The 10 Best Probiotics for Cats
1. Dr. Mercola Complete Probiotics — Best Overall
With an outstanding mix of price and performance, Dr. Mercola’s Complete Probiotics for Cats & Dogs easily earns our nod as the best overall probiotics for cats. While it doesn’t come in a large container, the small dosage means that it can last a long time.
This probiotic helps with both your cat’s overall energy level and digestive health, and it’s easy enough to administer, even to picky eaters. Dr. Mercola loaded this probiotic formula with 58 billion colony-forming units (CFUs) of 14 different beneficial bacteria strains, which makes it an extremely effective option to boost your cat’s immunity.
It’s a great choice at a great price, and our top pick for overall best probiotics for cats.
2. Pet Naturals Daily Probiotic Cat Chews — Best Value
|Size:||1.27 ounces — 30 count|
If you’re on a tighter budget and need a probiotic for your cat, check out Pet Naturals Daily Probiotic Cat Chews. It’s an extremely affordable product that you can use to regulate your cat’s digestive health, even though it doesn’t have as many CFUs as some other probiotics.
While it does help regulate digestive function, it’s not as effective as some other options out there. Since they’re treats instead of a powder, they’re easy to administer, and each container lasts a full month.
With their outstanding duck flavor, cats love them, and with their low price, it’s easily the best probiotic for cats for the money!
3. NWC Naturals Total-Biotics Probiotic — Premium Choice
|Size:||2.22 ounces or 8 ounces|
If you’re not worried about how much you’re spending on your cat’s probiotics, the NWC Naturals Total-Biotics Probiotic is exactly what you want. It’s expensive, but it’s also one of the best products to sort out whatever your cat needs help with.
Not only does it work wonders on their digestive system, but it also helps with food sensitivities, immune health, skin health, coat health, and more. This supplement is GMO-free and easy to administer. Furthermore, it uses a formula that gives it an excellent absorption rate, which adds to its effectiveness.
Another perk is that there are two size options to choose from, which means you can try out the smaller size, and then if it works for your cat, purchase in bulk to save money.
It’s definitely an expensive option, but considering all that it does and how effective it is, it’s an outstanding choice for your cat.
4. VetriScience Probiotic Duck Flavored Chews – Best for Kittens
|Size:||2.54 ounces — 60 count|
Kittens have unique dietary and developmental requirements, so it makes sense that their probiotics should tailor themselves to their unique needs. That’s exactly what you get with VetriScience Probiotic Everyday Duck Flavored Soft Chews.
While it technically works just fine with older cats, the fewer CFUs means that one treat-style soft chew is the perfect amount for a small kitten.
There are 60 chews in every package, and once you factor in its low price tag, you’re getting an extremely affordable probiotic that will last your kitten for quite a while. With VetriScience Probiotic Everyday Duck Flavored Soft Chews, you can get your kitten started off on the right paw!
5. Particular Paws Probiotic Powder
The Particular Paws ProBiotic Powder excels at reducing the symptoms and severity of UTIs, so if that’s the reason that you’re putting your cat on a probiotic, it might be the best choice out there. It also boosts your cat’s energy levels and improves their overall coat health, making it a win-win-win. While it’s a slightly expensive option, it comes in a large container size that helps offset the cost.
We do wish that it was a cat-specific formula, but that’s a small complaint if it works at controlling your cat’s UTIs!
6. Pet Ultimates Probiotics Cat Supplement
An outstanding powder-style probiotic for your cat is the Pet Ultimates Probiotic Cat Supplement. It’s an extremely effective formula that uses 20 different species of beneficial bacteria to improve your cat’s digestive health, along with a few other benefits.
It does this with a cat-specific formula that’s easy to administer because all you need to do is sprinkle a bit on their food!
That said, while it’s an effective option with tons of different probiotic strands, it is expensive and only comes in small containers. So, not only will you have to spend more up front to get it, but you’ll also have to purchase it more often. But if it’s what your cat needs to get their digestive health under control, then it’s worth every penny.
7. NaturVet Advanced Probiotics & Enzymes Plus
|Size:||4 or 8 ounces or 1 pound|
If you’re serious about keeping your cat on a probiotic for an extended period, you need to find an option that lets you purchase in bulk. That’s exactly what NaturVet Advanced Probiotics & Enzymes Plus offers. You can try out the small 4-ounce option, and if you end up keeping your cat on it, you can purchase 1 pound at a time to save money.
NaturVet Advanced Probiotics & Enzymes Plus is great for keeping your cat’s digestive health in check, and it does a great job tackling any digestive problems that your cat might already have. However, if you’re looking for a probiotic that provides more benefits amidst a wider array of applications, this isn’t it.
