Buying Guide

If you are looking to help your cat with digestion issues, reduce shedding, improve their immune system, or get rid of hot spots, a probiotic is the way to go. A probiotic helps to promote healthy bacteria in your cat’s gut which can do a lot for their overall health. Before you select which probiotic you’d like to try with your cat, take a few moments to compare your options and make sure you make the best selection for your cat.

Product Type

First, you should consider which type of probiotic you would like to give your cat. Some options include a tasteless powder that you can sprinkle over their food, a soft-chew treat, or a flavored powder to entice your cat to eat it.

The probiotic you choose typically won’t affect how it works. You should think about your cat and their preferences before you make a decision.


This is related to the last section, but you should also consider the taste of the different products. If your cat is on the picker side and you think may refuse a flavored packet or treat, then you may want to consider a tasteless powder. On the other hand, if your cat is more motivated by new tastes and flavors, using a treat or flavored pouch might be the way to go.

Probiotic Strands

There will likely be numerous probiotic strands included in any of the products out there. It is important to look for those that include live strands, since these will make it more likely that your cat will experience the health benefits you’re looking for.

If possible, try to look for strains from one of the following families, since they have been shown to be effective for helping cats:

  • Bifidobacterium bifidum: helps with digestion.
  • Enterococcus: helps your cat’s colon produce regular feces.

CFU Count

The CFU count, or the colony forming units count, is another important thing to look for when you are comparing different probiotics. The CFU count refers to the number of live microorganisms in every serving of the probiotic.

You want to find a product that has a very high CFU count for best results. Look for a number in the billions when possible.


You should pay attention to the formulation of the product. Was it designed specifically for cats, or can it be used by dogs too? Selecting an option that is designed exclusively for cats will make it more likely that all the bacteria strains are more effective for cats.

You should also look to see if there are any added ingredients that shouldn’t be in the probiotic. Try to avoid options that include fillers, preservatives, artificial flavors, or artificial colors.

Manufacturing Information

Finally, consider any information that is provided about the manufacturing process. Look for products that are made in The United States.

You can also look for a product with the NASC seal. NASC stands for National Animal Supplement Council, and selecting a product with their seal means that it has met more rigorous requirements.
