Frequently Asked Questions +

What do probiotics do for cats?

Probiotics are live bacteria that help promote healthy microbes in a cat’s gut, supporting digestion and nutrient absorption. PurrBiotics can be used to help with occasional diarrhea, loose stools, gas, and bloating. Because gut health is closely linked to immune health, daily use can also support your cat’s natural defenses and overall vitality.

How long does it take for probiotics to work in cats?

Every cat is different. Some owners notice improvements in digestion, stool quality, and energy within the first month, while others see the most significant results after 2–3 months of consistent daily use. For best results, we recommend giving PurrBiotics for at least 90 days.

What probiotics are good for cats?

There are specific probiotic strains shown to benefit feline digestion and immune health. PurrBiotics was formulated by experts to include:

  • Lactobacillus acidophilus
  • L. plantarum
  • Bifidobacterium animalis lactis
  • Enterococcus faecium
  • Bacillus coagulans
  • Saccharomyces boulardii

How should I give PurrBiotics to my cat?

Simply open one capsule and sprinkle the tasteless, odorless powder over your cat’s food once per day. If you feed dry kibble, lightly wetting the food can help the powder stick. Most cats accept it easily, but if your cat is cautious with new foods, start with half a capsule for a few days, then increase to a full serving.

Are these probiotics safe for kittens?

Yes — PurrBiotics is suitable for cats and kittens 6 months and older. If your kitten is younger or has special health needs, consult your veterinarian before starting.

Is this probiotic suitable for cats with special dietary needs?

Yes. PurrBiotics is free from artificial flavors, fillers, and common allergens. However, if your cat has specific dietary sensitivities or medical conditions, we recommend checking with your veterinarian to ensure compatibility.

How does PurrBiotics differ from other cat probiotics?

Unlike chews or tablets that can be hard for cats to take, PurrBiotics is a fine powder that blends seamlessly with your cat’s daily meals. It’s made with clinically studied, cat-specific strains that survive stomach acid, ensuring they reach the gut alive and effective.

Shipping & Returns +

We ship all orders within 24 hours, and delivery typically takes 2–4 business days.

Your order is backed by our 30-Day Money-Back Guarantee. If you don’t notice results, or if your cat won’t take the product / doesn’t like it, simply contact us within 30 days for a full refund — no questions asked.

So many cats deal with tummy issues and weak immunity. What I like about PurrBiotics is that it’s made for cats — and the strains actually survive stomach acid. When used daily, I’ve seen results in just weeks.”

Review by Lindsey
Lindsey, 17 Healthier Cat
Lindsey will be 17 September 1. She was becoming lethargic with a diagnosis of Stage 1 kidney disease. Her coat was a disaster and she was drinking a lot of water. After only a few days, she was a different cat. She has a good appetite, drinks normal amounts of water, her coat has improved. I believe she has a new lease on life. Thanks for an amazing product.
Review by Helen
Helen, 14 Healthier Cat
My beautiful kitty is about 14 and has a history of medical problems. She is on a fancy diet from Canada but I had to find something that would help her go to the bathroom easier. I had to stop the straining and discomfort. This is my first bottle, and I really think it is working. She is crying much less and isn't circling in the litter as much. So I say five stars especially since she gets excited when I take out the bottle. She inhales them!
Review by Luke
Luke, 19 Healthier Cat
Our cat always had awful gas and breath from a sensitive stomach. The vet gave us probiotic sachets, but they were so expensive we couldn’t keep it up. Then we found PurrBiotics. After 6 months on subscribe & save, the change has been huge — she went from being smelly almost every day to hardly ever. It feels amazing to finally cuddle her without the stink. This has been such a relief for us and for her.
Review by Luna
Luna, 15 Healthier Cat
Luna is 15 and slowing down. Her fur was greasy, she drank so much water, and I thought I was losing her to old age. A month into PurrBiotics, she’s eating normally, drinking less, and she even gained a little weight back. Seeing her nap in the sun with a glossy coat again makes me tear up. It’s like she got a second chance.
Review by Pepper
Pepper, 12 Healthier Cat
I was honestly at my wit’s end with my boy throwing up hairballs every other day. I’ve tried changing food, brushing more, even those hairball treats — nothing stuck. A friend recommended PurrBiotics and wow… total turnaround. He hasn’t hacked up in weeks and his coat actually looks silky again. Didn’t think probiotics would be the thing, but here we are.
Review by Oreo
Oreo, 6 Healthier Cat
Our vet used to joke that Oreo had a “nervous stomach” because literally anything set him off — new food, moving furniture, even if the neighbor’s dog barked too loud 🙄. Diarrhea after diarrhea. Since giving him PurrBiotics, he’s so much more stable. No flare-ups in weeks, and he actually seems more relaxed overall.
Review by Mochi
Mochi, 4 Healthier Cat
If you have a cat with stinky litter, PLEASE try this. Mochi’s box used to clear the whole room, no matter what litter we bought. After a couple weeks on PurrBiotics, the smell is basically gone and she’s not gassy anymore either. Even my partner noticed, and he never notices anything. Best money I’ve spent.
Review by Simba
Simba, 7 Healthier Cat
Simba (7) was the king of puke. Food, foam, hair, you name it. It broke my heart because he would look so uncomfortable after. Started him on PurrBiotics and I swear within days, the vomiting slowed, and now it’s almost nonexistent. He’s eating happily and even chasing toys again. I’m shocked but so grateful.

