Four of Our Best Tips in Selecting the Best Probiotics for Cats

Probiotics are part and parcel of every cat’s life. They not only help in eliminating harmful bacteria but also improve health. But, many pet owners face the challenge of selecting the right probiotic.

If you are among them, here are the best tips to guide you when choosing a safe probiotic for your cat or dog.

Select a human-grade probiotic rather than a veterinary probiotic

Topping the list is selecting the right probiotic for your cat. These supplements are available in two kinds, human-grade, and veterinary probiotics.

A human-grade supplement is much better because it is regulated. Moreover, the constituents in the bottle have to march with what is on the label. On the flip side, Veterinary probiotics don’t have strict measures.

Most of the products’ constituents are not what is on the label. You might also find them having half of what is on the label, while some don’t contain the live bacteria.

Look for several different bacterial strains on the ingredient list

Another essential tip to consider is the variety of strains on the ingredient list. Ingredient list plays a vital role in the health of live beings. Apart from being anti-inflammatory and anti-aging, it might be an anti-cancer. Besides that, several strains of bacteria will help your car in reducing infections.

Choose a probiotic that is in an enteric-coated capsule

An enteric-coated capsule plays a vital role in the health system. So, it provides the medication given to your cat or dog. It also prevents probiotics from being digested by stomach acid.

Consider a different approach if your pet suffers from chronic digestive issues

As mentioned earlier, probiotics are safe for your cat and dogs. But, they are not suitable for all types of pets but only those with digestive issues. They are well balanced and contain fewer microbes.
