The Importance of Taurine in Cat Food

 

Taurine is an important component to all IAMS™ cat foods, such as IAMS ProActive Health™ Adult Original with Chicken. Taurine is an essential amino acid that is critical for normal heart muscle function, vision, and reproduction in kittens. It is also needed to form the bile salts that aid in digestion. Unlike other amino acids, taurine is found as a free amino acid in body tissues such as the heart and eyes, and is not incorporated into proteins.

Most mammals manufacture taurine from other amino acids. However, cats cannot manufacture a sufficient amount and, therefore, must acquire enough additional taurine through diet to meet their needs. In pet food, taurine is naturally found in animal-based protein ingredients and can also be added separately.

 

Why Does IAMS Add Taurine to Cat Diets?

Taurine is supplemented in IAMS dry and canned cat foods to ensure that we provide optimal levels of this essential nutrient. IAMS wet cat foods are supplemented with taurine because they must contain as much as twice the amount of taurine found in dry food for cats to maintain adequate blood taurine levels. The canning process may affect the complex taurine balance in your cat. Our wet cat foods are supplemented with taurine to meet these higher needs.

IAMS dry cat foods also include taurine as an ingredient to supplement the primary source of this amino acid, which is animal-based protein from sources such as chicken, egg, lamb, and fish. However, these sources can vary in their taurine content, and adding more taurine is a sound approach to ensure optimal taurine levels.

 

What Are Some Effects of Taurine Deficiency?

  • Blindness

Taurine is essential to the proper development and function of cells in the retina of the eye. If insufficient taurine is present, the retinal cells don’t function properly and may die, eventually causing impaired vision and even blindness. This process is referred to as feline central retinal degeneration.

  • Heart Disease

Taurine is also necessary for normal function of the heart muscle cells. Taurine deficiency leads to weakening of the heart muscle, which, in turn, can lead to heart failure. This condition is known as dilated cardiomyopathy and can be fatal.

  • Decreased Reproductive Performance and Growth

Taurine is necessary for optimal reproductive and growth performance. Both the queen and kittens must maintain adequate taurine levels during pregnancy, lactation, and growth to ensure proper structural development.

 

Taurine in IAMS Cat Foods

IAMS cat foods are formulated with high-quality, animal-based proteins as their primary ingredient. In addition, they are supplemented with extra taurine to ensure balanced levels of essential amino acids.
