I honestly thought this was unnecessary because my vet said my cat's symptoms were "just allergies." But after learning that parasites can cause chronic gut inflammation — and that most vets don't even test for them — I decided to try FelisLabs. Within three weeks, my 7-year-old tabby had stopped vomiting and was sleeping through the night.

I hesitated for weeks because I'd never heard of giving my cat herbs I didn't recognize. My holistic vet explained that the probiotic rebuilds what chemical dewormers destroy. FelisLabs even includes clear dosing instructions and a dropper. Now it's part of my daily routine, and I finally feel at peace knowing she's protected.

I was convinced parasites were something that only happened to outdoor cats. My integrative vet explained that Cornell puts feline GI parasite prevalence at up to 45% — and that standard fecal tests miss up to 50% of Giardia cases. Even indoor cats carry subclinical loads their vet isn't catching. I started FelisLabs the next week and the peace of mind alone has been worth it.
World's First Cat-Safe Formula
Built for cats — not adapted from dogs.
For years, cat owners were told "nothing exists for us." That's because most parasite-fighting botanicals sitting in every dog dewormer are actively toxic to cats. FelisLabs is the first cat-safe alternative — engineered from scratch by feline vets, never repurposed from a dog formula.
The hidden parasite load robbing your cat of their health.
Most cat owners are shocked to learn their cat probably has parasites right now — not the visible worms kind, but the subclinical kind. Low-grade infections that don't show on standard fecal tests but quietly damage the gut every day.
Fecal tests miss up to 50% of Giardia cases. 30–50% of subclinically infected cats test negative — and most vets aren't taught to look beyond the test.
Here's what parasites actually cause in cats:
Chronic vomiting — dismissed as "sensitive stomach"
Obsessive grooming and bald patches — blamed on allergies
Nighttime restlessness and 3AM yowling — written off as anxiety
Litter box accidents — dismissed as behavioral
Skin and coat problems — medicated when it's gut inflammation
Weight loss despite eating — blamed on aging
The FelisLabs Difference
Medications suppress. FelisLabs rebuilds.
Your cat's gut is the foundation of their entire immune system — and 90% of their serotonin is made there. When compromised, everything downstream breaks.
Cerenia and prednisolone suppress the vomiting reflex and inflammation. They don't fix the gut.
Chemical dewormers kill adult worms. They don't rebuild the environment that let parasites colonize in the first place.
FelisLabs gives your cat's gut the tools to actually repair itself — 4 cat-safe botanicals, dual probiotics, and L-Glutamine gut-lining repair, in liquid form for direct absorption.
Supports natural parasite expulsion at every life stage
Rebuilds gut microbiome with dual veterinary-grade probiotics

We do gut health differently.
FelisLabs doesn't mask symptoms or push toxic herbs. It works from the inside out — by rebuilding the gut microbiome where chronic problems actually begin.

Real Results
Reviews that made us smile.
★★★★★
Mary R.
"She used to scoot across the carpet daily. Her coat was dull and patchy. Now her gut is healed — she even sleeps through the night for the first time in two years."
★★★★★
Sarah M.
"The vomiting never stopped. Every few weeks — more Cerenia, another prescription diet. Two months on FelisLabs, I realized she'd stopped throwing up. That was four months ago. Not one episode since."
★★★★★
Rebecca H.
"Bella's only 4, but she'd been on prednisolone for chronic 'IBD' since she was 2. Now — no more weekly vomiting, no bald spots on her belly, and her weight came back. Her vet approved tapering off completely."

This changed how I treat chronic symptoms
"After 14 years in feline medicine, this is the only formula I've seen that's safe for cats' unique liver metabolism AND actually rebuilds the gut damage parasites leave behind. I recommend it to every chronic-symptom cat owner I see."

The results surprised me
"I was skeptical. But the science on gut inflammation and subclinical parasite loads is solid. Skin improvements were visible within weeks in my toughest cases. The coat came back."

Frequently Asked Questions
Everything you need to know about FelisLabs Parasite Drops.
How long does it take to see results?
FelisLabs works in two phases simultaneously. Phase 1 — Within 7 days: Stools firm up, vomiting frequency drops, your cat seems calmer and less restless almost immediately. Phase 2 — Within 7–21 days: The dual probiotic blend restores gut integrity and rebalances the microbiome — where deeper, lasting change happens. Reduced grooming, fewer litter box issues, deeper sleep.
Is FelisLabs safe for daily use?
Yes. All 7 ingredients are natural and dual veterinary-grade probiotics, manufactured in a GMP-certified facility and third-party lab tested. We specifically excluded wormwood, black walnut, clove, and oregano oil — cats cannot safely metabolize these, yet they appear in most competitor products.
Will my cat throw it up?
Very unlikely. FelisLabs is fish-flavored liquid drops added to wet food — most cats don't even notice it. If your cat is currently vomiting from gut inflammation, the cleanse addresses the driver, so vomiting typically decreases within 2–3 weeks. In rare cases where a cat has a sensitive stomach during the first few days, halve the dose for the first week and gradually increase.
What makes FelisLabs different from other cat dewormers?
Three things: (1) It's cat-safe — no wormwood, no black walnut, no toxic herbs. (2) It includes a dual probiotic blend that rebuilds the gut microbiome — most dewormers just kill worms and leave the gut damaged. (3) It's liquid drops with 98% absorption, not poorly-absorbed chews.
What if my cat is currently on prescription medication like prednisolone or Cerenia?
FelisLabs is safe to use alongside most prescription medications, but always coordinate with your vet before making any changes. Do NOT stop prednisolone or other prescription medications abruptly — this can cause serious withdrawal reactions. Start FelisLabs alongside her current treatment, give it 3–4 weeks, and if you see improvement, schedule a call with your vet about a supervised taper.
Can I use FelisLabs alongside food, supplements, or medications?
Most owners use FelisLabs alongside existing food and supplements without issue. Because this protocol addresses the gut environment, some cats may naturally need less of their current prescriptions over time. Always coordinate with your vet before adjusting medications.
How do I know the right amount to give my cat?
Dosing is based on your cat's weight. Small cats (under 8 lbs): 0.25 ml / ~5 drops daily. Medium cats (8–15 lbs): 0.5 ml / ~10 drops daily. Large cats (15+ lbs): 0.75 ml / ~15 drops daily. Add directly to wet food once per day.
