Digestion Biotics

Is it just a sensitive tummy — or has her gut never really settled? You've switched her food, watched the litter box and hoped it would pass, but recurring soft stool usually isn't something to just live with: it's a gut that's out of balance. ivvi Digestion Biotics is one creamy, real-tuna lickable sachet a day that brings a heat-treated probiotic, prebiotic fiber and gut-soothing pumpkin together to help settle her stomach and support firm, healthy stools.

Supports a balanced gut microbiome — a heat-treated Bifidobacterium longum postbiotic plus prebiotic FOS work together to help the good bacteria flourish.
Helps maintain firm, consistent stools — gentle soluble fiber from pumpkin and flaxseed supports normal digestion and one predictable litter box.
The pumpkin owners trust — already mixed in — real pumpkin's soluble fiber and moisture support a settled, comfortable tummy, with none of the can-and-spoon hassle.
A picky-cat favorite — a creamy treat made with real tuna that most fussy cats happily lick right up — no powder to mix, no capsule to hide.
One easy sachet a day — clean, vet-formulated daily digestive support with real tuna, no by-products, no artificial flavors or colors.

Daily gut support goes a long way for a settled tummy.

My cats pounce the moment I offer one - a tuna snack with digestion-focused ingredients they love.

Heat-Treated Probiotic (Bifidobacterium longum)

A gentle, heat-treated Bifidobacterium longum postbiotic that helps support a balanced gut microbiome and the gut's natural barrier — the inactivated form is stable and stomach-friendly.

Prebiotic (FOS)

Fructooligosaccharides are a prebiotic fiber that nourishes your cat's beneficial gut bacteria, helping a healthy microbiome flourish — the perfect partner to the postbiotic.

Pumpkin Flesh

Naturally rich in soluble fiber and moisture, pumpkin — the remedy so many cat owners already trust — supports normal digestion and helps keep stools consistent and comfortable.

Flaxseed

Soft mucilage fiber that supports normal stool consistency, plus plant-based omega-3 (ALA) — a soothing, wholesome addition to the digestive blend.

Pumpkin Seeds

Ground pumpkin seeds add extra wholesome fiber and naturally-occurring nutrients to round out the fiber blend that supports your cat's everyday digestion.

Real Tuna

A creamy base of real tuna that cats genuinely love — so daily digestive support becomes something she looks forward to, one easy lickable sachet a day.

🩺 From our veterinarian

A vet's take on feline digestion

“Her poop has never really been normal — is it just a sensitive stomach, or something I should worry about?”

It's one of the most common questions I hear, and it comes from a real place: cats are creatures of routine, and when the litter box keeps changing — soft one day, a mess the next — it's unsettling for everyone. Most of the time, recurring digestive upset comes down to a gut microbiome that's simply out of balance, often nudged off course by a diet change, a course of antibiotics, or everyday stress.

That's the idea behind a daily digestive supplement: instead of chasing each flare-up, you gently support the gut environment every single day. A heat-treated Bifidobacterium longum postbiotic helps support a balanced microbiome and the gut's natural barrier, while prebiotic FOS feeds the beneficial bacteria already living there — a postbiotic-plus-prebiotic pairing that works together.

Alongside them sits the fiber owners already reach for: pumpkin. Its soluble fiber and natural moisture help support normal digestion and consistent stool quality, and flaxseed adds soft, soothing fiber plus a little plant omega-3 — with pumpkin seeds rounding out a wholesome fiber blend. It's the home remedy you'd reach for anyway, already measured and mixed in.

Of course, no supplement replaces your veterinarian. If your cat has ongoing vomiting, weight loss or diarrhea, please have her checked — this is everyday digestive support, meant to sit alongside good veterinary care, not in place of it. Introduce it gradually so her stomach can adjust.

What makes it easy to actually use day after day is the format. ivvi Digestion Biotics is a creamy, real-tuna lickable — no powder to mix and no capsule to hide — so even fussy cats look forward to the support that's quietly working in their favor.

1. Heat-treated B. longum and the feline gut during diet change

Wang et al., 2024 – In a randomized controlled study, cats given a heat-treated Bifidobacterium longum postbiotic with prebiotic fiber showed improved gut-barrier markers (higher fecal sIgA, lower “leaky-gut” LPS) and more protective gut bacteria through an abrupt diet change.

2. Live and heat-treated Bifidobacterium both active in cats

de Souza Junior et al., 2025 – Over 90 days in 36 adult cats, both the live probiotic and the heat-treated postbiotic form of Bifidobacterium were safe, well tolerated and produced comparable physiological responses — confirming the inactivated form remains biologically active.

