Taurine is an important component found in all IAMS™ kitten foods. This essential amino acid 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, kittens 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 also can be added separately.
IAMS kitten foods are formulated with high-quality animal-based proteins as their primary ingredient. In addition, they are supplemented with extra taurine.
We supplement taurine in IAMS dry and canned cat foods to ensure we provide optimal levels of this essential nutrient. IAMS wet kitten foods, such as IAMS™ Perfect Portions™ Healthy Kitten Paté with Chicken, 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 or kitten. Our wet cat foods are supplemented with taurine to meet these higher needs.
IAMS dry kitten foods, such as IAMS™ ProActive Health™ Healthy Kitten, 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.
Kittens that eat a diet deficient in taurine can develop several serious health conditions.
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.
Taurine is also necessary for normal function of the heart muscle cells. Taurine deficiency leads to a weakening of the heart muscle, which, in turn, can lead to heart failure. This condition is known as dilated cardiomyopathy and can be fatal.
To help protect your kitten’s health, both now and when she is fully grown, make sure to feed a diet with sufficient taurine. Learn more about the nutritional needs of kittens.

As dogs age, changes occur in the way their bodies function, so it makes sense that what they eat also might need to change. The following list of health issues might be more common in aging pets.
Decreased Immune System Function
Throughout a dog’s life, a process called peroxidation occurs. Peroxidation is a normal process that the body uses to destroy cells that outlive their usefulness and to kill germs, parasites, etc. This process, however, also can destroy or damage healthy cells. As your dog ages, the damage caused by peroxidation accumulates, which, in turn, increases the risk of certain problems, such as infections.
Antioxidants are naturally occurring nutrients that help maintain overall health by neutralizing the peroxidation process of cellular molecules. Some antioxidants, such as vitamin E, beta-carotene, and lutein, are naturally occurring nutrients.
Recent research sponsored by The IAMS™ Company found that dogs fed a diet rich in antioxidants such as vitamin E, lutein, or beta-carotene had improved immune responses and vaccine recognition. This might be especially important in senior dog care; IAMS research has found that as dogs age, immune responses can decrease.
More Frequent Intestinal Problems
Older dogs might have higher numbers of unfavorable bacteria and lower numbers of beneficial bacteria in their intestines, which can result in clinical signs of gastrointestinal problems (e.g., diarrhea).
Feeding a diet containing fructooligosaccharides (FOS), a unique fiber source that helps nutritionally maintain healthy intestinal bacterial populations, promotes growth of beneficial bacteria. Beet pulp, a moderably fermentable fiber source, also helps maintain intestinal health by providing energy for the cells lining the intestine and promoting small, firm stools.
Different dogs show signs of aging at different times, and much of this variation is associated with size. Larger dogs generally appear 'old' sooner than smaller dogs. The table below lists the age at which various groups of dogs should be transitioned to senior foods, such as IAMS™ ProActive Health™ Senior Plus.
| Weight Range | Age to Begin Transition |
|---|---|
| More than 90 lbs | 5 years |
| 51 to 90 lbs | 6 years |
| 21 to 50 lbs | 7 years |
| Up to 20 lbs | 7 years |
