What is the Difference Between Prebiotics and Probiotics for Cats?

Prebiotics are non-digestible carbohydrates offering nutrients that selectively support the good bacteria in the gastrointestinal tract. From a chemical standpoint, they are sugars, but nutritionally speaking, they lack sugar-associated calories. The most common types are fructooligosaccharides (FOS), inulin, and oligosaccharides.  

Probiotics are naturally occurring live microorganisms that inhabit the gut. The purpose of the intestinal microorganisms is to digest food, support the layers of the intestines to remain healthy, and help with metabolism in the cat

Simply put, prebiotics (dietary fiber) serve as food for the probiotics (good bacteria).

Are Prebiotics Safe for Cats?

Yes, prebiotics are safe for cats. That said, the best sources of prebiotics are the products that have scientific studies behind them. Prebiotics doses have not been well determined, and every cat owner must be aware that high doses can cause diarrhea or changes in the frequency of bowel movements. 

Another way to include prebiotics and probiotics is to use diets that include them. The fiber sources used should be listed in the ingredients and should say whether it is a source of FOS or inulin. 

When used in adequate amounts and in accordance with the manufacturer’s guidelines and a veterinarian’s approval, probiotics are perfectly safe. Prebiotics offer several health benefits for pets – from a healthy GI tract to improved immune system function. 

Dr. Teri Byrd says, “In veterinary medicine, one of the most important things we can do in today’s world is to use natural substances to promote health and well-being in our animal patients. Prebiotics and probiotics are great examples of natural substances that we can use to help animals with gastrointestinal distress, antibiotic therapy, and with stress.”

What are the Benefits of Prebiotics for Cats?

Prebiotics for cats support a healthy gut microbiome which affects stool quality, digestion, and immunity. Here is a closer look at the benefits of prebiotics for cats.

  • Gut Microbiome: The gut microflora is easily affected and thrown out of balance by sudden diet changes, dietary indiscretions, prolonged use of certain meds (antibiotics), and intestinal parasites. In such cases, the use of pre+probiotics will help restore balance and ensure normal gastrointestinal function and overall health.  
  • Stool Quality: Just like kittens and cats have sensitive stomachs and often suffer from diarrhea and constipation. In both cases, nutrient absorption is compromised, leading to long-term issues. The use of pre+probiotics can improve stool consistency and can promote normal fecal formation.  
  • Chronic GI Diseases: Common chronic GI tract ailments in cats include inflammatory bowel disease (IBD), food sensitivities, and allergies. Supplementing your cat with pre+probiotics will provide relief from inflammation and ease the associated symptoms. 
  • Healthy Body Weight: Obesity is a common problem in modern cats, and increases the risk of diabetes which is also widespread. Prebiotics can help with obesity by promoting normal body weight, modulating glucose metabolism, and increasing insulin sensitivity
  • Immune System Boost: The intestinal wall is an important pathogen barrier, and a large portion of the immune system is located in the gut. Therefore, there is a close link between a healthy gut and a strong immune response. Using pre+probiotics is critical for a balanced gut and robust immunity

What Should I Look for in Prebiotics for Cats?

When shopping for prebiotics for cats, there are several things to consider:

  • Prebiotic Type: First of all, you need to pay attention to the type of prebiotic in the product and the amount per dose.
  • Active Ingredients: Many prebiotic supplements feature added ingredients such as species-specific cat probiotics and digestive enzymes. If you are not sure which active ingredients would be helpful to your cat, talk to the vet.
  • Form & Flavor: Prebiotic cat supplements come in different forms (chews, powders, liquids) and flavors (bacon, chicken, salmon). Choose the combo that suits you and your cat best.
  • Brand: Consider the brand you are purchasing. Always read reviews from other customers and pay attention to factors such as money-back or satisfaction guarantees. Also, a reliable brand will be open and transparent.

Why are Prebiotics Added to Cat Food?

Prebiotics for cats is added to pet food to utilize their health benefits. For example:

  • Support Beneficial Bacteria: As explained, prebiotics nurtures the good bacteria in the gut, thus promoting balance and a healthy environment.
  • Healthy Digestive Tract: A balanced gut means healthy digestion – nutrient absorption and utilization. This prevents digestion issues like diarrhea and constipation.
  • Strong Immunity: There is a strong connection between a healthy gut and potent immunity. Prebiotics strengthen immune responses and reduce the risk of infectious diseases.

Can Prebiotics Cause Diarrhea in Cats?

Yes, prebiotics for cats can sometimes cause diarrhea and loose stool in cats and a change in the frequency of defecation. 

Giving your cat too many prebiotics may result in stomach upset, and issues such as loose stool, diarrhea, and constipation. However, these side effects are mild and transient.

Since doses have not been well established in prebiotics, one recommendation is to start low doses and increase up “to effect.” A consistent dose for each meal is a good idea. Start low – no more than 1/8 – 1/4 tsp per meal in the beginning.

How Often Should You Give a Cat Prebiotics?

Usually, cats are supplemented with prebiotics when dealing with certain conditions – such as antibiotic therapy, before surgery, when stressed- car rides, moving to a new home, viral illnesses, etc. However, many vets recommend making prebiotics a daily supplement.

According to Animal Wellness Magazine, “Prebiotics for cats can be used on a regular basis as part of your pet’s wellness routine.“

How Long Does it Take for Prebiotics to Work in Cats?

Prebiotics in cats starts working as soon as they reach the intestines.

However, to see an improvement in your cat’s health, you will have to wait for the probiotics to start working, which can vary from several days in cases of managing diarrhea to several weeks in cases of boosting immune system issues.
