Choosing the best probiotic for your cat

portrait of tortoiseshell cat

Hopefully, you found my reviews useful and helped you decide on the best supplement for your kitty. As with all health products both for human and pets, results vary.

What may work well for one my not work so well for another. Also, cats are notoriously fussy, and some crafty kitties seem to know when you’ve carefully hidden tablets in their food!

Most probiotics I’ve shared here contain natural flavorings designed to appeal to cats so you should be fine. However, for the very fussy you could always try adding to favorite treats.

Always look for products containing natural ingredients. In addition, try and avoid those with fillers such as grain or corn.

While these aren’t harmful, they provide very little nutritional benefit. Also non-GMO is always a good sign, as well as veterinarian formulated.

Your Cat’S Gut Health

Newborn kittens have a clean, healthy gut free from bad bacteria. Soon after birth, the mother passes healthy gut bacteria onto the newborns. This is done through breast feeding, and cleaning.

It doesn’t take long though before bad bacteria start entering the kitten’s guts, and there’s always a constant fight between good and bad. A lot of things can upset gut flora including antibiotics, food additives, medications, and even stress.

It’s not just us that suffer diseases caused by bad bacteria, but our pets as well. Taking control by providing them with a quality probiotic is the best way to ensure your cat or dog stays healthy.

Study has shown that many metabolic diseases begin in the gut. Although research applies to humans, it’s the same for cats and dogs as well.

In addition, probiotics are often used to treat gastrointestinal problems such as diarrhea and tummy upsets. This may prove effective for your cat, but always seek advice from your vet if symptoms worsen.

Probiotics As A Treatment For Diarrhea In Cats

If your kitty develops diarrhea it can be worrying. It’s not uncommon in cats, and there are many causes. Just as in people, a sudden change in diet may be the reason.

Also, antibiotics, parasites, and inflammatory bowel disease could trigger diarrhea in your cat. If bad bacteria overtakes the number of good bacteria in the gut, diarrhea can occur.

Probiotics contain live bacteria which are the good guys. Introducing them into your cat’s diet can quickly help return a normal balance of healthy bacteria in the gut.

This may help calm your cat’s diarrhea and reduce any pain or discomfort. However, results won’t be instant and may take up to a couple of days.

Actually, your vet may even recommend a short course of probiotics. It’s very rare to get any complications, and the benefits to your pet’s overall health are many.

NEVER let your cat get dehydrated as this can be dangerous. If your cat is reluctant to eat, try cooking her a piece of tasty chicken and add boiled rice.

In addition, a few teaspoons of water will help replenish fluids. If after a few days there’s no improvement you should see the vet as soon as possible.

Dehydration quickly leads to loss of fluids and deficiency in electrolytes. While often an injection of electrolytes works well, in severe cases a stay in the surgery and drip may be required.

How Probiotics Can Improve Bowel Health

Irritable bowel syndrome is very common in cats, and chances are your feline friend will develop it at some time or another in her life. It’s believed to be partly caused by commercial cat food.

Many brands contain high levels of grain, as well as additives and preservatives. It’s quite possible some of these ingredients could cause IBS.

You can easily learn how to make your own cat food, which is healthier, and free from additives. Also, adding a probiotic to your cat’s diet may help maintain healthy bowels, saving you money in vet fees!

Your Cat’s Immune System

Your cat’s immune system is very similar to yours with about 70% located in the gut. As previously mentioned many metabolic and inflammatory illnesses start in the gut.

Ensuring your kitty’s gut stays healthy can lower the risk of conditions such as diarrhea, infection, IBS, and gastroenteritis. This is why Introducing probiotics into your kitty’s diet may be beneficial.

Providing you choose a quality probiotic that’s specifically formulated for cats you should be fine. Any of the ones I’ve shared here would be ideal, though I can’t guarantee results.

Final Thoughts

I hope you’ve found this post on best probiotics for cats useful. We’ve covered quite a lot including a look at 6 of my top recommended probiotics.

As I don’t have any medical training I can’t advise on any health issues, but all products I recommend have been carefully chosen. If you have any concerns you must ask your vet first, especially if your cat is already on medication.

