Fiber isn’t just for humans — it’s an important part of balanced nutrition for cats, too!
But how much fiber do cats need, what kinds should they be eating and how can you make sure they’re getting the right amount for their bodies?
Cats and humans both need fiber in their diets, but that doesn’t mean cats should be eating the same amount as humans. People are growing more aware of the importance of fiber in our own diets today — and while it’s good to think about your cat’s fiber intake too, it’s important to remember that cats have different dietary needs than humans.
Cats have a much shorter digestive tract than humans, and unlike humans, cats are carnivorous, so their nutritional needs are better satisfied with mostly animal-based ingredients rather than plant matter.
Nondigestible fiber supports cat health by providing bulk that helps move food through the digestive system. This fiber is largely made up of carbohydrates that cats can’t break down in the same way they digest protein or fat. This undigested matter helps usher food through your cat’s system at a healthy pace that lets them absorb the nutrients in their food and eliminate waste comfortably. Higher levels of nondigestible fiber can even help address specific conditions like frequent hairballs.
Fiber can’t be broken down and digested like proteins and fats, but some kinds can be fermented (broken down by bacteria) in your cat’s digestive system. This breakdown produces short-chain fatty acids, which provide energy to your cat’s intestines as it is fermented.
Fiber sources used in pet foods include cellulose, which is poorly fermentable; beet pulp, which is moderately fermentable; and gums and pectin, which can be highly fermentable. Appropriate levels of moderately fermentable fiber, such as beet pulp, provide the benefits of energy for the intestinal lining and bulk without the negative effects of excessive stool or gas. That makes them ideal for the health and comfort of most cats!
While a high-fiber diet can be part of a weight-loss solution for humans, our research has found that it’s not as helpful as a weight-reduction option for cats.
High levels of poorly fermentable fiber in cat food dilute the calories and nutrients in a serving and may make your cat feel fuller. Unfortunately, high fiber content can also increase the rate at which food passes through your cat’s digestive tract, making it harder for them to digest other nutrients in their food. They may be going to the litter box more often, but that doesn’t mean their digestive system is working more efficiently.
When choosing a pet food, remember that cats and humans need different things from their food. All IAMS™ cat food products are made with the right amount of moderately fermentable fiber needed to promote intestinal health. Use the IAMS™ Cat Food Selector to find a recipe tailored to your cat’s unique needs.
The Association of American Feed Control Officials (AAFCO) was formed in 1909 to establish a framework for uniform regulation of the feed industry. Although not a government agency, AAFCO operates within the guidelines of federal and state legislation including laws administered by the Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA).
AAFCO establishes standards or models for regulations aimed at ensuring that manufacturers provide clear, accurate, and consistent information about animal feed, including pet food.
Every year AAFCO issues an official publication called the AAFCO Manual. This manual, in addition to listing ingredient definitions and feed terms, addresses labeling issues such as label format, ingredient lists, nutrition claims, and guaranteed analysis.
These model regulations are different from laws. However a large number of state governments have adopted AAFCO pet food model regulations into state law.
The “AAFCO statement of nutritional adequacy or purpose,” also called a “nutrition claim” or “complete and balanced statement,” identifies which life stage and/or lifestyle the product has been approved for. Under AAFCO regulations, this statement must be substantiated by the manufacturer.
AAFCO recognizes three methods for substantiating the claim:
1. Laboratory analysis
2. Feeding trials
3. Analysis comparable in nutritional adequacy
AAFCO has outlined very specific protocols, or guidelines, for conducting feeding tests. The protocols specify test criteria including such things as:
Each life stage has its own protocol. Life stages are the same for both dogs and cats and are defined as:
A pet food with an 'All Life Stages' claim can be used from weaning through adulthood. This claim is considered an unqualified (absolute) representation of nutritional adequacy. If substantiated through feeding trials, the protocol for gestation/lactation and growth must be performed sequentially, using the same group of animals.
AAFCO regulations state that specific wording must be used when a diet is intended for special nutritional or dietary needs that require the involvement of a veterinarian for diagnosis, management, and follow-up.
Understanding the AAFCO statements for nutritional adequacy can help customers choose a high-quality diet that provides complete and balanced nutrition for the appropriate life stage of their dog or cat.
