Frequently Asked Questions

Common and normal are not the same thing. Cats vomit daily because bile accumulates in an empty stomach overnight — and bile only accumulates when there isn't enough taurine to conjugate it properly. Your vet sees it constantly, so it starts to feel like a baseline. It isn't. It's a nutritional gap with a direct fix.
Kibble is extruded at 120–200°C. At that temperature, the Maillard reaction chemically bonds taurine to carbohydrates — and once bound, it cannot be absorbed. Research shows cats on extruded diets retain 25–50% less taurine than cats on unprocessed food. The taurine on the label went in. It doesn't come out the same way. PureFelis is added cold, after cooking — fully intact, fully absorbed.
Most taurine powders on the market are 20–80% maltodextrin — a cheap sugar filler that dilutes every dose. You weren't necessarily getting what the label said. PureFelis is a single ingredient: 100% pharmaceutical-grade taurine, third-party tested, no fillers. If the last supplement didn't work, dose dilution is almost certainly why.
Most customers see the first clean morning within 7–14 days. Some see it in 3–5. Cats with deeper long-term depletion can take up to 3 weeks. If you reach 60 days and see no change, we refund you completely — no return required, no questions asked.
Cats reject food based on smell. They have roughly 200 million olfactory receptors and use scent as their primary food filter. PureFelis is completely odorless and tasteless — it dissolves in seconds in wet or dry food with no change in smell or texture. Even the most food-averse cats accept it without incident.
Taurine is essential — your cat's body cannot make it and cannot survive without it. It's also water-soluble, so any excess above what the body uses is simply excreted. There is no known toxic ceiling in felines. The real risk isn't daily supplementation. It's daily depletion without replacing what's lost.

Taurine
I have six cats. One of them was vomiting daily, one pulling out her hair. I'd read about taurine and thought why not try it. I did. No more daily vomiting, the patches are gone, the coats are thicker and fuller. Eyes are brighter and more alert. Thank you for making my cats healthier and happier!

My cat would throw up every day
My cat would throw up once, twice a day. For years. I was worried about him getting enough nutrition. After 3 weeks of consistently giving him PureFelis, the vomiting is almost non-existent. I'm confident with continued use it will be a thing of the past. Love that it's delivered right to my house and ordering is so easy.

Outstanding product and company
Not only does Sasha look better and appear in excellent health, I recently had a problem with a shipment of her supplement and the customer service team worked with me to get it resolved. They showed compassion and understanding. Great staff and great product — worth every cent for your furbaby.

Your kitties will be happy you did
I'd been reading that cooking cat food destroys most of the taurine. I was sceptical, but decided to give PureFelis a try as a preventative. I have to say WOW — we noticed a difference quickly. We have two boys and both have more energy, brighter eyes, softer fur, and no one has vomited since we started. Fantastic product.

My cat is 18 years old
My cat is 18 years old and struggles with upper respiratory issues. I understand the role of taurine and giving her this supplement has relieved my worry of her going into kidney failure. Though her dose is low, she gets it every day and it helps her. I see a difference in her energy. So yeah, it works and I am grateful.

From Constant Hunger to Healthy Again
I recently adopted a 10-year-old cat who was incredibly lovable but constantly hungry. He would scarf down his food so fast that he'd throw it up shortly after eating. I searched everywhere, including Facebook, trying to figure out what could be causing it. PureFelis made such a big difference for him.

I was very sceptical at first
I was very sceptical, but it got great reviews so I thought I'd give it a try — for sure my 3 cats wouldn't eat it. To my surprise, all 3 of them ate it just fine. None of them turned away. One of my cats would only poop every 2 days. Now he poops every day. The vomiting stopped. I can believe this is something that has made a real difference.

Lethargic to Active
My 14 year old cat had become very lethargic, and her fur was changing texture. I ordered PureFelis. After about a week, I noticed she was a bit more perky. After about 3 weeks, I noticed her fur was becoming softer and smoother. I have been using it for about 3 months now and she is much more agile and active. Her fur is almost back to normal.

