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.


UTI, also known as Urinary Tract Infections, are any infection in the urinary system. Such infections are not common in cats. In fact, not every cat with UTI symptoms has a urinary tract infection. According to NCBI, only one to two percent of cats suffer from urinary tract infections. However, UTIs resemble several other feline diseases; hence, it is imperative to visit a vet for further diagnosis.
Since Urinary Tract Infections can cause severe pain and discomfort, every cat parent must learn about cat UTI symptoms. Here are a few major UTI symptoms in cats:
Blood in the urine
Constant licking of the urinary opening
Crying out while passing urine
Urinating outside the litter box
In order to diagnose UTI in cats, veterinarians first test urine samples. This test helps them detect any bacteria in the urine. Doctors directly draw urine from the bladder with a needle to avoid contamination. Once the urine sample is tested, the vet will then isolate the bacteria to study it further. This step is called the Culture and Sensitivity test. It helps determine the right medicines based on the cat's infection.
First-time infections or acute infections are generally cured using broad-spectrum antibiotics. However, if your cat is suffering from a chronic infection, the vet might recommend additional tests to start bacteria-specific medication.
There are multiple factors that can lead to UTI in cats. Let's explore a few common causes of cat UTI:
Replacement of the urinary catheter
Bladder stone
Issues with the cat's gastrointestinal tract
Although UTI is rare in cats, it's best to take the right measures to prevent it at all costs. Here are a few points on how to prevent UTI in cats:
There are multiple cat UTI home remedies like cranberry juice, apple cider vinegar, bone broth, etc. And most of them are believed to alleviate the symptoms of UTI. However, we do not know if these remedies heal you completely. Hence, it is best to consult a veterinary doctor for cat UTIs. Moreover, in some cases, especially if left untreated, UTIs can be recurrent. The vet will provide the right medication to get rid of the bacteria.