3. A heat-killed Bifidobacterium improved gut comfort

Andresen et al., 2020 – In a multicenter randomized trial, a non-viable, heat-inactivated Bifidobacterium significantly improved a composite gut-comfort score versus placebo — showing postbiotics can deliver benefit without live cells.

4. A probiotic and fewer days of loose stool in cats

Bybee et al., 2011 – In a double-blind, placebo-controlled trial in a shelter, cats fed a beneficial-bacteria supplement had significantly fewer episodes of diarrhea lasting two or more days than cats on placebo.

5. Prebiotic FOS shifts the feline gut toward beneficial bacteria

Sparkes et al., 1998 / Barry et al., 2010 – Adding fructooligosaccharide prebiotic fiber to cats' diets nudged the fecal microbiome toward a more balanced profile — supporting the role of prebiotic fiber in a healthy, well-fed gut.

6. Flaxseed adds omega-3 and soothing fiber for cats

Panasevich et al., 2022 / Soltanian et al., 2018 – Ground flaxseed significantly raised omega-3 (ALA) blood levels in cats without harming stool quality, and its soluble mucilage fiber is shown to support normal, comfortable stool consistency.

Ericka M. 4/5 Verified September 7, 2026

I have a 19-year-old cat who has always had gastrointestinal issues. She’s tiny—only 4.5 lbs. A whole packet seems to be too much for her and seems to make her go more frequently. I cut it back to 1/3 of a packet daily, and she’s doing much better. She loves it and thinks it a treat. She follows me around meowing for more.

Floyd (cat) was less than delightful regarding his GI tract. I was hoping the Digestion Biotics might firm up his poo. I have already noticed less vomiting & hairballs He does seem a bit more relaxed. Most of all he LOVES the biotics. I was hoping he wud. I bought Taurine over the Web. It was powdered form & a scoop sprinkled over the cat's food.......diarrhea...need i say more...So with Floyd's permission we're sticking w/ your Digestion Biotics.

I just got it yesterday and gave it to my two kitties this morning. They love it! It will be good for them. Since they are very young kittens I gave them only half each of a packet. And if all goes well which I am sure it will I will be purchasing again. Thank you so much!

Frequently Asked Questions

Everything you need to know about the ingredients, quality, and care behind our award-winning treats.

How much should I give my cat each day?

Just one sachet a day — that's the full daily serving. Each box has 30 sachets for a one-month supply. You can offer it straight from the sachet as a lickable treat or spoon it onto her food. Introduce it gradually over the first several days so her stomach can adjust comfortably, especially if she has a sensitive tummy.

How soon will I see a difference?

Digestive support is gradual, not instant. Some owners notice a settled tummy within a few days, but the gut microbiome takes time to find its balance, so we recommend giving it daily and being patient — many owners see firmer, more consistent stools over about two to three weeks of steady use. Every cat is different, so give it a fair, daily run before you judge it.

What if my cat is picky and won't eat it?

This is where the creamy, real-tuna formula shines — most fussy cats happily lick it right up, with no powder to mix or capsule to hide. That said, we'll be honest: no single flavor wins over every cat. If yours turns up her nose, our 180-day money-back guarantee means you can try it completely risk-free.

Could a probiotic actually make her stool worse?

It's a fair question — some supplements can cause a little extra gas or softer stool at first as the gut adjusts. That's exactly why we introduce it gradually, and why the probiotic here is heat-treated (a stable “postbiotic” form) rather than a live culture, paired with pumpkin's soluble fiber, which helps absorb excess moisture. The goal is gentle, settling support — not an aggressive change. If her stool stays loose, ease back the amount and check with your vet.

Does my cat even need a probiotic?

Not every cat does — and we'd rather be honest than oversell. It tends to be most helpful around the moments that upset the gut: a food or diet change, a recent course of antibiotics, a stressful event or move, or simply a cat whose stool has never quite settled. If that sounds like yours, daily digestive support is an easy, gentle thing to try.

Can I give it if my cat has a diagnosed digestive condition?

Think of this as everyday digestive support for healthy adult cats, not a treatment for any medical condition. If your cat has ongoing vomiting, weight loss, or diarrhea, or has been diagnosed with a digestive condition, please see your veterinarian — this is meant to sit alongside their care, not replace it. Always give your vet a quick heads-up if your cat is on medication.

What's your return policy?

Every order is backed by our 180-day money-back guarantee. Give it an honest, daily try, and if you or your cat aren't happy for any reason, just reach out and we'll make it right — no hassle. That way the only thing you have to lose is the litter-box surprise.
