【Written by a Veterinarian】Do Cats Need Probiotics or Lactic Acid Bacteria? Gut Health for Longevity and Precautions for Administration

"Is it safe to give cats intestinal regulators?" "Can probiotics improve gut health?"—these are questions that health-conscious cat owners have likely considered. Improving the intestinal environment can help with everything from everyday stomach issues like constipation and diarrhea to skin diseases. In this article, a veterinarian explains intestinal regulators, probiotics, and gut health management.

Are intestinal regulators necessary for cats?

The role of intestinal regulators

Intestinal regulators work to improve stomach conditions and stop diarrhea. They primarily contain lactic acid bacteria, which travel to the intestines to support the function of beneficial bacteria. In addition to lactic acid bacteria, they may contain ingredients like digestive enzymes to assist with digestion and absorption.

Cases where they are prescribed for constipation or diarrhea

Intestinal regulators are mainly prescribed for symptoms such as diarrhea and constipation. Because they support the activity of beneficial gut bacteria, they can be expected to improve the condition of a cat's stool.

Intestinal regulators for animals

There are intestinal regulators for humans and those for animals. Most products handled by veterinary clinics are classified as veterinary drugs. Beyond lactic acid bacteria, these drugs contain other ingredients, and in the case of veterinary medications, the dosage is adjusted specifically for animals. On the other hand, human intestinal regulators are made with adults in mind, meaning they differ in terms of body weight and metabolic pathways. Some owners try to calculate a dose by splitting human medication based on weight, but this can sometimes have adverse effects on cats.Avoid giving human intestinal regulators based on your own judgment.

Benefits of giving cats probiotics

Regulating the intestinal environment and improving bowel movements

The intestines contain countless bacteria known as gut microbiota, which are categorized into beneficial bacteria, harmful bacteria, and opportunistic bacteria. Collectively, this is called the gut flora. When a cat has an upset stomach, harmful bacteria have become dominant. When lactic acid bacteria reach the intestines, they produce substances like lactic acid and acetic acid, creating an environment where harmful bacteria have difficulty multiplying. Once the intestinal environment is balanced, the intestinal barrier is maintained, inflammation is suppressed, and bowel movements improve.

Supporting the immune system and contributing to infection prevention

Because the intestines are home to countless bacteria, lymphoid tissues called Peyer's patches exist in the intestinal tract to prevent these bacteria from entering the body. Lactic acid bacteria are known to activate immune cells, which is why probiotic drinks that support the immune system are sold for humans as well. Consuming lactic acid bacteria regularly is thought to activate the immune system and help prevent infectious diseases.

Maintaining health in senior cats and those with underlying conditions

Because lactic acid bacteria regulate the intestinal environment, they inhibit the growth of harmful bacteria. In humans, it has been reported that harmful gut bacteria produce carcinogens, increasing the risk of colon and esophageal cancer. While this is not yet confirmed in cats, a balanced intestinal environment and a stimulated immune system may help suppress cancer.

In veterinary medicine, the effects of lactic acid bacteria are garnering attention, and various supplements are being developed. Lactic acid bacteria are showing promise for cats with chronic kidney disease (CKD). Uremic toxins produced in the intestines are metabolized in the liver and then excreted by the kidneys. In advanced CKD, the kidneys fail to excrete these toxins, leading to accumulation in the body and "uremia." The mechanism involves lactic acid bacteria breaking down these uremic toxins in the gut, making them less likely to accumulate in the body. This may help alleviate symptoms such as loss of appetite and vomiting during the uremic phase.

Additionally, some lactic acid bacteria are known to activate lymphocytes that suppress overactive immune responses, which is thought to potentially reduce symptoms of atopic dermatitis and allergic dermatitis.

Methods and precautions for cat gut health management

Make good use of intestinal regulators, probiotic supplements, and therapeutic diets

Intestinal regulators and probiotic supplements are intended solely for improving the intestinal environment. Since lactic acid bacteria do not permanently colonize the gut, they are most effective when taken consistently. Some therapeutic diets also contain lactic acid bacteria, so it is best to incorporate them in a way that is easy to maintain.

Increasing effectiveness with prebiotics

Gut health management involves two concepts: prebiotics and probiotics. Simply put, prebiotics are the food that activates beneficial bacteria in the gut, while probiotics are the beneficial bacteria themselves. Examples of food for beneficial bacteria include oligosaccharides and dietary fiber. Even if you introduce beneficial bacteria like lactic acid bacteria through supplements, they will not activate without their "fuel." It is important to incorporate prebiotics alongside them.

Precautions regarding side effects and compatibility

Intestinal regulators may contain ingredients other than lactic acid bacteria. Supplements can also contain various ingredients that might not agree with your cat's constitution. If you notice any abnormalities after starting a new product, stop immediately and consult your veterinarian. Always choose products designed for cats or animals.

Daily gut health care

Promoting intestinal peristalsis with moderate exercise

When cats lack exercise, their metabolism may slow down, and digestive function can decrease. Additionally, stress from lack of exercise can lead to a weakened immune system. While excessive exercise is counterproductive, moderate activity helps maintain proper digestive function.

Stress care is directly linked to an improved intestinal environment

When a cat is stressed, immune cell activation drops, leading to weakened immunity. The same applies to the intestines; stress causes the intestinal environment to become dominated by harmful bacteria. It is important to provide moderate exercise and create a safe environment where your cat can spend time without worry to help alleviate stress.

Conclusion | Protecting your cat's health through gut management

Countless bacteria exist in the intestines, and it is known that activating beneficial bacteria boosts immune function. Gut health management using probiotics like lactic acid bacteria is garnering attention as a way to improve the intestinal environment. Lactic acid bacteria preparations should be taken regularly, so choose a format—such as supplements or food—that is easy to continue. Since some gut health products may not suit your cat’s specific constitution, stop immediately if you notice any abnormalities and consult a veterinarian.
