If Your Cat's Eyes Are Watery or the Sneezing Won't Stop, It's Probably Not What You Think.
For the past few weeks, I have tried every supplement, every eye drop, every vet recommendation to help my cat Tomato with his constant watery eyes and sneezing.
Every time I thought we were making progress, the symptoms came right back. Not because I wasn't trying hard enough. Because nothing I gave him was actually fighting the real problem.
Hi I'm Rachel,
August 2nd, 2025…
That's when I found this cat lost in the road
When I went to him
He climbed right up my leg and wrapped his paws around my neck
I knocked on some doors to see if he belonged to anyone and nobody answered…
It was raining and I couldn't get myself to leave this baby on the road so I decided to keep him…
Although I was never really a cat person, we immediately bonded.
He likes to cuddle during the day, and I've learned all his body language.
He's always chatting with me and follows me around the house.
For the first year he seemed alright
But a few weeks ago, I started noticing his eyes looking watery and some sneezing here and there
I didn't think much of it
"It's probably some 'cold' or allergy that will go on its own after a couple of days" - I thought
I kept an eye on him
Some days went by...
But he didn't seem to be getting better!
If anything the sneezing got a little bit worse and his eyes still looked like he wants to cry all the time
By then I was getting really worried and I felt terrible because I didn't know how to help
I just felt like a bad mom
Okay Tomato, let's take you to the vet…
$700 later and some antibiotics and eye drops
For the first 4 days after the vet visit Tomato was actually looking slightly better, not completely himself but better
A week later?
We're back at step 0
Same runny nose and watery eyes
He even started doing this thing where he was squinting his left eye
I couldn't just sit and watch hoping he gets better
But I also didn't want to waste more money at the vet's office just to get brushed off again with some eye drops
I decided to look deeper into it
What started as a quick google search…
Turned into hours of scrolling through reddit posts, TikTok videos and random articles
One article in particular really caught my attention
A vet from Europe explained the root cause behind his symptoms in a way that finally made sense
It also explained why none of the stuff we tried actually worked…
He basically wrote:
The key to your cat's watery eyes and sneezing have nothing to do with their eyes or nose….
And everything to do with their immune system
After 20 years of experience, and dealing with thousands of cats every month I noticed one pattern across all cats I have come across with runny nose and eyes
The real problem is usually a virus called Feline Herpesvirus‑1 that hides deep inside their nervous system for life.
Over 90% of cats in the US have it
Most cats catch this virus when they're kittens. (usually from shelters, a pet store, or in rare cases from a short visit to a vet clinic where an infected cat was present)
The virus hides in their body forever.
When your cat gets stressed or their immune system gets weak the virus wakes up and makes them sneeze or get watery eyes or discharge again.
Your cat isn't catching it over and over. They already have it. It's just waking up.
Usually it's not a big deal and cats manage to keep it under control
It just gets worse when their immune system is too weak to control it
Here's where it gets tricky…
Without supporting their immune system when it's weak
What starts as a light 'cold' or a 'watery eye' could end up developing into serious issues like rhinitis, conjunctivitis or even Pneumonia
In real life this looks like this:
they stop playing or moving much
they start eating less
Their eyes look squinty or even swollen
Some cats lose their eye and require expensive surgeries
The good news?
If you catch it early, and you start helping them if you noticed any symptom it doesn't have to go that way
If anything I see cats with herpes virus all the time living a happy long life while keeping this virus under control 'asleep'
Just because their owners helped them by maintaining a low stress, safe environment and a strong immune system.
When I read that article, it hit me like a truck
HERPES??
Why didn't my vet mention any of this earlier?
I looked at Tomato and it all started clicking
I was indeed noticing some of the symptoms he mentioned, and Tomato wasn't really looking like himself lately
Suddenly all of the
✗ eye drops
✗ l-lysine supplements
✗ antibiotics
Made sense why they were not doing enough
We were trying to fix the symptoms instead of fixing the actual problem
( a weak immune system )
I spiraled deeper in the rabbit hole for ways to boost his immune system
Most of what I found was junk
✗ Generic cat multivitamins that barely did a thing
✗ L-Lysine supplements that's not enough on its own
✗ DIY solutions that did more harm than good
Until someone in a reddit group mentioned PrimalCat
"Eye and Immune Support Chews"
Apparently they were the only ones that kept coming up in every thread I read
When I checked the label I wasn't expecting much
But this had things I'd never even seen in a cat supplement before
I recognized a few things right away
L-Lysine — I already knew about this one, most cat owners do. But on its own it was never enough
Probiotics — made sense, I've heard gut health affects the immune system
But then there were ingredients I had never even seen in a cat supplement before
Colostrum — apparently it's packed with natural antibodies
Beta-glucan — helps train the immune system to actually respond
Lactoferrin — fights viruses and bad bacteria naturally
And then stuff for his eyes specifically
Taurine, Omega-3, Lutein
I didn't even know half of these existed for cats
It felt like everything I would've had to buy separately all in one chew
Also the comments from people who tried it before really convinced me
At this point I would just do anything to see him feeling healthy and like himself again
And honestly I'd already spent more on one vet visit than this costs for three months
So I figured I will give it a try…
1 day after it arrived, I opened the tub and I gave 1 chew to Tomato
I was honestly worried because he's really picky about what he eats
However he didn't seem to have an issue with it, he ate right off my hand
So here's the progress I saw with Tomato after putting him on these for a couple of weeks:
The sneezing slowed down. Not gone, but I wasn't hearing it every few minutes anymore. His eyes still looked watery but something about him just felt a little different. Like he had more energy in the morning.
This was the moment I knew something was working. I woke up, looked at him, and his eyes were clear. No gunk, no watery look. I honestly just sat there staring at him for a minute. The sneezing was maybe once or twice a day instead of constant.
I realized I hadn't wiped his face in over a week. He was playing again, actually running around the house like he used to before all of this started. That left eye that was always squinting? Wide open. I kept waiting for it to come back. It didn't.
Things just feel normal now. His coat looks great, he's eating well, and I'm not constantly checking his eyes every morning. We haven't been back to the vet since.
Whatever this stuff does, I want it to keep doing it because we haven't visited the vet since then and Tomato seems to be healthier than ever
I still give it to him as a preventive measure, and honestly because it gives him a really nice coat
But this one comes with a 60-day money back guarantee
Give it a try. If Tomato can get better after everything we went through, I think your cat can too.
But don't just take my word for it:
I am not saying don't go to the vet
I am saying I spent over $700 "managing" symptoms before anyone told me the real issue was his immune system
Here's what that looked like:
If someone had told me sooner that the real problem was his immune system I could've skipped half of this list
Look I'm not going to sit here and tell you this cured him
He still sneezes once in a while
And on stressful days I can tell his eyes get a little watery
But it's not the same
Before it felt like we were losing
Now it feels like he's actually fighting it off
That's all I wanted
And honestly if it doesn't work for your cat they give you your money back within 60 days
So either your cat starts getting better
Or you get a full refund and you're no worse off than right now
I just wish someone had told me about this before I spent $1,400 learning the hard way
and 10,000+ cat parents made the switch
