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.
Providing your kitten with the proper nutrition goes way beyond just putting fresh food in a clean bowl. Your kitten’s nutritional needs will change as her body develops through adolescence. Proper nutrition during these critical growth periods will help your kitten mature into a strong, healthy adult cat. Discover four essential kitten-feeding tips you need to know in your kitten’s first year.
Learning what development milestones your kitten will experience in her first year will help you decide what and when to feed her.
After kittens are weaned, they enter a stage of rapid growth, which lasts through the sixth month of life. They need a balanced diet to deliver the nutrients and energy to sustain such rapid development.
Kittens have twice the energy needs of adult cats on a pound-per-pound basis. But their smaller mouths, teeth and stomachs limit the amount of food they can digest during a single meal. Therefore, it may be best to divide their total daily food amount into three or four smaller meals.
Because every bite must be packed with nutrition, kittens require a diet specifically formulated for growth. The best choice is a food with animal-based proteins that is highly digestible, nutrient dense and designed to meet kittens’ unique nutritional needs.
As kittens approach adult size, their nutritional requirements begin to change again. Their rate of growth begins to slow, activity levels may decline and they can start eating fewer, larger meals each day. During this stage, kittens begin to look like adults, but they are still growing and need the special nutrition found in kitten food.
The adolescent growth stage is a time when many cat owners are tempted to change a kitten’s food for variety. But cats do not get bored with a consistent diet of high-quality dry food. You can supplement your kitten’s dry food with a nutrient-dense canned food for a nutritious change of pace.
When your cat is about 12 months old, it’s time to switch to a maintenance formula adult cat food, such as IAMS™ ProActive Health™ Healthy Adult with Chicken. At this age, cats no longer need the extra calories and nutrients for growth supplied by kitten food. As with any change in a cat’s diet, remember to gradually transition from kitten food to adult food over a period of several days.
Monitor your cat’s weight and body condition during the transition, and adjust feeding portions if necessary. Because cats generally eat only what they need, free-choice feeding is fine for most cats. However, some indoor cats that don’t exercise much may overeat if fed free choice. In this situation, portion-controlled feeding twice a day is a good alternative.
Giving a kitten “human food” and table scraps can lead to undesirable behaviors, such as begging or stealing food. Feeding homemade diets or food formulated for adult cats (especially those designed for weight loss), or supplementing a complete and balanced diet with vitamins could cause nutritional disorders.
Kittens and cats are strict carnivores and need the nutrients found in meat. For example, sufficient amounts of taurine, an essential amino acid provided naturally through meat, help cats maintain healthy eyes, heart and reproduction. All IAMS kitten and cat food formulas have optimal levels of taurine for every life stage.
