Cat probiotics are a new healthy trend in feline nutrition. The truth is, probiotics are great for cat digestive health and maintaining wellness, but not all products are equally beneficial for them. On top of that, there are products and cat foods coming out all the time online, and at PetSmart, that supposedly include probiotics. Can we trust them? With so much convoluted information, we wanted to know which products are really good for our kitties, which products were feline-appropriate (biologically appropriate for cats), and which probiotics will truly fortify excellent cat health.

Problem #1:Low Efficacy
Cat foods and treats with probiotics added have been found to have far less, if any, actual viable bacteria.

Problem #2: Not Biologically Appropriate for Cats
Most probiotic supplements for cats are actually human supplements with a cat-friendly label attached. A cat's digestive system is much different from that of a human, so giving your cat the wrong kind of probiotic could be a big mistake, or at the very least, a big waste of money. (We'll give you a couple tips on how to identify a human-intended probiotic below)

The Best Probiotics Help With:

  • Yeast infections
  • Obesity
  • Skin rashes, dermatitis
  • Urogenital tract infections
  • Irregular bowel function (diarrhea, loose stool, or constipation)
  • Excessive shedding
  • Production of natural digestive enzymes
  • Production of B vitamins

5 Things to Look for in the Right Product

1. Choose dry powder probiotic supplements.

Powders are the most stable form of healthy bacteria. They are more desirable than liquids, tablets, pastes, or treats. More natural probiotics can be contained in a tiny scoop of powder than in any other supplement form, and, because it's in a dry, suspended state, the viable microorganisms can live for over a year if stored in the right conditions.

2. Not too many species (strains) of bacteria, please!

Keep in mind that bacteria is alive. When attached to the intestine, these living microorganisms compete with eachother to dominate the GI tract, and, some species live together more harmoniously than others.

Also, its important to know that only a few species have been studied to be helpful for feline health, so choosing a probiotic with 6 species or less is a wise choice and will likely be more feline-appropriate. This ensures that the valuable species are not diluted by the speculative ones. Loading your cat up with a super-complex probiotic formula could cause feline GI upset, or at the very least, be a total waste of money.

3. Look for prebiotics in the formula

There are all kinds of materials used as "prebiotics", such as, FOS, inulin fiber, or acacia gum, but essentially, their purpose is to enhance the activity of natural probiotics, giving them food to eat and multiply. Prebiotics are an absolute must for any probiotic supplement, but especially for obligate carnivores, like cats.

4. Don't super-load the CFU!

Its easy to see that pet probiotics with dosages are all over the map. You can find products that offer 100 million all the way to 60 billion CFU per dose. Wow! If you see a "cat probiotic" with a CFU/dose anywhere above 10+ Billion per dose, you can bet it's a human — NOT feline-appropriate. So what's the right dosage?

Remember that your cat is tiny, and has a very efficient digestive tract. Our findings are that around 500 million CFU is per day is perfect for maintaining wellness in cats. If recovering from antibiotics or illness, your cat could use 2-4 times that amount. It's true that it's hard to overdo it with dosage, but easy to waste your money by overdoing probiotics. It's just not necessary. Don't do it.

5. Read the reviews

A probiotic is either going to work or it isn't. Whether it's diarrhea, yeast, itching, allergies, or whatever, check out the reviews and see if other cat owners with your issue have had success.

Something that actually works!
from JR D., California
" Something that ACTUALLY works! Probiotic Miracle was the total answer to my cat's tummy problems! I've tried diet changes, feeding schedule changes, additives - EVERYTHING - but this was what she needed all along - I saw results within a couple of days. No wonder you call it a miracle :) We couldn't be happier!!"

"I had no idea that probiotics for cats worked such great results. I've tried so many things with my older cat, vitamins and everything, but just by adding the probiotics made all the difference in her health! Thank you!!!"

5 Star Review
Fixed her poops!
from Eric C., Nevada
"Pardon my candor, but shiba had the worst runny, diarrhea poops almost every day no matter what we fed her. I wish I had found this probiotic long ago, it would have saved us so much time, money, and headaches! We use about a half scoop once per day and she has perfect poops. Thanks!"

5 Star Review
An Absolute MUST and surpassed all my expectations!
from Whitney D., California
"Our cat was barfing hairballs fairly often and had frequent bouts of diarrhea (usually not even making it to the litter box). We tried yogurt, everything. I take probiotics myself and give to my dog as well, so thought I should also supply to my cat, and what do you know? She's amazing. Beyond great digestion, her overall health has taken a giant leap forward, less shedding, teeth look great, and no more diarrhea. Probiotic Miracle is a great product!"
