Your cat's Health is our life's work™
We started PrimalCat for the cats who need a little more support — and for the humans up late at night wondering what would actually help.
Our mission is to support cats who need a little more.
We formulate every PrimalCat product around the cats most supplement brands overlook — the ones with watery eyes, gooby mornings, sniffly noses, or just an immune system that could use some help. Made in the USA. Built for the long haul.
We're here to be your second opinion.
As cat parents, we want what's best for our animals — but the vet visit is twenty minutes, the internet is a maze, and the supplement aisle is mostly dog stuff with a cat on the label.
So what if you had a partner who actually understood what those tough mornings look like? Someone who could tell you what the L-Lysine dose is supposed to be, and why most chews don't have enough of it?
That's the partner we're trying to be.
A partner who goes beyond the label.
We don't slap "immune support" on a fish flavor and call it done. Every PrimalCat chew is built around clinically meaningful doses of ingredients with real research behind them — sourced from suppliers who can produce a Certificate of Analysis we'd put our names on.
That includes high-mannan beta-glucan, bovine colostrum standardized for IgG, marine omega-3s tested for heavy metals, and a probiotic strain matrix that survives the chew matrix — not just the lab.
A partner who leans into the science.
We work with US manufacturers operating under cGMP standards, and we ask for third-party lab work on the inputs that matter most — heavy metals, microbial limits, and active-ingredient potency. The COAs aren't a marketing prop. We read them, we flag them, and we rework formulas when something looks off.
Our customers keep us honest. When something doesn't work for a cat, we hear about it — and that feedback drives every reformulation we run.
A partner you can actually trust.
Just the science.
No "miracle" claims.
No vague proprietary blends hiding 12mg of the active ingredient.
No fish-flavored fillers dressed up as functional nutrition.
Just what your cat actually needs. In doses that actually matter.
When Milo started struggling, I wanted something formulated by someone who'd actually been in my shoes — counting sneezes, googling ingredient doses, terrified the next morning would be worse than the last. That product didn't exist. So I built it.
Built on trust, backed by science,
tailored for your cat.
Most "immune chews" are made for dogs first and re-pitched at cats. Ours is the opposite — we started with what cats actually need, and built outward.
We formulate for the root cause, not the symptom on the box.
We are committed
to quality.
We stay at the front of feline supplement science by combining peer-reviewed research with expert formulation input. Every chew is built to deliver the dose on the label — verified by independent lab work on the inputs that matter.
Ingredients from places that actually matter.
Our L-Lysine is pharmaceutical grade. Our colostrum is first-milking, IgG-standardized. Our omega-3s come from wild-caught marine sources, not the cheap stuff. We pay more for inputs because cats don't get a do-over on the things that matter.
