    “Finally understood why the label wasn’t enough”

    I always bought the expensive stuff. But when I learned heat processing wipes out most of the taurine and they just spray a minimum back on I started thinking about what Mochi actually gets every day. She’s never caught prey in her life. Tried Yeyko and within a month she was jumping onto the counter again, coat shinier than it had been in years.

    “Took me a while, but now it’s just part of our routine”

    I kept putting it off wasn’t sure if extra taurine was even safe. Turns out it’s water-soluble, so any excess just flushes out. Once I thought about the fact that Oliver has never once eaten raw prey the way a cat in the wild would, adding Yeyko made total sense. Five seconds on his food. Done.

    “Didn’t need a problem to start doing the right thing”

    I thought regulated food covered everything. But taurine gets cooked off during processing, and cats can’t store it so the gap reopens every single day. Biscuit’s 11 and eats grain-free, which I thought was the gold standard. Yeyko just closes the loop. I know she’s getting what her body was built to run on.

    “She’s Just More Like Herself Again”

    “Mochi stopped jumping on the bed in the mornings. She wasn’t sick, the vet said she was fine, but something felt off. I started adding a scoop of Yeyko to her kibble and honestly didn’t expect much. Three weeks later she was back at the door every morning. I don’t know how to explain it but she just seems more like herself.”

    “Finally One She’ll Actually Eat”

    “I kept seeing stuff about what cats were actually built to eat and went down a rabbit hole. Tried a few supplements, most of them smelled weird and she wouldn’t touch her food. Yeyko just… disappears into the bowl. She has no idea it’s there. Been doing it three months now and I’m not stopping.”

    “One Ingredient. That’s It. Sold.”

    “I’m not someone who buys a lot of pet supplements. One ingredient, lab tested, and you just scoop it in. That’s all I needed to hear. If it didn’t work I had 60 days to get my money back anyway. It worked.”

What taurine does inside

Taurine is an amino acid your cat can’t make enough of on their own. It has to come from food every single day.

  • Heart — packed into heart muscle, part of how it works daily
  • Eyes — found in high amounts in the retina
  • Muscles — in tissue from shoulders to paws
  • Digestion — helps make bile salts that break down fat

A wild cat got it from every kill. An indoor cat gets it from a bowl. That’s the gap one scoop fills.

Frequently Asked Questions

What does taurine do for my cat?

Taurine is an amino acid. Cats can’t make enough of it, so it has to come from food. It’s part of how a cat’s heart, eyes, muscles and digestion do their daily work. It’s a nutrient, not a medicine.

My cat seems healthy. Do I need to add this?

Not every cat does, and it’s not an emergency. This is for owners who want to give an indoor hunter a bit more of what the hunt used to give. If that’s you, it takes ten seconds a day. If it’s not right for her, you have 60 days to decide.

My cat has a health condition, like kidney or heart disease. Can she have this?

Ask your vet first. Cats with a diagnosed condition often have a diet plan already. Aladdas Taurine is a nutrient, and we don’t say it helps or treats any condition. Show your vet the label and ask.

My cat vomits a lot. Will this stop it?

We can’t say that. Frequent vomiting has many causes, and it’s worth a vet visit. Aladdas Taurine is a daily nutrition scoop, not a fix for vomiting.

How often should I give it?

One scoop a day, mixed into her food. Use the dosing chart for her weight. Daily is the point: she needs a fresh supply each day, so a steady routine works better than a scoop now and then.

Is it safe?

aurine is a nutrient cats need, and it’s already added to complete cat foods. Follow the dosing chart. If your cat is pregnant, nursing, a kitten, or on a vet-prescribed diet, check with your vet first.

What if my cat won’t eat it?

It’s unflavoured, so most cats don’t notice it. If she’s fussy, start with a small pinch for two or three days, then build up. A spoonful of tuna water or warm broth stirred in can help. Still no luck? Email us. You have 60 days.

Maybe not. Fresh whole prey, heart included, is the gold standard. If you feed a complete raw or premium diet, ask your vet if she needs more. Yeyko Taurine is for owners who want to add a daily top-up.

Can I give too much?

Taurine is water-soluble, and cats generally tolerate it well. More isn’t better, though. Stick to the chart.

How is this different from the taurine in her food?

It’s the same amino acid. A wild cat got it from whole prey, muscle and heart included. Most cat food is made to meet a legal minimum, and many makers add taurine back after cooking. Yeyko Taurine is a simple way to add a little more, in a scoop you control. It goes on top of her food. It doesn’t replace it.
