Does My Cat Really Need Probiotics?

Probiotics contain good bacteria that can improve the cat’s digestive system and improve their health in general. Typically, probiotic is helpful in tackling diseases like the gastrointestinal tract, loose stools, vomiting, diarrhea, or inflammatory bowel disease (IBD). Aside from these medical conditions, probiotics can help the cat in stressful situations because it works on maintaining the immune system of a cat. Furthermore, it is helpful to use probiotics when a cat is given antibiotics. The antibiotics also decrease the good bacteria, due to which, giving probiotics can help maintain a balance of good bacteria. As it maintains the gut system, the probiotics can help a cat switch from dry food to wet food. Probiotics can also be good for skin allergies if it contains fatty acids.

Can I Give Them Human Probiotics?

Some people often ask me if it is okay to give their cat a human probiotic, the quick answer is a big no. There is just no scientific evidence to support the claim that human probiotics help the cat. The human probiotics contain doses that are made for humans. In contrast, your cat won’t require that large amount of dosage which is meant for humans. Additionally, the good bacteria humans require, Bifidobacteria is not the same good bacteria your cat needs, Lactobacillus. While you’re here, I might as well tell you that it is not okay to give your cat a dog probiotic. The exception being probiotics which are made for both, cats and dogs.

Are There Any Side-effects To Probiotics?

It is only natural for a pet parent to wonder if a new medication will affect their cat. Rest assured, probiotics rarely have any side-effects. This doesn’t mean there are not any probiotics that could harm your cat.

Hence it is necessary to check the following things when getting probiotics for your cat;

  • NASC quality seal
  • Advice from the vet
  • Purchasing from reputed companies like Purina

The extent of side effects is diarrhea and vomiting. This would occur in instances where the cat can’t handle the good bacteria or other ingredients in the probiotic you are using.

Things To Consider When Purchasing A Probiotic Supplement

In the previous section, I talked about how side effects are a result of a poor quality probiotic. So, this portion of the article is dedicated to helping you identify the right probiotic of good quality. Without any further delay, let’s dive right into it; you need to consider the strains, ingredients, and expiry date (duh!).

Strains

First off, you will need to find the probiotic where your cat can get live microorganisms. Why? A live strain of microorganism will help your cat maintain its digestive tract.

Then, you have strains of pure or artificially modified bacteria and yeast. I would urge you to find the ones that offer pure bacteria and strain, that do not contain any artificial additives because they could be dangerous for the cat’s health in the long term.

Artificial Ingredients

Speaking of additives, there are probiotics with artificial ingredients that could affect cats with the sensitive digestive system. So, you should look for probiotics made with natural ingredients. There are ingredients with artificial flavorings, colors, and some preservatives which could have an adverse effect on your cat’s immune system or digestive system.

Expiry Date

There are two kinds of people, those that check the expiry date before purchasing a product, and there are people who check the expiry date when things get worse. Don’t be the second kind, you should know better than to purchase a product beyond its expiry date. There are some instances where you might receive a probiotic beyond the expiry date, for which I would recommend seeking out the manufacturer for a refund or a replacement.

Bonus: Wet Food

Additionally, I would recommend finding the probiotic that can be easily mixed with wet food. This will make it easier for the cat to eat up the probiotic with the food. Compared to dry food, it is hard to notice anything added to wet food.

Know Your Probiotics

There are three types of probiotics that your cat should be given;

  1. Bifidobacterium
  2. Enterococcus
  3. Lactobacillus

Bifidobacterium is a strain of probiotics that provides the cat’s small intestines the necessary good bacteria. If your cat has digestive problems, look for probiotics that with the Bifidobacterium. The second probiotic is a strain that provides large intestine bacteria to the cat. It is helpful in normalizing the stool of a cat. Lastly, Lactobacillus is found in the most dietary supplements and dairy products. It helps improve the health of a cat’s digestive and urinary systems.

The Probiotics Isn’t Working On My Cat

Probiotics take time to work on your cat, don’t worry it has been a day or two, and there is no effect on your cat. The probiotics will take a couple of weeks when it has an effect. At that point, when you don’t see any changes, you can presume it is not effective for the cat.

In case your cat is just not eating the probiotic initially, I would advise steadily introducing it in the cat’s diet. You can do this by starting off by mixing about half a dose of probiotics. Over time, you can steadily increase the dosage when the cat gets accustomed.
