Why we made this

A cat cannot make taurine on her own. She has to eat it, every single day, for her heart and her eyes to keep working the way they should. Cooking and storage strip it out of food, and nobody is checking whether what is left in the bowl is enough.

So we made the simplest thing we could: one ingredient, measured, tested after it is made rather than before, in a tub that lasts a month. No blend, no proprietary formula, nothing to take on faith.

"Every other tub I picked up had maltodextrin listed first. I'm not paying thirty dollars for sugar."

What is inside the tub

One ingredient, and nothing else. No fillers, no flavourings, no binders, no anti-caking agents. Each level scoop holds 250 mg of taurine, the amount most older cats are quietly short of.

Will your cat eat it?

Pure taurine has no taste and no smell. Stir one level scoop through wet food and it vanishes. There is no pill to hide, no pipette, no wrestling at the kitchen counter.

I honestly thought this was unnecessary because my cat's premium food says complete and balanced. But after learning that processing destroys taurine, I decided to try NinthLife. Within a month, my 11-year-old cat was more energetic and her coat looked shinier than it had in years. I realized the label wasn't telling the full story. I'm glad I didn't wait until there was a problem.

I hesitated for weeks because I was worried about giving my cat too much taurine. My vet explained it's water-soluble and any excess just gets flushed out, so it's completely safe. NinthLife even includes the perfect little scoop so I don't have to measure or guess. Now it's part of my nightly routine and I finally feel at peace knowing my cat is covered.

I was convinced taurine deficiency was something that only happened decades ago before pet food was regulated. Honestly, I thought supplementing was just marketing. But my vet explained that cooking and storage destroy taurine, even in complete foods. That terrified me because my cat was already on a grain-free diet. I started using NinthLife and the peace of mind alone has been worth it. Now I know for sure my cat isn't losing something essential.

What to expect

  1. Weeks 1–2

    Nothing visible. She eats her food as usual and the routine settles in.

  2. Weeks 3–6

    Most owners mention energy first — a jump she had stopped making, an evening she stays awake for.

  3. Weeks 7–12

    Coat and steadiness are what people write to us about at this point.

Is it safe? How much do I give?

One level scoop a day

250 mg of taurine, stirred into wet food, once daily for cats of any adult size.

Taurine is water-soluble

What a cat does not use, she passes. There is no store-up effect to manage.

Safe alongside most diets

Prescription food, kibble, raw, or wet — taurine sits alongside all of them.

Talk to your vet

If your cat is on heart or kidney medication, mention the addition at her next appointment.
