Feline Nutritional & Special Health Issues FAQs

Drs. Foster & Smith Educational Staff
  • What is arachidonic acid, and why does my cat need it?

  • Why does my cat need the active form of Vitamin A?

  • Why does my cat need niacin?

  • Does my senior cat have special dietary needs?

Arachidonic acid is one of the essential fatty acids. Dogs can manufacture arachidonic acid from linoleic acid or gamma-linolenic acid. Cats cannot. Arachidonic acid is necessary to produce an inflammatory response. In many cases, such as in allergies, the goal is to suppress the inflammatory response. But in other cases, the response is a necessary means by which the body can protect itself. Arachidonic acid also helps to regulate skin growth, is necessary for proper blood clotting, and is necessary for the reproductive and gastrointestinal systems to function properly. Arachidonic acid is found in animal fats which must therefore be included as part of the diet. Like dogs, cats also require linoleic acid, another fatty acid.

Why does my cat need the active form of Vitamin A?
Cats lack the enzyme which can convert beta-carotene to retinol, the active form of Vitamin A. Therefore, they require a preformed Vitamin A, which is present only in foods of animal origin, and is usually included in cat foods as retinyl palmitate. Deficiencies of Vitamin A are rare, but signs include night blindness, retarded growth, and poor-quality skin and coat.

Why does my cat need niacin?
Many animals can synthesize niacin, a B vitamin, from the amino acid tryptophan. Cats, however, can not manufacture niacin in sufficient quantities, thus require higher amounts in their diet. Niacin deficiencies can lead to loss of appetite and weight, inflamed gums, and hemorrhagic diarrhea.

Special Health Issues

  • If I feed only canned food, what precautions should I take to protect my pet's teeth?

  • Could your food be causing my pet's excess gas?

  • Could your food be causing my pet's loose stools?

If your pet eats only canned food, you'll need to take extra precautions to ensure healthy teeth and gums. Brush your pet's teeth regularly, take your pet to the vet for regular dental exams, and provide your pet with plenty of chew toys and treats (such as rawhide bones) to remove the plaque and tartar that cause tooth decay and gum disease.

Could your food be causing my pet's excess gas?


Could your food be causing my pet's loose stools?


If feeding less food or feeding several smaller meals does not eliminate the problem of loose stools, your cat may have an intolerance to one or more ingredients in the food. You may wish to try a different food.

Remember, periods of loose stools can quickly cause dehydration and deprive your cat's body of necessary nutrients, so be sure to contact your veterinarian as soon as possible.
