Much like the human gut, your cat’s gut is responsible for warding off foreign organisms and absorbing nutrients. This important function is made possible by little, tiny bacteria who make their home there.

In order to ensure that your cat remains as healthy as possible, along with a well-balanced meal, you should be providing it with supplements called probiotics that help these good bacteria to thrive. Doing so can make a huge difference in your cat’s mood and overall well-being.

To save your time, we have tirelessly researched countless cat probiotics in order to bring you the top products on the market. We also want to answer all of your questions to give you more information about what they are and how they benefit your cat.

What Are Probiotics?

According to 4ahealthygut, probiotics are good bacteria that are either the same or similar to the ones that live in the body. Their job is to fight against bad bacteria and other foreign microbes that enter the body.

Stress, problems with food, and illnesses can weaken your cat’s ability to fight these bad bacteria. Probiotics can help them maintain their health during this time of weakness by keeping a constant flow of bacteria into their gut which will replenish their system helping them to recover faster.

Check out this YouTube video by Chewy University on What Probiotics are and why they are important for your cat.

Things To Look for In Probiotic Supplements

In order to choose the best probiotic for your cat, Dr. Patrick Mahaney with PetMD, recommends looking for at least two different types of bacteria from the families Bifidobacterium and Enterococcus.

In other words, if a probiotic has only two bacteria from the Bifidobacterium family, you should not go with it. That’s because both types of bacteria live in different parts of your cat’s gut.

Bifidobacterium lives in your cat’s small intestines while Enterococcus lives in the colon/large intestines. Mahaney recommends, however, that you should look for probiotics with up to 5 different types of bacteria and go for the one with the highest CFU (colony forming units).

You also want to look at the ingredients and choose a product that is free of fillers like grains and sugars. The product should also contain good ingredients that are responsibly sourced.

Products that are USDA Certified Organic, non-GMO, soy free, etc. are a good indication that the probiotic contains good ingredients.

The product should not have to be refrigerated because the drying process freezes the bacteria until they are reactivated in your cat’s gut.

Why Are Probiotics Important for Cats?

Probiotics are important to aid your cat in maintaining healthy gut health and also a good immune system.

They help your cat avoid a slew of digestive issues including, but not limited to, diarrhea, gas, vomiting, bloating, constipation, and more!

In addition, as Food Fur Life reports, probiotics help your cat to stay healthy since a large portion of its immune system is located in the gut.

When you give your cat probiotics you will notice reduced instances of diarrhea and other digestive issues but also an improvement in its skin, coat, and even overall mood.

Do Cats Need Probiotics?

The answer to this question ultimately depends on you. Does your cat’s health matter to you?

We hope your answer to this question is yes because your cat’s health is important. That being said, we do highly recommend that you incorporate a good probiotic into your cat’s diet.

Benefits of Probiotics for Cats

Cummings School of Veterinary Medicine at Tufts University suggests that there are many benefits to giving your cat probiotics.

It will drastically increase the number of bacteria in your cat’s intestines. When this happens, your cat will experience an improvement in digestive conditions as well as a better immune system.

To put it into perspective, Cummings School of Veterinary Medicine reports on a study surrounding kittens that suffered from acute diarrhea. Of the kittens who were given a probiotic, only 9.5% of the group needed further treatment.

On the other hand, 60% of kittens needed additional treatment who did not receive any probiotics.

From this study alone-, you can see the real benefit that probiotics can have on your cat or kitten’s health. You can also take note that these kittens were already sick before they were given probiotics.

When you are consistent with giving them to your cat, it will have an even better chance of fighting off ailments and living a healthy lifestyle because its gut will already be fortified with large colonies of good bacteria.

Another benefit that your cat will experience when taking a probiotic regularly is increased efficiency in nutrient absorption. This means that your cat will get the best out of the food it is eating and will likely eat less food in a day.

This will not only help your cat become more healthy but it will help you save a lot of money on cat food and cat litter since it will also be pooping less too.

And speaking of poop. When your cat has good gut health, its pee and poo will stink less meaning you will not have to worry about masking offensive odors that can creep about your house after your cat does its business.

Possible Side Effects and Risks of Giving Your Cat Probiotics

There are no known side effects to giving your cat probiotics. They also suggest that because there will be a large increase in activity within your cat’s gut, you might notice it becomes gassier or passes solids in the litter box more or less often than usual.

These effects are normal and should subside in a few days. Be sure that you are using products that are free of fillers and other bad ingredients that will cause irritation throughout your cat’s digestive system.

If your cat’s condition does not get better within a few days, stop giving it the product and consult your vet for further instructions.

What Is The Difference Between Multi-Vitamins and Probiotics?

Although they are both important components of your cat’s well-being, probiotics and multivitamins are not the same. As Probiotics for cats explains, multivitamins provide nutrition to your cat’s entire body.

On the other hand, probiotics provide support to your cat’s gut. The irony of this relationship is that your cat’s body will not be able to absorb the nutrients delivered by the multivitamin if it does not have a healthy colony of bacteria in its gut.

Now that you see why giving your cat a daily dose of the probiotic supplement daily is so important it’s time to act now. Do not click away from this and leave it to chance that you will get to it ‘someday’.