10 thoughts on “7 Best Probiotics For Cats And Proven Benefits”

  1. This is great awareness for cat owners. I used to have 3 cats when growing up and back then we never knew about this. But the fantastic research over the years, there is finally some science behind some illnesses and medication or supplements to help prevent these illnesses. I like the list of prebiotics too so people can start to try what’s best for their cat. Like you say, cats can be fussy and clever!!

    • Thank you Lee:) Yes, there’s a lot more scientific evidence nowadays that shows the health benefits of probiotics. This applies to both humans and pets, with similar benefits to both. I’m glad you like the products I recommended, and I’m sure even the fussiest of cats would be ok with them!

  2. I had never heard of probiotics for cats. Thankfully, my baby is quite healthy and doesn’t seem to have any issues. It’s too bad they can’t tell us when they feel sick. I recently got a recipe book for feeding cats homemade food. It’s going to take a while to convince me to actually try it. Thank you for posting this!

    • Thank you Cathy:) Yes, such a pity our cats are unable to tell us when they’re not feeling well! Glad you got the recipe book, and hope you get to try some of the homemade cat foods! I’m glad your cat is healthy with no issues. You may want to consider probiotics as she or he ages. Many diseases start in the gut, both for us humans and our pets:)

  3. I recently started ordering supplements on Amazon for my dogs, supplements for heart health and some others that contain fish oil and are good for their coat, bones, etc. I was also thinking of getting some good supplements for my cats, since they are outdoor cats and only come inside to sleep and also cuddle with me 🙂 It’s interesting to see Zesty Paws here since Amazon also recommended it to me in one of their promotional emails.
    Probiotics makes sense, especially since one of my cats is a hunter and he eats what he hunts. So, I guess that he could use some probiotics. The ingredients sound like he would eat them, having flavors I know he would like. Which one do you think is best for an outdoor cat?

    • Hi Christine, good to hear you’re giving your dogs supplements, especially fish oil. Yes, fish is great for heart, skin, coat, and joints. In fact, both dogs and cats gain similar benefits to us. Your outdoor cats would definitely benefit from probiotics. I don’t think any one in particular is best, as all promote gut health. Whether your cats spend all day outside or indoors any probiotic is good. The main thing is you get them to take it! Thanks for stopping by and glad this post was of help:)

  4. Hi Kathy,

    Before reading this article, I didn’t know that cats also need probiotic supplements, just like us. I personally don’t intake probiotics, but my parents do.

    Among all the choices, I will pick Pet Naturals Daily Probiotic since it’s the only one approved by NASC, so it gained my confidence in the product quality.

    My second pick will be Zesty Paws Probiotic Bites which combines two products in one. I’ve read another article of yours that coconut oil does good for cats. So, when I read that this product has coconut glycerin, I feel like, “This is it!”


    • Hi Matt, yes, probiotics are good for pets as well as humans. Both Pet Naturals and Zesty Paws are a great choice, and easy to administer. Zesty Paws has the edge though as you get salmon oil as well. Also, as you mentioned, Probiotic Bites contains coconut oil. Thanks for stopping by and glad you enjoyed this post:)

  5. Hey Kathy,
    I always love reading from you because you provide information in a clear and straight-forward way, touching on all important aspects of a particular topic.

    I learned so much from this post! As a cat lover, there is still so much I need to learn about how their gut works and how to take care of them. I am super surprised to learn that cats can certainly have IBS too! wow, i really had no idea!

    Anyways, I am impressed with the list you have curated because each one has the best amount of probiotics for our cute little felines! Personally I prefer the powdered type because I have seen cats take out tablets from their meals, regardless of how well they are hidden! However, do you think it is a good idea to crush the tablets into powder so to ensure they are getting their probiotic supplements in?

    • Hi Sasha, thank you for your kind comment:) Yes, it’s surprising how many diseases and ailments cats get that are similar to ours. I agree the powdered type is a good choice, but the chews are easy to administer. You don’t have to worry about your cat spitting them out as they’re formulated with a taste cats enjoy. With regard to your question about tablets, yes, you can crush them up and mix in with food. A good tip I’ve found through experience is mixing crushed tablets with a favourite treat! Thanks for stopping by and glad you enjoyed this post:)
