THE ONE RULE

In Japan, Cats Live Past 25. Most Here Never Reach 12. It Comes Down To One Thing.

In Japan we have one rule: keep a cat strong from the inside, and they live a long life. One PrimalCat chew a day gives back the protection their body was born full of and quietly loses every year.

It Is Not The Food. It Is Not The Breed. It Is One Thing We Have Done For Hundreds Of Years.

Most cats in America never reach 12. Ours live past 25, and they have for a very long time. It is not luck, and it is not the blood they were born with.

In Japan we have one rule. Keep a cat strong from the inside. Do that, and they live a long life. Fail, and nothing else you do will matter.

An older cat kept

So every day, we give our cats one thing. In Japan we call it Rakutoferin. You would call it Lactoferrin.

It is not a medicine. It is a protein. The very first thing a mother gives her kitten, in her milk, before their eyes are even open. It is what their body uses to protect itself, from the first hour of life. A young cat is full of it.

But here is what no one tells you. Every year, their body runs lower on it. And you can watch it happen.

The jump to the
The whole afternoon

The jump to the top shelf they stop making. The whole afternoon asleep in the sun. The slowing down everyone calls old age.

That is not just age. That is the protection wearing thin. And once it goes, the years go fast.

So we give it back to them. Every single day. That is the whole secret. There is nothing else.

You buy the good food. The expensive kind. You think that is enough. Good food will feed a cat. It will not give back what the years take away.

PrimalCat makes it the proper way, in one simple chew a day. You hand it over, they do the rest.

One chew a day,

Our Belief:

Daily Immune & Eye Support Is a VITAL Part of EVERY Indoor Cat's Routine.

When their immune

But let's be honest, pills and eye drops are a nightmare.

If you've ever tried to force a tablet down a squirming cat, you know how much it sucks to keep doing something that turns into a daily fight. We got rid of all that.

One tuna-flavored chew a day supports your cat's eyes and immune system, and most cats think it's a treat, not medicine.

After all, they shouldn't have to fight us to feel better, right?

Hey, I'm Jackie!
Founder of PrimalCat

Jackie, founder of
Jackie
Founder of PrimalCat

Years ago my cat struggled with the same thing yours might be dealing with now:

Watery, crusty eyes
Constant sneezing
Flare after flare
A run-down immune system

And more that I won't bore you with...

Run-down cat
Same cat after,

Every flare-up felt like a battle. The vet visits, the drops, the pills he'd spit right back out.

I did a good job managing it, but I was tired of just managing the symptom instead of supporting his body.

Then everything changed when I stopped chasing single ingredients.

I turned into a low-key cat-nutrition obsessive.

I Tried Everything From:

Lysine powders
Prescription drops
Immune boosters
Diet changes
Probiotics
Vet visit after vet visit

And don't get me wrong... some of those things help. But none of them were the game changer I was looking for on their own.

I wanted the thing with the biggest impact that was also easy to do and didn't cost a fortune.

Here's why I fell in love with whole-prey, multi-ingredient support:

Colostrum + probiotics for gut-led immunity
Taurine + antioxidants for the eyes
Omega-3s to calm irritation
Real doses, not label dust
One chew instead of a handful of pills

Here's The Problem...

Doing all of that yourself is expensive, confusing, and honestly exhausting (and yes, I tried).

If you've tried

I wanted all the benefits, but in an easy way I didn't have to fight my cat to do.

That's when PrimalCat was born

(now trusted by thousands of cat parents who've taken back their cat's comfort).

One single tuna chew a day that delivers the exact eye & immune support your cat actually needs.

Frequently Asked Questions

Does this replace my cat's food or multivitamin? +

PrimalCat is a daily support chew, not a replacement for a balanced diet. It fills the gaps a modern bowl leaves behind, targeted eye and immune support your cat's food isn't built to deliver. Keep feeding your cat normally and add one chew a day.

Is this batch tested? +

Yes. Every batch is tested for quality and made in a facility that follows strict manufacturing standards.

Can kittens take PrimalCat? +

PrimalCat is formulated for adult cats. For kittens under one year, check with your veterinarian on the right serving first.

What's the best time of day to give it? +

Any time that's consistent. Most cat parents give it with breakfast so it becomes part of the daily routine. Consistency matters more than timing.

What are the ingredients in PrimalCat? +

Eight targeted actives, colostrum, a probiotic, taurine, omega-3, beta-glucan, lactoferrin, and lutein, plus the amino acid support cats need, all in a tuna-flavored soft chew. See the full Supplement Facts panel above.

Can senior cats take this? +

Absolutely. Many of our customers have senior cats, and the antioxidant and immune support is especially valuable as cats age.

How many servings per bag? +

Each container holds 45 servings. One tub is a 30-day supply at the daily serving. See the Supplement Facts panel above for exact amounts.

What's the difference between PrimalCat and a plain lysine chew? +

Single-ingredient lysine chews only do one thing. PrimalCat combines eight actives at real doses, gut, immune, and eye support together, so you're supporting the whole system, not just one piece of it.

Will PrimalCat upset my cat's stomach? +

It's gentle and includes a probiotic blend that supports digestion. Introduce it with food and most cats take to it easily.

If my cat has a medical condition, can I still give this? +

PrimalCat is a supplement, not a medication. If your cat has a diagnosed condition or takes prescriptions, check with your veterinarian before starting anything new.

What if my cat doesn't like it or I don't see results? +

You're covered by our 60-Day Money-Back Guarantee. If your cat won't eat it or you don't see a difference, reach out and we'll make it right, no hassle.
