Why Immune Flare-Ups Keep Catching Cat Parents Off Guard
Many cats carry common viral stressors for life. Most of the time, everything looks fine — until something shifts. A change in routine. Seasonal stress. A vet visit. And suddenly your cat isn’t quite as comfortable as usual.
Sneezing returns. Eyes look irritated. Breathing seems heavier.
Not dramatic enough to panic — but enough to worry.
If you’ve tried L-Lysine before, you’re not alone. Treats, gels, powders… most cat parents have been there. The problem isn’t the ingredient — it’s consistency.
Some formulas are refused.
Others upset sensitive stomachs.
And many never become part of a daily routine.
No consistency means no real support over time.
Why We Created Primalis L-Lysine
Primalis L-Lysine was designed to make daily immune support simple, gentle, and easy to stick with — so cat parents don’t have to second-guess their routine.
🧬 Daily L-Lysine Support Can Help:
🛡️ Support Immune Balance

I got this for a stray kitten who was sneezing a lot. I started purchasing L-Lysine for my cat at the at the suggestion of my vet.
He’s been more comfortable overall, even though he still has good days and bad days.
What I appreciate is that he eats it easily and it fits my budget, so I can stay consistent. I’m hopeful with continued use.

We took in a former feral cat a few years ago, and recently she started showing signs of discomfort — coughing, watery eyes, and a runny nose. Since she’s impossible to take to the vet, I did some research and decided to try this as part of her routine. After a few days mixed into wet food, she seemed much more comfortable and back to her normal self. I’ve kept it in her food ever since, and she’s back to playing and running around the house.

L-Lysine is fantastic for my cats’ daily routine. It helps support their immune balance, and when we stay consistent, they seem much more comfortable overall. I mix it with their food and they actually like the taste, which really helps on picky days. I’ve tried a few different brands, and this one has been my favorite so far — I’m already on my third jar.

My cat has no problem eating this, which was my biggest concern. The included scoop makes it easy to give the right amount, and she actually prefers this over another brand we tried. It’s only been a few days, so I’m not expecting anything dramatic yet, but since our vet recommended L-Lysine as part of her routine, I’m happy to keep using it.

Support your cat’s daily comfort — with one simple daily scoop.
Cats don’t always show warning signs before flare-ups start.
Most of the time, everything looks fine — until it isn’t.
Sneezing comes back.
Eyes start acting up again.
Breathing feels a little heavier.
And for many cat parents, the hardest part is that it comes and goes.
Good days. Bad days. Relief… then another flare-up.
Even high-quality food isn’t designed to help manage recurring flare-ups long term. Over time, that lack of consistent support can make it feel like you’re always reacting instead of staying ahead.
Primalis L-Lysine was created for cat parents who want consistency — not guesswork.
With one simple daily scoop, you’re supporting your cat’s immune system in a way that helps reduce the ups and downs, so flare-ups feel less frequent and less disruptive over time.
Because flare-ups don’t usually come with a warning.
They build quietly — then show up again.
Daily support isn’t about fixing something overnight.
It’s about helping your cat stay more comfortable, more often — and giving you peace of mind knowing you’re doing something early and consistently.
Peace of Mind for Every Cat Parent
If flare-ups keep coming back:
Support consistency, so it’s not just good days and bad days.
If your cat seems “fine” today:
That’s often how flare-ups start — quietly, then they show up again.
If you’ve tried L-Lysine before:
The issue usually isn’t the ingredient — it’s staying consistent.
If you don’t want to wait for sneezing, eyes acting up, or breathing changes:
Daily support helps you stay ahead, not react.
If you care deeply (and you do):
Choosing simple, daily immune support is one of the most responsible things you can do —
for your cat, and for your own peace of mind.
Questions ? We've got answers!
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?
Not at all. Many cat parents start using L-Lysine after years of recurring flare-ups.
This isn’t about curing anything overnight — it’s about supporting consistency. Even cats who’ve dealt with herpes for a long time can benefit from daily immune support that helps reduce the ups and downs over time.
Can I give too much? Is it safe every day?

Primalis L-Lysine is designed for daily use as part of a consistent routine.
Always follow the serving guidelines on the label, and if your cat has specific medical conditions, it’s a good idea to check with your veterinarian — especially if lysine was suggested as part of their care plan.
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?
This is one of the most common experiences we hear.
In most cases, the issue isn’t lysine itself — it’s consistency.
Many treats, gels, or powders get refused, spit out, or used irregularly. When support comes and goes, flare-ups tend to come back too.
Primalis is designed to be easy to give every single day, so immune support isn’t hit-or-miss.
How soon should I expect to notice a difference?
How soon should I expect to notice a difference?
Every cat is different. Some cat parents notice subtle changes within a few weeks, while others see more gradual improvements over time.
What most people notice first isn’t a dramatic change — it’s fewer bad days, smoother routines, and flare-ups that feel less frequent or less disruptive when they do happen.
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 when many cat parents choose to stay consistent.
Herpes flare-ups often come and go. When everything looks “fine,” daily support helps maintain immune balance so you’re not starting from scratch when things act up again. It’s about maintaining stability, not reacting after the fact.
My cat is picky — will he even eat it?
My cat is picky — will he even eat it?
Primalis L-Lysine is designed to be easy to mix into food and generally well accepted.
Most cats don’t notice it when added to their regular meals.
If your cat is especially sensitive, starting with a smaller amount and gradually increasing often helps.
What if I don’t see an improvement?
