Our Science

It's not magic. It's fiber.

We're new, so we won't show you a wall of reviews we invented. Instead, here's the real, checkable science behind one clean ingredient — and, just as honestly, what it can't do.

Pumpkin's is a food topper, not a medicine. For frequent, severe, or new symptoms, see your vet first.

82–93%
of cats' chronic constipation cleared up on a fiber-based diet.
Pumpkin is that fiber — the soluble kind firms things up, the insoluble kind keeps them moving.

That study used psyllium fiber in chronically constipated cats — not pumpkin, and not every tummy trouble. We share it because pumpkin is a natural source of the same two fibers, and we'd rather tell you exactly what the research says.

Two fibers, two jobs.

Settle.

Soluble fiber absorbs water and forms a gentle gel that helps firm up loose stools. source

Move.

Insoluble fiber adds bulk that keeps things moving — and helps swallowed hair pass through instead of coming back up. source

What the research actually supports.

Fiber is the go-to dietary tool for feline digestive upset.

Veterinary sources describe fiber as the mainstay for managing everyday and idiopathic digestive trouble in cats. source

Fermentable fiber feeds the good bacteria in a cat's gut.

Soluble fiber is broken down into short-chain fatty acids that nourish the cells lining the colon. source

Pumpkin is a real source of both fibers.

Pumpkin naturally supplies a mix of soluble and insoluble fiber — the two kinds that settle a cat's gut. source

Proof you can check.

Not a claim you take on faith — the things you can actually verify.

And here's what it can't do.

Pumpkin is gentle daily support, not a cure. It won't fix a chronic condition — that takes a vet, and single-ingredient fiber has limited evidence there. And though pumpkin has vitamins on paper, cats barely absorb them, so we sell it for its fiber and moisture, not as a superfood. Pair it with fresh water. That's the whole, honest story.

Every source, in one place.