Frequently Asked Questions

Will my cat eat it? +

Yes! PurrBiotics is completely tasteless and odorless, so even picky eaters don’t notice it. Just sprinkle it over food and mix—no pills, no stress, no battles at mealtime.

How fast will I see results? +

Many cat parents notice changes within a couple of weeks—like firmer stools, less vomiting, or better energy. For deeper benefits (stronger immunity, shinier coat, long-term gut balance), consistency is key: most see the full transformation by Month 2–3.

Is it safe for seniors or kittens? +

Absolutely. PurrBiotics is designed for daily use at every age, from playful kittens to senior cats who need extra support. Just follow the serving instructions on the label for the right amount.

Why choose PurrBiotics over other probiotics? +

Not all probiotics are created equal. PurrBiotics is:

  • Cat-specific (formulated for feline gut health, not generic human strains)
  • Acid-resistant (survives stomach acid to reach the intestines alive)
  • Tasteless & odorless (cats actually eat it!)

That’s why thousands of cat moms see results where other products failed.

What do probiotics do for cats? +

Probiotics are live bacteria that help to promote good microbes in a cat’s gut, supporting healthy digestion. Probiotics for cats can be used to support occasional diarrhea and loose stools and occasional gas and bloating. Additionally, because feline gut health can affect a cat’s immune system, using a feline probiotic supplement can help support your cat’s normal defenses and immune health.

How long does it take for probiotics to work in cats? +

Probiotics for cats and kittens can take up to 90 days of consistent use to see the best potential benefits. Each cat is different. Some felines see the benefits within month 1, and some see the best results from months 2 and 3 onwards.

What probiotics are good for cats? +

There are a variety of probiotic strains that are beneficial to cats. PurrBiotics’s Cat Probiotic was formulated by experts to include the following probiotics to support cat gut and digestive health:

  • Lactobacillus acidophilus
  • L. plantarum
  • Bifidobacterium animalis lactis
  • Enterococcus faecium
  • Bacillus coagulans
  • Saccharomyces boulardii

How should I give probiotic powder to my cat? +

To give your cat probiotic powder, simply open two capsules of PurrBiotics daily and sprinkle the powder over your cat’s food. If you feed your cat dry food, wetting the food a bit first may help the powder adhere better.

Our supplement is tasteless and odorless, but still when a new element is added to a cat’s daily food, they may eat less at first while they adjust. If you have any concerns, please consult your veterinarian.

Is this probiotic suitable for felines with special dietary needs? +

While PurrBiotics is designed to fit into many feline diets, we recommend consulting with your veterinarian if your cat has special dietary requirements or sensitivities to ensure compatibility with their health needs.

How does PurrBiotics's powder differ from other probiotics for cats? +

PurrBiotics's powder is designed to blend seamlessly with your pet's food, making it easier for you to support their gut health every day. Unlike cat probiotic chews and tablets, our powder formula works subtly during mealtimes, designed to provide comprehensive gut health support.
