Cats need taurine because they can't produce enough of this essential amino acid themselves, making it vital for their heart, vision, digestion, reproduction, and immune function; without it, they risk serious conditions like blindness, heart failure (DCM), and developmental issues, as taurine is found only in animal-based proteins and supports key bodily processes.
This amino acid can't be made in their body because cats don't have the enzymes needed. As a result, cats require taurine daily as part of their diet. Taurine is found in most animal proteins like meat, liver, and eggs, and is easily obtained from naturally occurring prey such as fish, birds, and rodents.
Taurine is a component of bile salts, and its deficiency may cause digestive disturbances. If caught early enough, dilated cardiomyopathy may be reversible with dietary supplementation. Left untreated for too long, it will progress to heart failure and death.
The results showed that to maintain plasma taurine values in the 'normal' range (less than 60 mumol/l), a canned diet must supply at least 39 mg taurine/kg body-weight per d and a dry diet at least 19 mg/kg body-weight per d; a cat fed on a semi-purified diet need only achieve a daily intake of at least 10 mg taurine/ ...
Low levels of taurine have been associated with neurotransmitter imbalances. These can manifest as symptoms such as mood swings, anxiety, depression, and cognitive decline.
For commercial pet food, the minimum taurine requirement for adult cats is 25 mg/100 kcal of dry food and 50 mg/100 kcal for canned foods (The Association of American Feed Control Officials Publication, 2021).
Shellfish
The most abundant source of taurine comes from the ocean. Shellfish are some of the most highly concentrated sources of taurine. Research on the amount of taurine in shellfish varies based on the sample. But scallops (827 mg) and mussels (655 mg) usually contain the most.
The top "silent killers" in cats are Chronic Kidney Disease (CKD), often progressing until 75% kidney failure, and Hypertrophic Cardiomyopathy (HCM), a heart muscle disease, both often showing few symptoms until advanced stages, along with Hypertension (High Blood Pressure) and Hepatic Lipidosis (Fatty Liver), leading to sudden illness or organ failure if undetected. Early detection through regular vet check-ups, blood tests, and monitoring for subtle changes like increased thirst/urination, weight loss, or hiding is crucial for managing these common, often hidden, feline diseases, says this article.
One of the most commonly reported side effects of taurine is gastrointestinal discomfort. Some users may experience symptoms such as diarrhea, constipation, stomach cramps, or bloating. These symptoms are usually mild and tend to resolve on their own without the need for medical intervention.
Cats source taurine from raw meat, with muscle meats (including heart) having the highest levels. So the best way for them to intake taurine naturally is to include raw meats in their diet.
Cats with taurine deficiency may also experience digestive issues, such as poor digestion and nutrient absorption. Taurine plays a role in bile salt formation, which is necessary for fat digestion. Symptoms of digestive problems include diarrhea, weight loss, and a dull coat.
Cats fed 60% soybean protein or casein diets had significantly lower plasma taurine concentrations than cats fed a 30% casein diet, with the 60% soybean protein diet causing the greater decrease.
At Royal Canin, all our food for dogs and cats include taurine as part of a carefully balanced nutritional mix designed for each specific breed or health requirement.
A taurine deficiency can cause many problems in cats, including: Dilated Cardiomyopathy. The condition causes the heart to enlarge, affecting its ability to pump blood effectively. Cats affected by dilated cardiomyopathy may also develop congestive heart failure as a result of pumping issues.
Other beneficial nutrients of eggs for your cat include: Amino Acids: Eggs come packed with a wide variety of amino acids, most notably taurine. Taurine plays a critical role in boosting vision, digestion, heart function, immunity, healthy pregnancy and fetal development for cats.
Here are some options of nutritionally complete cat foods that ensure your cat gets adequate amounts of taurine:
Recent research has examined the impact of taurine, a popular amino acid often found in energy drinks, on leukemia cells. While taurine is naturally produced in the body and supports various functions, studies suggest that in certain concentrations, it may encourage the growth of cancerous blood cells in lab settings.
So, low taurine levels could potentially indicate a dietary issue or a side effect of medication. Symptoms of low levels of Taurine could include fatigue, weakened immune system, and issues with vision or eye health.
Also, taurine interacts with some medications, such as antidepressants, anti-seizure drugs, statins, and blood thinners. So if you take any of these, talk to your doctor before taking any taurine supplements.
The 3:3:3 Rule: Help Your New Cat Adjust to Their Home The 3:3:3 rule explains some general expectations for the transition process and some tips on how to support your cat through each stage: 3 days for initial acclimatization, 3 weeks for settling in, and by 3 months, they should be comfortable and at ease in their ...
Cancer is the number one killer of cats, so you should be aware of your cat's risks and how to deal with them. Cancer can affect all organs in the body and can show up at any age, but it's most common in older cats. Cancer is caused by genetic predisposition, environmental factors, diet, or lifestyle.
Cat behavior red flags signal potential medical or emotional issues, including sudden changes in eating/drinking, litter box problems, excessive vocalization, increased hiding, aggression, lethargy, or changes in grooming (like overgrooming or stopping). Because cats hide illness well, any significant deviation from their normal routine, such as increased thirst, appetite changes, or unusual hiding, warrants an urgent vet visit to rule out serious underlying conditions like kidney disease, hyperthyroidism, diabetes, or pain.
Studies have shown that overuse of muscle depletes taurine level and the loss of taurine occurs mostly in the fast-twitch fibers (Dawson et al., 2000; Matsuzaki et al., 2002; Yatabe et al., 2003).
Whether you get it fresh or from a can, tuna is an excellent source of taurine. Though when choosing your fish, darker meat is richer in amino acids than white meat. Some varieties, like yellowfin tuna, contain up to 964 milligrams per 100 grams, while other marine fish have high levels as well.
No. The amino acid taurine, which is an ingredient of Red Bull Energy Drink and other Red Bull products, is not derived from bulls or any other animals. Instead, it is a purely synthetic substance produced by pharmaceutical companies, which guarantees highest quality standards.
