owners need to ensure their cats are getting an adequate amount in their diets.

Symptoms of taurine deficiency in cats

Without sufficient taurine intake, cats may experience a range of health problems:

Dilated cardiomyopathy

Taurine deficiency can lead to the enlargement of the heart, affecting its ability to pump blood effectively and Crossroads Animal Hospital says this condition can result in congestive heart failure.


According to VCA Animal Hospitals, taurine deficiency in cats can cause the retinal cells of the eyes to eventually degenerate, ultimately impairing vision. This condition is referred to as feline taurine retinopathy (or feline central retinal degeneration). If left untreated, retinal degeneration will lead to permanent blindness. One of the taurine benefits for cats is that it will help maintain good eyesight!

Tooth decay

Taurine plays a role in maintaining dental health, and its deficiency can increase the likelihood of tooth decay and oral issues.

Reproductive issues

Cats with insufficient taurine may face reproductive difficulties, including infertility. VCA Animal Hospitals also says that one of the taurine benefits for cats is helping the maintenance of normal pregnancy and fetal development.

Developmental concerns

Kittens born to mothers with taurine deficiencies may experience growth problems and be more susceptible to bone fractures.

Gastrointestinal problems

Taurine aids in the production of bile salts necessary for fat digestion. A lack of taurine can lead to digestive issues such as diarrhea. You can try giving a taurine supplement for cats to help these symptoms!

Hair loss

Taurine deficiency may affect the quality of a cat’s coat, leading to hair loss or poor coat condition.

Immune system disorders

Cats lacking taurine may have compromised immune systems, making them more vulnerable to infections and illnesses.


Taurine helps regulate blood sugar levels, and its deficiency may contribute to the development of diabetes in cats.


Cats with taurine deficiency may appear lethargic and lack energy.

Where does taurine come from for cats?

Taurine for cats can be found in several foods that your cat might love. According to WebMD, the following are some of the most common taurine sources for cats.


These shellfish stand out as one of the most rich taurine sources for cats available. Whether enjoyed cooked or raw, a 100-gram serving of scallops can deliver an impressive 827 milligrams of taurine. Additionally, clams boast around 520 milligrams, while mussels offer up to 655 milligrams per equivalent portion, making them excellent choices for taurine for cats supplementation.


Whether it’s sourced fresh or from a can, tuna is a fantastic taurine for cats source. Opting for darker meat varieties is advisable, as they tend to be richer in amino acids compared to their white meat counterparts. For instance, yellowfin tuna can pack up to 964 milligrams of taurine per 100 grams, with other marine fish also offering high taurine levels. Cod provides about 120 milligrams per serving, while salmon offers 94 milligrams per serving.

Freshwater fish

Fish like tilapia boast significant taurine for cats content. Dark muscle tilapia filets, weighing 150 grams, can contain approximately 972 milligrams of taurine, while white meat offers less than 120 milligrams. Similarly, carp’s dark meat packs around 868 milligrams, and catfish offers nearly 700 milligrams per equivalent serving.

Octopus and squid

Both of these tentacled creatures are great options that are healthy and rich in taurine for cats. A 3-ounce portion of octopus contains approximately 335 milligrams, while squid offers potent levels as well, with around 219 milligrams per serving.

Notable for its high taurine for cats content among animal meats, turkey provides up to 306 milligrams per 100 grams. However, it’s essential to choose dark turkey meat for optimal taurine benefits, as light meat offers a mere 30 milligrams per equivalent portion.


Similar to turkey, chicken offers around 170 milligrams of taurine for cats per 100 grams, with dark meat such as chicken thighs being preferable over lighter options like chicken breast, which provides only 18 milligrams per equivalent portion.


Beef offers a modest yet noteworthy taurine for cats contribution. Consuming two to three servings of beef per week can add about 40 milligrams of taurine to one’s diet, alongside a wealth of other nutrients and amino acids. Despite concerns regarding excessive red meat intake and its association with chronic diseases, moderate consumption of beef can be safely incorporated into a balanced diet.