Service was quick and efficient
Service was quick and efficient. I mix the supplement into my cat's daily morning meal. His overall health is great — his fur looks great. Only minor thing is the scoop is a bit awkward to level off cleanly, but that's a small complaint. I believe in giving my cat the food and supplements to keep him fit and healthy so he can live a full long life.

Finally sleeping through the night
My cat Biscuit had been waking me up at 5am every single morning for almost two years. I'd hear the heaving and just lie there dreading what I was going to find on the carpet. Three different vets told me it was just a sensitive stomach. My gut never accepted that. Found PureFelis after a late-night Reddit spiral and within 10 days the morning sessions had basically stopped. I didn't realize how much that 5am routine had been wiring my anxiety until it just stopped happening. Worth every single penny.

My vet told me it was hairballs. For four years.
I want to be gentle here because I still like my vet, but she was wrong about this. Mochi has been throwing up yellow foam on an empty stomach almost every morning since she was two. Bloodwork normal, X-rays normal. "Some cats just do this." I accepted it for FOUR YEARS. Then I started reading about taurine and bile conjugation and it clicked immediately. Three weeks on PureFelis. Zero morning vomiting. I actually cried the first morning I woke up and there was nothing to clean up.

Five days. Literally five days.
I was fully prepared to give this 6-8 weeks. By day five the morning foam had stopped completely. My cat Persephone has had bilious vomiting syndrome for three years. I'd tried a $90/month prescription GI diet she eventually went on hunger strike for. Mixed one scoop into her wet food and she didn't notice at all. No sniffing. No hesitation. Just ate. The vomiting stopped. I keep waiting for it to come back and it hasn't. This is the most effective thing I've ever put in her bowl and I've tried everything.

I was setting an alarm at 4am just to feed her small meals
This is what my life had become. 4am alarm, shuffle to the kitchen, tiny snack to make sure her stomach wasn't empty overnight. If I slept through it I'd find yellow bile on the hardwood by 6am. My own doctor asked if I was sleeping okay because I looked exhausted at a checkup. That's how bad it was. PureFelis stopped it within two weeks. I slept a full 8 hours last night without once thinking about the cat's stomach. If that sounds dramatic you haven't lived with this.

I found out I was giving my cat basically pure sugar
Did you know that most taurine supplements you can buy online are 80% maltodextrin? I had been buying one for months thinking I was helping Cleo and I was literally scooping sugar into her food. Found that out on a forum, did my research, found PureFelis. One ingredient, completely odorless — you can verify it yourself. She ate it without any issue and the morning vomiting stopped in about two and a half weeks. I am genuinely angry at how long I was buying the wrong thing.

Three cats. All three improving.
I have three cats ranging from 4 to 11 years old. Harriet, my oldest, was the chronic morning vomiter — every day without fail, yellow bile, for two years. I figured once I started researching taurine that all three were probably deficient since they eat the same kibble. Started all three on PureFelis three weeks ago. Harriet's morning vomiting has basically stopped. But the surprise was that the younger two have noticeably more energy and their coats are shinier. I wasn't expecting that. It's a permanent part of their routine now.

My 17-year-old cat is acting like she's 10 again
Luna is 17. She'd been throwing up yellow bile in the mornings for about two years and I had basically accepted it as aging. My vet said to just monitor it. I wasn't satisfied. Started her on PureFelis about a month ago and the morning vomiting has essentially stopped. But the bigger surprise was how much more active she is. She's back at her favorite window spot, grooming herself more, actually interacting at dinner. At 17 I wasn't expecting transformation — but I don't have another word for it.

Spent $640 at the vet. This was $40.
I'm not blaming my vet. But the math is the math. Blood panel, urinalysis, X-ray, follow-up visit — $640 to be told Oscar had a sensitive stomach and the vomiting was "just his normal." Bought PureFelis on a whim after reading about taurine and bile on a forum. He has not vomited in the morning once in three weeks. Not once. I'm a little angry it took this long to find but mostly I'm just relieved he's okay and I finally have an answer.

My picky cat didn't notice it. Not even a little.
My cat Duchess has rejected literally every supplement, pill, and special diet I've ever tried. She once went three days barely eating rather than touch a bowl with new food mixed in. I was terrified she'd do the same here. I mixed PureFelis into her regular Fancy Feast and she ate every single bite. Didn't sniff at it twice. The tasteless claim is completely real. And the morning vomiting stopped in about three weeks. I cannot believe something this simple worked after everything else failed her.

