SLEEK Pro Hair Straightener
“I didn’t realize how important taurine was until I started paying attention to the litter box. After adding these drops to my cat’s food daily, I feel so much more confident about her long-term health. It’s easy to use, no mess, and she doesn’t even notice it’s there. This is now part of our routine."
Cats are one of the only mammals that cannot produce taurine on their own. They depend entirely on food to get it every single day. The problem is that the heat processing used to manufacture commercial kibble — even premium, grain-free, and vet-recommended brands — destroys up to 70% of taurine before it ever reaches your cat's bowl.
Feline Vitals delivers 500mg of pharmaceutical-grade L-Taurine in liquid form, directly into your cat's wet food. Liquid absorbs faster than powder and is completely undetectable — no taste, no smell, no texture change. Your cat gets the taurine their body has been missing, every single day.
Sleeping more than usual. Dull or rough coat no matter what food you try. Stopped jumping, stopped playing, stopped greeting you at the door. Eyes that look hazy or less present. Disengagement from things they used to love.
Most owners are told their cat is "just aging." In the majority of cases it isn't aging — it's a fixable deficiency that has been building silently for months.
Most owners notice the first changes between days 5 and 8 — increased alertness, eyes tracking movement again, more engagement. Coat improvements typically show between weeks 2 and 3. Full transformation — energy, playfulness, greeting behaviour returning — usually within 30 days.
Results vary depending on how long the deficiency has been building, but the 30-day guarantee means you have nothing to lose.
Cats are obligate carnivores with hypersensitive palates. Powder changes the texture and smell of food — most cats detect it immediately and walk away from the bowl.
Liquid disappears completely into wet food. No texture change, no smell, nothing for your cat to detect or reject. One dropper. Once a day. That's it.
Yes. Taurine is not a medication — it is a nutrient your cat's body is already supposed to be getting from food. Feline Vitals contains pharmaceutical-grade L-Taurine and nothing else. No fillers, no additives, no artificial ingredients.
Every batch is third-party tested in the USA. Safe for daily long-term use in cats of all ages and breeds.
Orders are processed and dispatched within 1–3 business days. Once your order has shipped, a tracking number will be sent to your email within 2–3 days — please allow a little time for tracking information to update after you receive it.
If you have any questions about your order, reach out to our support team and we'll get back to you promptly.
If you don't see a measurable difference in your cat's energy, coat, or engagement within 30 days, we will refund you in full. No questions, no hoops, no return required.
We offer this because we know what taurine deficiency looks like — and we know what happens when it's corrected. The only risk is waiting.

4.9 from 2,400+ cat parents
"My Sphynx Nala was always sluggish and her skin looked dull. After 2 weeks of Feline Vitals her energy is through the roof and her skin feels so much smoother. The drops are SO easy — she doesn't even notice them in her food."
"My vet said Whiskers needed taurine supplements but he HATED the powder — would refuse to eat his food entirely. Switched to these drops and he has no idea they're there. His coat is shinier than it's been in years. He's 14 and acting like a kitten again."
"I did a ton of research before buying and this was the only liquid taurine I could find that wasn't loaded with fillers. Takes me literally 3 seconds every morning. Milo's eyes look clearer and he's way more playful. Already ordered a second bottle."
Why Taurine Is the One Nutrient You Can't Afford to Overlook
This isn't a trendy supplement. It's the single amino acid your cat's heart, vision, and immune system depend on every day — and the one she physically cannot produce on her own.

Fact 01
Cats Cannot Produce Taurine. At All.
Unlike dogs, humans, and most other mammals, cats lack sufficient activity of the enzyme required to synthesize taurine from other amino acids. Every milligram of taurine in your cat's body has to come from her diet. Not some of it. All of it. This is documented veterinary consensus — not a supplement brand's marketing claim.
↳ Morris et al., UC Davis, 1994 · VCA Animal HospitalsFact 02
Processing Depletes the Taurine in Her Food.
Taurine is water-soluble and heat-sensitive. The same high-temperature processing that gives kibble its shelf life significantly depletes naturally occurring taurine — which is exactly why manufacturers add it back synthetically after production. AAFCO requires twice as much taurine in canned food as dry food to compensate for what retort sterilization destroys. "Added taurine" on a label means the original didn't survive.
↳ AAFCO Nutrient Profiles · IQI Pet Food White Paper, 2021Fact 03
Deficiency Is Silent for Months Before It's Visible.
Taurine deficiency doesn't announce itself. It accumulates quietly — plasma taurine can drop to near-zero within weeks while your cat looks completely normal. By the time clinical signs appear, damage to the retina or heart muscle may already be irreversible. Early supplementation is the only intervention that works.
↳ Knopf et al., Journal of Nutrition, 1978 · VCA Animal HospitalsFact 04
The Heart Holds More Taurine Than Almost Any Other Tissue.
Taurine concentrates in the heart muscle at roughly 100 times its plasma concentration. In 1987, UC Davis researchers published a landmark study in Science showing low taurine directly caused dilated cardiomyopathy in cats — and that supplementation reversed it. Before this, DCM was the most common heart disease in cats. Daily taurine is what keeps it that way.
↳ Pion et al., Science, 1987 · VCA Animal HospitalsFact 05
You Cannot Over-Supplement Taurine. The Safety Profile Is Ironclad.
Unlike fat-soluble vitamins which accumulate in tissue, taurine is water-soluble. Your cat's body uses what it needs and excretes the rest. There are no documented cases of taurine toxicity in cats. VCA Animal Hospitals states: "Supplementation is relatively safe, with no reports of problems associated with excessive dietary taurine in the cat." Zero downside risk.

