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.
Knowing your cat needs a change in their diet is one thing, but knowing how to make that change is something else! Cats are creatures of habit, so it’s not uncommon for them to prefer their current food to anything new. Change disrupts their routine, which can impact their behavior and their digestion.
Thankfully, when the time has come to change your cat’s diet, a little planning and preparation goes a long way toward making the transition easier for them (and for you).
The following tips will help you change your cat’s diet and successfully transition your cat to a new food:
There are lots of reasons to consider changing your cat’s food — maybe you have a new kitten to wean, a kitten who’s all grown up now or an adult cat entering their senior years. In addition to normal aging, advice from the vet is a common reason to change what you’re feeding your cat. Cats that need help reducing their weight or managing excessive hairballs might need the support of a new food designed with those needs in mind. Whatever your reason for changing your cat’s diet, make sure the new food will suit their needs. That way you only have to make the transition once, and can avoid upsetting their stomach by changing the routine too often.
Going slow is paws down the most successful way to ease your cat into a different diet. Start by mixing 25% new food with 75% familiar food. Slowly change the proportions over the next three days or so by gradually increasing the amount of new food and decreasing the amount of their familiar food. Think of it as a kind of weaning — at the end of this process, you should be feeding (and your cat should be eating) just the new food.
Your cat may choose to eat only the familiar food, or not eat at all … at first. But a healthy cat can miss meals for a day or two without causing health problems. Slow, steady and consistent wins this race!
How would you feel if someone tried to force you to eat strange food you didn’t want?
Aggressively dumping the new food into your cat’s dish and declaring that your cat had better eat it might inspire your cat to do anything besides eat!
A little gentleness in your approach goes a long way. Try using a pleasant tone of voice and encouraging your cat to taste the new food. Even if they don’t go for it at first, a gentle approach still goes over much better than an aggressive one.
Cats train us as much as we train them. Giving in to their demands reinforces that their refusal to eat the new food is acceptable, which makes transitioning to the new diet even more challenging in the long run.
So don’t give up! Don’t be tempted to revert back to your cat’s familiar foods, and don’t give your cat treats or table scraps during the initial three-day period.
This is the toughest dietary transition of them all, but there are a few ways to make the process easier. If your cat resists eating dry food for more than a few meals, try mixing a little warm water with it and maybe even warming the moistened food in the microwave for a few seconds.
If you mix dry food with water, remember to discard any uneaten leftovers after 20 minutes to prevent spoilage. (The same rule applies for wet food.) After your cat is used to the moistened dry food, you can gradually transition to serving the same food dry.
Changing your cat’s diet is sometimes necessary to help them live a happy, healthy life. The process of switching what, how or how often you feed your cat can be a little bumpy, but you can do it! By going slowly, staying patient and encouraging, sticking to the plan and making the transition as easy as possible, you’ll be giving your cat what they need and helping them adjust as comfortably as possible.
