Who Should Buy Probiotics for Cats

A probiotic for cats is an ideal choice for those whose feline companions are experiencing symptoms of digestive upset, including nausea, gas, vomiting, diarrhea, loose stools, and weight loss. If your kitty has especially stinky poops, probiotics may also be indicated and helpful.

Probiotics are also recommended by veterinarians for cats who suffer from seasonal allergies or skin conditions, as research has shown them to be effective in the treatment of these conditions. Finally, a probiotic can also be used as an addition to a well-balanced diet for even healthy cats in order to help promote and maintain overall health and wellness.

It is important to note that cats have a different gut flora than humans and dogs, which means that it is important to feed your feline a probiotic that has been specifically formulated for their species. This way, your furry friend will get the most benefit from your investment in this supplement.

Always speak to your cat’s veterinarian before giving your cat probiotics or other supplements, to ensure it’s the right product and dosage for them.

Important Features to Consider

Not all probiotics for cats are created equal. A probiotic for cats should be easy to administer and made with safe ingredients. Here’s what to consider when evaluating the options in search of the best probiotics for cats:

  • Type. Arguably the most important consideration when it comes to choosing the best probiotic for cats is the type or form it comes in. Cat probiotics come in a variety of forms including gels, powders, pills, and infused treats. If your cat won’t swallow a capsule, you can try hiding it inside of a treat, or simply use a product that can be sprinkled on your cat’s food or mixed in their water.
  • Strain. The next most important consideration when it comes to shopping for probiotics for cats is the strains in the supplement. While you probably won’t harm your cat by given them human probiotics, it is recommended to give them a formula that has been specifically made for felines. Strains from the Bifidobacterium and Enterococcus families tend to work best for felines, and diversity is just as important in cats as it is in humans.
  • CFUs. You want to find the probiotic with the highest  CFU (colony forming units) that you can find. A minimum of 10 million CFUs is a good starting point, but if you can find a supplement with CFUs in the billions, that is even more beneficial.
  • NASC quality seal. The National Animal Supplement Council is a nonprofit industry group that evaluates pet products for compliance with rigorous quality system requirements. This seal indicates that a product comes from a reputable company that has successfully passed an independent quality audit.
  • Price point. Finally, consider how much you are willing to spend on a probiotic for cats. Probiotics for cats vary in price from $10-$50 or more.

Frequently Asked Questions

What are probiotics for cats and how do they work?

Probiotics for cats are microorganisms that live in the digestive tract and help to improve digestive and immune health.

How long does it take for probiotics to work in cats?

Some pet owners may notice minor improvements in their feline’s health within a couple of days of use, however, most pet owners can expect probiotics to take at least a couple of weeks to start working in their cat.
