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.
Antioxidants are good for your cat because they play a key role in minimizing damage to cells, including cells of the immune system.
These important, naturally occurring nutrients help maintain health by slowing the destructive oxidative process of cellular molecules. They also can be important in supporting immune responses and vaccine recognition in cats. This may be especially critical for kittens that are being vaccinated while their immune system is still developing.
Additionally, antioxidants can reverse decreases in immune-cell function for senior cats, increasing them back to healthy adult levels.
Antioxidants are nutrients found naturally in the body and in plants such as fruits and vegetables. Common antioxidants include vitamin C, vitamin E and certain compounds called carotenoids (including lutein and beta-carotene). A blend of several antioxidants in moderate amounts may be more effective than high levels of one antioxidant.
As cells function normally in the body, they produce damaged molecules called free radicals. These free radicals are highly unstable and steal components from other cellular molecules, such as fat, protein or DNA, thereby spreading the damage.
This damage continues in a chain reaction, and entire cells soon become damaged and die in a process called peroxidation. Peroxidation is useful because it helps the body destroy cells that have outlived their usefulness and kills germs and parasites. However, when left unchecked, peroxidation also destroys or damages healthy cells.
Antioxidants help prevent widespread cellular destruction by willingly donating components to stabilize free radicals. More importantly, antioxidants return to the surface of the cell to stabilize rather than damage other cellular components.
When there are not enough antioxidants to hold peroxidation in check, free radicals begin damaging healthy cells, which can lead to problems. For example, free radical damage to immune cells can lead to an increased risk of infection.
Because antioxidants play a key role in minimizing damage to cells, such as those that make up the immune system, recent research examined the benefits of certain antioxidants on the immune response of cats. The results of these studies indicated that antioxidants are important in helping cats maintain a healthy immune system.
The research also showed that each antioxidant benefits the immune system uniquely, so one antioxidant at high levels is not as effective as a group of antioxidants acting together.
Antioxidant | Source | Function |
Vitamin E | Plant oil extract, tocopherols | Optimizes immune system’s T-cell activation |
Beta-carotene | Vitamin premix, corn meal, chicken by-product meal and chicken fat | Optimizes types of cells present in the blood, increases antibody levels in the blood and optimizes vaccine recognition |
Recent research also examined the effect of aging on immune responses. The findings indicate that as cats age, immune cell responses may decline. Including antioxidants in your cat’s diet can help reverse the age-related decrease in immune cell function, returning it to healthy adult levels.