Taurine: The One Nutrient
Your Cat Can't Live Without
Unlike most animals, cats can't produce taurine on their own.
It has to come from their diet — every single day.
Eye Health
Taurine supports healthy retinas and sharp, clear vision
Heart Health
Essential for normal heart muscle function and circulation
Energy & Vitality
Healthy taurine levels help cats stay active and playful
Coat & Skin

Why daily supplementation works
Taurine supports your cat's heart, eyes, and nervous system simultaneously. Because cats process and excrete it quickly, consistent daily intake matters more than occasional high doses — which is exactly why a simple daily drop routine is the most effective way to keep levels topped up.
One drop a day is all it takes to keep your cat's taurine levels where they need to be.
Most owners notice a difference in coat and energy within a few weeks.
Three Steps. Thirty Seconds. Done.
No pill pockets. No powder clouds. No battle at the bowl. Just a daily habit so simple you'll wonder why you waited.
Fill the Dropper
Squeeze the bulb, draw up the right amount for your cat's weight. Takes about five seconds. The dose guide below makes it impossible to get wrong.
Add to their Food or Water
Drop it directly into wet food, dry food, or their water bowl. Tasteless and odorless — she won't know it's there. No texture change. No rejected bowl. No negotiation.
She Eats. You Rest Easy.
That's it. One daily drop and you've covered the one essential nutrient their body can't produce on its own. No guesswork. No guilt. Just the quiet confidence of knowing you did it.
| Cat Weight | Daily Dose |
|---|---|
| Small Cat 2–4 lbs · 1–2 kg | 0.5 mL half dropper |
| Average Cat 4–11 lbs · 2–5 kg | 1 mL 1 full dropper |

Everything You Need to Know
Still have questions? We've got answers.
Is this safe for my cat?
Absolutely. Taurine is an essential amino acid that cats need every single day — it's not a drug or a stimulant. Our formula is vet-formulated, lab-tested, and made in a GMP certified facility. Safe for cats of all ages and breeds. If your cat has an existing medical condition, we recommend checking with your vet first.
Will my picky cat actually eat this?
Yes — that's the whole point of drops. Unlike powders that clump and change the texture of food, our liquid drops are tasteless, odorless, and mix invisibly into wet or dry food. 98% of cats accept it on the first try with zero transition period. Your cat won't even know it's there.
How long until I see results?
Most owners notice visible coat improvement within 2–3 weeks and increased energy within the first 10 days. Heart and vision benefits build over time with consistent daily use. The full transformation typically happens around the 30-day mark — which is exactly why we offer a 90-day guarantee. We want you to see it for yourself.
Is it safe for kittens and senior cats?
Yes to both. Kittens 6 months and older can use our standard dosing. For senior cats, taurine supplementation is especially important as natural absorption decreases with age. Many of our best results come from senior cat owners who noticed their cat "acting years younger" within weeks.
Doesn't cat food already have taurine?
It should — but here's the problem. Taurine degrades during processing. Heat, storage, and manufacturing all reduce taurine content. By the time it reaches your cat's bowl, the actual bioavailable taurine can be 40–60% lower than what's on the label. That's why vets increasingly recommend supplementation, especially for indoor cats.
How do I use it? What's the dosage?
One full dropper per day. Squeeze, drop into food or water, done — takes about 3 seconds. Works with wet food, dry food, or directly into their water bowl. One bottle = 60-day supply. Use it at the same time each day for best results, but missing a day won't reset progress.
What if it doesn't work for my cat?
Then you pay nothing. We offer a 90-day money-back guarantee — no questions asked. Keep the bottle. No return shipping. No hoops to jump through. We're that confident because the science behind taurine supplementation isn't new — it's just that nobody made it this easy before.
Can I use this with other supplements?
Yes. Feline Vitals Taurine Drops are safe alongside omega-3s, probiotics, joint supplements, flea/tick prevention, and prescription diets. Taurine is a naturally occurring amino acid — it doesn't interact with other supplements. If your cat is on immunosuppressants or chemotherapy, check with your vet first.
Still not sure? Try it risk-free for 90 days.
If your cat doesn't transform, you get every penny back. Keep the bottle.
