Taurine Deficiency in Cats: How It's Diagnosed and Treated

An important amino acid called taurine is crucial to the health and well-being of cats. We discuss the deficiency of this amino acid in this article.

Taurine is a necessary amino acid that is important for several functions in the health and well-being of cats. Sadly, taurine insufficiency is a widespread condition that can cause a number of health problems in cats.

This article will explore the causes, symptoms, and treatment options for taurine deficiency in cats, as well as ways to prevent it from occurring in the first place.


Taurine deficiency in cats is caused by a lack of taurine in the diet or an inability to properly absorb and utilize taurine.

Taurine must come from the diet because cats are unable to synthesize it from other amino acids. Some cat foods, particularly those made with low-quality ingredients or a high proportion of plant-based protein, may not contain enough taurine. Additionally, cats that are exclusively fed a homemade diet or vegetarian diet may not be getting enough taurine.

Certain medical conditions can also lead to taurine deficiency in cats. Gastrointestinal disorders like inflammatory bowel disease, celiac disease, and exocrine pancreatic insufficiency can prevent cats from consuming taurine from their meals in a healthy way. Taurine absorption can also be hampered by some drugs, including metronidazole and sulfasalazine.

Deficiency in taurine may also run in families. Due to a hereditary mutation, some breeds, including Maine Coon cats, are predisposed to the deficiency.

Cat owners are to be aware of the potential causes of taurine deficiency and consult with their veterinarian to rule out any underlying medical conditions that may be contributing to the problem.


A feline Taurine deficiency can cause a number of symptoms, some of which may not be immediately observed. Here are some popular symptoms of taurine:

  • Cardiac issues: The heart needs taurine to function properly, and a deficiency can lead to dilated cardiomyopathy, a condition where the heart becomes enlarged and unable to pump blood effectively.

  • Vision problems: Taurine is essential for maintaining healthy eyes, and a lack of it can cause blindness and retinal degeneration.

  • Digestive issues: The digestive system needs taurine to function properly, and a lack of it can cause nausea, vomiting, and decreased appetite.

  • Reproductive issues: Taurine is needed for proper fertility and the development of healthy kittens.

  • Behavioral changes: Cats that don't get enough taurine may become agitated, worried, or violent.

  • Weakness and muscle atrophy: Taurine is also important for muscle health, and a deficiency can lead to weakness and muscle wasting.

However, some of these symptoms may be caused by other medical conditions, so it's important to consult with a veterinarian if you suspect your cat may have a taurine deficiency.


  • Supplementing the cat's diet with taurine-rich foods, such as meat, fish, or eggs.

  • Giving the cat taurine supplements either as liquid or pills.

  • To decide the right amount of taurine to give the cat, consult a veterinarian.

  • Using prescription diets specifically formulated to provide adequate levels of taurine.

  • Treating any underlying illnesses that might be the source of the inadequacy. For instance, if your vet diagnoses an intestinal issue being the underlying reason behind the deficiency, he may prescribe gastrointestinal medications for cats.

Ways to Prevent Taurine Deficiency

  • Feeding a high-quality, well-balanced diet that includes animal-based protein sources, such as meat, fish, or eggs.

  • Providing a diet that is formulated specifically for cats, as they have unique nutritional requirements.

  • Monitoring the cat's diet to ensure they are getting enough taurine and other essential nutrients.

  • Consultation with a veterinarian to ensure the cat's diet is appropriate for its age, health, and lifestyle.

  • Regular check-ups with a veterinarian to detect any early signs of deficiency and address them promptly.

  • Avoid vegetarian or vegan diets, as cats are obligate carnivores. They have to have animal-based protein in their diet to be able to maintain their health.

  • Monitoring the cat's overall health and addressing any underlying medical conditions that may affect taurine levels.

In conclusion, cats who are taurine deficient may have a variety of health issues, such as heart disease and blindness. However, cat owners may contribute to ensuring the long-term health and well-being of their furry friends by taking the required precautions to prevent taurine insufficiency.