But since it has both probiotics and digestive enzymes, if your cat is having any digestive problems, you’ll be hard-pressed to find a better option out there.
8. Nusentia Probiotic Miracle Premium Blend
|Size:||1.55 or 4.62 ounces|
If you’re looking for a simplistic probiotic formula for your cat to try, Nusentia Probiotic Miracle Premium Blend is an outstanding choice. It doesn’t use any by-products, and it even limits the number of probiotics in the powder.
While this might sound limited, these six species of probiotic bacteria have well-researched benefits for your cat’s digestive tract. This formula helps to treat loose stool and diarrhea, clear excessive yeast, and maintain healthy digestion with better nutrient absorption and improved toxin and waste elimination. In addition, it also improves skin and coat condition and helps keep away smelly breath and an improved overall body smell.
This product comes in two size options, so you can try it out before making a large purchase, even if it is a bit expensive.
9. Finest for Pets TummyWorks Probiotics & Digestive
If you’re looking for an affordable yet effective probiotic option, the Finest for Pets TummyWorks Probiotics & Digestive probiotic powder can get the job done. It uses 10 different probiotics and six digestive enzymes to get your cat’s digestive health on track.
It comes in a large container that ensures that you won’t need to replace it any time soon. Of course, the flip side is that it only comes in that size. So, you can’t really try it before you buy a large amount of it — you just have to take that leap of faith.
Considering this is not a cat-specific formula, that’s a big leap of faith to take, but it usually doesn’t disappoint.
10. Fera Pet Organics Probiotics With Organic Prebiotics
The Fera Pet Organics Probiotics With Organic Prebiotics uses 11 strains of live probiotics to boost your cat’s digestive health, and it has tons of CFUs that help get the job done.
Pair those with the fact that this powder is extremely affordable and promotes skin health, and you’re getting a top-notch product. However, while there’s plenty to love about this probiotic, there’s only one product size to choose from, and it’s not a cat-specific formula.
While it might work for your cat, there’s no doubt that there are more effective choices out there.
Buyer’s Guide: How to Choose the Best Probiotics for Your Cat
If you still have questions about probiotics for cats after reading through the reviews, you’re not alone. That’s why we developed this comprehensive buyer’s guide, to walk you through everything that you need to know about cat probiotics before you select the best probiotic for your cat.
What Are the Benefits of Probiotics for Cats?
There are tons of potential benefits to adding a probiotic to your cat’s diet, but you don’t need to take our word for it. There are plenty of scientific studies that link probiotics to health benefits for cats.
Even better, there’s little to no evidence that adding a probiotic to your cat’s diet leads to any adverse health risks. It’s a great way to improve your cat’s health — even if they’re already healthy!
Should All Cats Have Probiotics?
Since there’s little to no evidence that adding a probiotic to a healthy cat’s diet has any adverse effects, there’s no reason that you can’t put your cat on a probiotic to keep them as healthy as possible!
This is especially true when you consider that keeping your cat on a probiotic all the time increases their overall GI health and reduces the likelihood of problems in the future. So, while not all cats need probiotics, there’s no harm to giving some to your cat, and there are actually a few benefits of doing so!
Considering how affordable it can be to put a cat on a probiotic, we think that unless your cat has an underlying condition, all cats should have probiotics.
Can Cats Have Too Many Probiotics?
Just like anything, your cat can definitely have too many probiotics. Common symptoms include vomiting, diarrhea, or other negative side effects. If you notice these symptoms shortly after putting your cat on a probiotic, there’s a good chance that they’re allergic to something in it.
However, if you notice any of these symptoms after upping their probiotic dosage, there’s a decent chance that you have your cat on too many probiotics, and you need to lower their dosage a bit.
How Long Does It Take for Probiotics to Work in Cats?
All good things take time and probiotics are no different. The exact amount of time that you need to wait until you can see results depends on your specific cat, but you should expect results anywhere from a few days to a few weeks.
If your cat isn’t showing improvement in symptoms after a month, there’s a good chance that you’re not going to see any changes later.
If you finished the reviews and the buyer’s guide and still don’t know which probiotic to go with, why not try Dr. Mercola’s Complete Probiotics? It’s our pick for overall best probiotic for cats because it expertly combines performance and price.
However, if you don’t want to spend as much, you can try Pet Naturals Daily Probiotic Cat Chews. While it’s not as effective as some of the more expensive options, you can reap the benefits of cat probiotics without spending much at all!
The most important thing is that you order something for your cat, so they can start feeling better than ever as soon as possible.
