Even if a cat food is formulated to provide all of the essential nutrients, it is of little value if the cat won’t eat it. Quality cat foods are carefully formulated not only to be highly nutritious, but to be highly palatable as well.
Palatability is a term used to describe how well a cat likes the taste, smell, and texture of a food. A premium pet food manufacturer spends a considerable amount of time conducting controlled feeding studies to determine the right combination of ingredients and processing techniques to produce a nutritious, palatable food.
There are two ways to test and measure the palatability of cat food:
First bite: The first palatability test is called the first bite preference, and measures the cat's first impression of a food's aroma and appearance.
Total volume: Because the novelty of a new diet can cause highs and lows in first bite tests, a second test, the total volume measurement, is conducted. Total volume determines the staying power, or ability of a diet to maintain the animal's interest over time. This is the cat's overall choice of food based on taste, texture, and nutrition for the entire test period.
In order to obtain and interpret accurate results, palatability studies must be performed by experienced animal technicians, with data analyzed by research nutritionists. Feeding studies are conducted by offering an animal two bowls of food at the same time. Each bowl contains a different diet that has been carefully weighed and recorded.
The technician observes which food the animal chooses to eat first, then records that as the first bite preference. After a specific time period, bowls are removed and any remaining food is weighed and recorded. Diets are also switched from left to right each day of the study to ensure that animals are not eating one diet simply out of habit.
The total volume measurement is determined by calculating the difference between the beginning and ending weights of each food. This procedure is repeated using the same two diets with the same group of dogs or cats for five days. At the end of the five-day study, all observations and data are compiled and analyzed to determine the overall palatability of each diet.
Cats are attracted by not only the taste of a food, but also by the sight, aroma, and texture. Cats can be very particular about the shape and size of dry food kibbles and also prefer a food with an acidic taste.
Liquid digest is simply protein that is enzymatically broken down into amino acids, which are the building blocks of protein. The enzymatic process reduces large protein pieces to smaller protein pieces and free amino acids. By adding small amounts of acid, the enzymatic or digestive reaction is stopped, and a stable liquid ingredient is produced. After a dry food formula is cooked, formed into kibbles, and dried, the liquid digest is sprayed evenly on the outside of the dry kibbles. This is called enrobing. Not only does the liquid digest make the food highly palatable, but it also adds to the overall digestibility of the food.
Yes. We use liquid digest made from chicken to enhance the palatability of dry foods and to contribute to the nutritional value of the diet. Some pet foods include flavor enhancers, such as onion powder, which simply mask the aroma and taste of the ingredients and provide no nutritional benefits to the animal.
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 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.
