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.
Your adult cat is a perfect specimen of mobility, speed, acuity, and grace. She is in her prime. She shines in her gleaming coat and her eyes are bright.
Jumping, twisting, and landing, her skeleton bears strain our own bodies could never endure. Her muscles are highly flexible. Her movements are lightning fast and her senses highly tuned.
Between ages 1 and 8, your cat will experience the equivalent of a human's journey from teenager to late middle age. As caretaker, you are responsible for good adult cat health and lifestyle in these years and beyond.
It can be difficult to keep such an adventurous creature indoors. But to do so is proven to extend a cat's life, because it limits exposure to predators, cars, fleas, and other cats that may have diseases such as feline leukemia or feline immunodeficiency virus (FIV). Keep your cat duly entertained indoors by providing toys, structures to climb on, spots near windows to watch the action outdoors, or–if she responds to them–TV and special videos.
One potential side effect of being a pampered, indoor cat is obesity. If your cat starts to gain weight, limit or change her diet and encourage more exercise. Make time for play with your cat each day.
An adult cat should visit the vet annually. Dental and gum disease, diabetes, hyperthyroidism, and other medical problems can present themselves in adulthood to middle age. Early detection is essential to successful treatment and extended life.
As your cat nears 8 years old, be sure to watch for signs of other age-related illnesses such as weight loss, decreased appetite, neglect of grooming, increased thirst and urination, and retreating from the household.
Both you and your cat will enjoy these peak years. They will be filled with acrobatic antics and lithe poses you can't help photographing. If you take the appropriate precautions, you can extend the health and fun for many years.
