Fiber is a type of carbohydrate that isn't digested by a cat's gastrointestinal tract. It is important for cat health, because it provides bulk to move food through. Some types of fiber can be fermented (broken down by bacteria) in the system. This process creates short-chain fatty acids (SCFA), which are an important energy source for the cells lining the intestinal tract.
Today, people are more aware of fiber and its role in their diet. Studies showing the beneficial effects of higher fiber levels in humans influence the way many people think about their own food and that of their pets. Some manufacturers now apply the recommendations of human nutritionists and make high-fiber diets for cats, but cats have a much shorter digestive tract than we do. And unlike humans, cats are carnivorous, so their nutritional needs are better satisfied with meat rather than plant matter. Therefore, cats have different dietary needs than humans. For more than 60 years, companion animal nutritionists at IAMS™ have been studying diets to meet the special nutritional needs of cats.
IAMS Company research shows the optimal crude fiber level for healthy cats ranges from 1.4% to 3.5%. At these levels, nutrient breakdown is maximized. In unique situations, such as hairballs, higher fiber levels may be beneficial.
An important characteristic of fiber is its fermentability, or how well it can be broken down by bacteria in the intestine. This breakdown produces short-chain fatty acids, which provide energy to the intestines. Fiber varies in fermentability. 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. Research has shown that moderate 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 and, therefore, are beneficial in cat diets.
High levels of poorly fermentable fiber are used in some weight-reduction pet foods to dilute the calories in a serving. IAMS Company research shows that high fiber levels can make it harder to digest other nutrients in the food and, in turn, reduce the nutritional quality of a cat's diet. Your cat making more trips to the litter box can be a result.
When choosing a pet food, fiber is an important consideration, but remember that the needs of cats are not the same as those of humans. A moderate level of moderately fermentable fiber, such as beet pulp, provides proven nutritional benefits for cats. Cat diets containing high levels of poorly fermentable fiber dilute calories and deprive cats of the nutrients they need.
All IAMS products are made with levels of moderately fermentable fiber needed to promote intestinal health. And all IAMS foods, such as IAMS ProActive Health™ Adult Original with Chicken, contain the moderately fermentable fiber system, which is the exclusive property of IAMS Company and is protected by U.S. Patent No. 5,616,569 for Pet Food Products Containing Fermentable Fibers and Process for Treating Gastrointestinal Disorders.
Are you considering feeding a raw diet to your kitten? Before you do, make sure you have the right information. Get the facts about 10 common myths associated with raw meat diets.
FACT: No scientific studies have shown benefits of feeding raw diets to kittens or cats. Their appeal is based on word of mouth, testimonials and perceived benefits.
FACT: Lynxes and other animals in the wild, like wolves, do eat raw meat (in addition to berries, plants, etc.). However, the average lifespan for an animal in the wild is only a few years. Therefore, what is nutritionally “optimal” for a wild animal like a lynx is not optimal for our pets that we hope will live longer and healthier lives.
FACT: Cats, especially kittens, senior cats or immunosuppressed animals, can become infected with Salmonella, Clostridium, Campylobacter and other bacteria found in raw meat diets, just as people can.
FACT: Even meats purchased at the best stores for people can contain harmful bacteria, so purchasing “human-grade” meat does not protect against the health risks of uncooked meats. (Ask yourself: Would you eat raw ground beef?) It is also important to keep in mind that the term “human grade” has no legal definition for pet food.
FACT: Most of the bacteria found in raw meat diets can easily survive freezing and freeze-drying.
FACT: Bones, whether raw or cooked, can fracture your kitten’s teeth. They also can block or tear the esophagus, stomach or intestine.
FACT: All the enzymes dogs and cats (and people) need for digestion are already in the gastrointestinal tract. Additional enzymes from food are not required for digestion.
FACT: Corn, oats, rice, barley and other grains are healthy ingredients that contain protein, vitamins and minerals; they are not added as fillers and are unlikely to cause allergies. Although meat is an important component of diets for kittens and cats, grains can be part of a high-quality, nutritionally balanced diet.
FACT: Byproducts are the animal parts American people don’t typically eat, such as livers, kidneys or lungs — in other words, the organs and meats other than animal muscle. Note that some pet foods may actually list these ingredients (e.g., duck liver, beef lung), but these are really just byproducts. Most commercial and many home-prepared raw diets also contain by products.
FACT: Most homemade (and even some commercial) raw meat diets are extremely deficient in calcium and a variety of other nutrients, even if chicken necks, bones or eggshells are added. This can be disastrous for any animal but especially for young, growing kittens, and can result in fractured bones. For complete and balanced nutrition, feed your cat a high-quality kitten food like IAMS™ ProActive Health™ Healthy Kitten.