I trusted my gut over my vet and I was right
I want to say this as gently as I can — my vet told me three separate times that daily vomiting was within the normal range for cats. My gut told me otherwise every single time. Watching your cat hack up yellow foam every morning and then lie lethargic for the next hour does not feel normal. Found PureFelis, started it, vomiting stopped in about two weeks. The vindication of being right after years of being dismissed is very, very real.

Three years of yellow foam every morning. Done.
For almost three years, finding yellow bile on my hardwood floor was as routine as making coffee. I tried elevated feeders, slow feeders, grain-free food, limited ingredient diets, probiotics — nothing changed. Maple just kept vomiting every single morning. PureFelis stopped it in about 10 days. One scoop in her wet food each night. That's it. I keep waiting for it to come back and it doesn't. I think about all the years I spent cleaning up when this was the answer.

I had tried four other taurine supplements. This is the one that works.
For anyone who has "tried taurine before" — please read this. I tried four different supplements over 18 months. All had filler ingredients Simon either rejected or that made the vomiting worse. What makes PureFelis different is exactly what they say: no maltodextrin, no fillers, no smell. My cat genuinely cannot detect it in his food. The morning vomiting that had been daily for two years stopped within three weeks. I don't know if the others failed because of the fillers but this one works.

She's playing again. I didn't expect that.
My cat Violet stopped being playful about a year ago — I assumed it was age, she's 9. The morning vomiting had been getting worse for six months, almost daily. I started PureFelis targeting the vomiting. The vomiting has basically stopped. But what surprised me was that Violet started playing again. She's chasing things, jumping on things, doing the 3am zoomies I used to complain about. I had no idea the taurine deficiency was affecting her energy too. I was not expecting this but I am not complaining.

For whoever is doing desperate midnight Google searches right now
I'm writing this because I remember those searches and I want this to come up. Miso had been vomiting yellow foam every morning for 14 months. I was exhausted. Three vets, $900 in diagnostics, zero answers besides "some cats just do this." Found taurine research online, found PureFelis as the only 100% pure option I could find. Within two weeks the morning vomiting had essentially stopped. I'm writing this at 8am having slept through the whole night. If you are where I was: please try this.

Took three weeks but was completely worth the wait
I want to set realistic expectations because I almost gave up at week two. Winston took about three weeks before I saw a clear reduction in the morning vomiting. By the end of week three it had basically stopped, and by week four I couldn't remember the last morning I cleaned up yellow foam. His coat is noticeably softer too, which I wasn't expecting. I'm on autoship now. For context: we tried prescription diets, Cerenia, feeding schedule changes, and two specialist consultations before this. Nothing else touched it.

"Some cats just vomit" should be illegal to say
I heard it from two different vets over three years. Duchess vomited yellow foam every single morning and I was told it was normal. I refused to accept that. Found the taurine-bile conjugation explanation online — it made complete biological sense immediately. PureFelis was the only pure powder I found after checking labels on everything I could find. She has vomited once in the past month, during a period I ran out and missed three days. I reordered immediately. This is not optional in our house anymore.

My 14-year-old cat has her spark back
Gracie is 14 and I genuinely worried we were entering her final chapter. She'd been losing weight slowly, vomiting yellow bile in the mornings, and sleeping far more than usual. My vet ran every test and found nothing wrong. A friend told me about taurine deficiency and sent me to PureFelis. Six weeks in — the morning vomiting has stopped, she's eating with more enthusiasm, she gained a little weight back, and she's started sleeping in my lap again which she hadn't done in over a year. This exceeded every expectation I had.

Simple. Clean. Does exactly what it says.
My cat vomited yellow foam every morning for two years. Tried everything my vet suggested. Nothing worked. Found PureFelis, checked the ingredients — literally just taurine — and ordered. One scoop into his food each night. Three weeks later the vomiting stopped. His energy is better. His coat is better. My floors are clean. I'm sleeping through the night. He has never once sniffed at it suspiciously or refused his bowl. Simple product. Works exactly as described.
