Stop the flare-ups before they start - with one simple dropper a day.
Up to 90% of cats carry feline herpesvirus. Once it's in their system, it never leaves - it just waits for stress, a cold snap, or a dip in immunity to come roaring back.
You've probably tried lysine treats before. Most cats won't touch them. And the ones that do? They're often packed with fillers that upset the stomach and make the next dose even harder.
PurrVita L-Lysine Drops disappear into any meal - no fighting, no refusing, no wasted money on treats that end up in the trash. Just consistent, daily immune support that actually gets inside your cat.
Because flare-ups don't warn you. One day they're fine - the next, you're wiping gunk from their eyes and listening to them struggle to breathe.
With one dropper a day, you can break the cycle and protect the sweet fur baby who depends on you for everything.
Peace of Mind for Every Cat Parent Who's Been There
If your cat refuses lysine treats: Finally, a form that disappears into their food - they won't even know it's there.
If you've tried everything and nothing sticks: No more wasted money on chews, gels, and powders that end up in the trash.
If you dread the next flare-up: Consistent daily support means you're not just waiting for the sneezing and goopy eyes to come back.
If you're tired of feeling helpless: It's one small thing you can do every single day to protect them
The PurrVita Story: Born from Love and Necessity
PurrVita was founded by cat lovers who witnessed the critical importance of taurine firsthand. After a beloved feline companion was diagnosed with a preventable heart issue linked to nutrient deficiency, our journey began. We realized that even quality diets could sometimes fall short. Driven by a mission to empower pet parents, we created PurrVita: a pure, potent, and easy-to-use taurine supplement. Our story is simple—it’s about providing every cat with the essential foundation for a long, vibrant, and healthy life, straight from our family to yours.

My vet told me years ago to try lysine treats for whiskers' herpes. She wouldn't touch them. Not one. I tried niding them, crushing them, everything - nothing worked. when she passed last year I kept thinking 'what if I'd found something she'd actually take?" I have a new baby now and I'm not making that mistake again. The drops just disappear into ner food. She has no idea. That alone is worth it to me

I lost my sweet boy Max to complications from feline herpes -- the eye ulcers got so bad toward the end. It still haunts me honestly. When I adopted Pip I was determined to stay ahead of it this time. The drops are just... easy. One squeeze, done. I don't have to fight her or feel guilty when she spits out another treat. It's a small thing but it feels like I'm finally doing right by her.

Okay so I was one of those people who thought "her food says complete and balanced, she's fine." Then Cled started getting these awful gunky eyes and sneezing fits every few weeks. Vet said probably herpes, recommended lysine.I tried three different treats - she wouldn't eat ANY of them. Found these drops in a Facebook group and figured why not. t's been about a month and I haven't seen the gunk come back. Maybe it's coincidence but I'm not stopping now.

I've spent SO much money on lysine treats that ended up in the trash. Maisie would sniff them and walk away. Every single brand. Meanwhile she's sneezing and her eyes are running and l'm just standing there feeling like the worst cat mom. The drops were kind of a last resort honestly. She doesn't even know they're in her food. Three weeks in and her eyes are clear for the first time in months.I could cry.

Milo's 9 and he's had the herpes thing basically forever. I'd just accepted the sneezing and eye crusties as "normal for him" which sounds awful now that I'm typing it. Someone in my cat group mentioned these drops and I almost didn't try them because l've been burned before. But he's like a different cat?? More energy, eyes are actually clear, hasn't had a sneezing fit in weeks.I don't know why I waited so long.

Questions? We've got answers!
My cat won't eat lysine treats or gels. Will she actually take this?
My cat won't eat lysine treats or gels. Will she actually take this?
This is exactly why we made it a liquid. PurrVita L-Lysine Drops are tasteless and disappear completely into wet food, dr food, raw, or even water. Most cats don't even notice it's there. No more fighting, no more spit-out treats, no more wasted money.
My cat has had herpes for years. Is it too late to start?
My cat has had herpes for years. Is it too late to start?
It's never too late. FHV-1 is a lifelong virus - it doesn't go away, but consistent immune support can help reduce how often flare-ups happen and how severe they get. Many of our customers have senior cats who saw real improvement within a few weeks.
I've tried lysine before and it didn't seem to help. Why would this be different?
I've tried lysine before and it didn't seem to help. Why would this be different?
Most lysine products fail at step one: getting inside your cat consistently. If your cat refused the treats, spit out the gel, or only ate it sometimes - they never got steady support. Our drops actually get in, every single day. That's when lysine can do its job.
How soon willI notice a difference?
How soon willI notice a difference?
Every cat is different, but most customers report less sneezing and clearer eyes within 2-3 weeks of daily use. For cats with frequent flare-ups, the real win is what doesn't happen - fewer trips to the vet, fewer nights of worry.
Can I give too much? Is it safe every day?
Can I give too much? Is it safe every day?
L-Lysine is an amino acid, not a drug. It's very safe and well-tolerated - any excess is simply excreted naturally. That said, we include a precision dropper so you can give the right amount every time without guessing.
My cat's herpes seems under control right now. Does she still need this?
My cat's herpes seems under control right now. Does she still need this?
That's actually the best time to use it. Herpes doesn't disappear - it hides and waits for stress to reactivate it. Consistent daily support helps keep your cat's immune system ready, so you're not caught off guard by the next flare-up.
How do I know this product is safe and actually works?
How do I know this product is safe and actually works?
PurrVita L-Lysine is pharmaceutical-grade and third-party tested for purity. But honestly? The real proof is in the thousands of cat parents who finally stopped dreading flare-up season. We also back every bottle with a 60-day money-back guarantee - if it doesn't work for your cat, you pay nothing.
