Your cat isn’t “just getting older.”

Every meal drains taurine they can’t replace fast enough.

Plain taurine only solves one part of the problem.

Whole-Cat puts back taurine — plus L-Carnitine and CoQ10 — to support the heart, eyes, digestion and energy in one daily scoop.

✓
Whole-Cat Complex — taurine, L-carnitine & CoQ10 in one daily scoop
✓
Never-cooked taurine — not heat-degraded like taurine in processed food
✓
Replaces what meals drain — helps put back taurine cats lose every day
✓
Tasteless & odourless — mixes into food without turning mealtime into a fight
✓
Precise daily dose — one included scoop, no measuring, no guesswork

Don’t wait for “slowing down” to show up — by then the Drain has been building for months. Start the daily habit today.

More Than Taurine

Why Taurine Alone Isn’t Enough

Taurine is essential — but it only does one job for the heart: it helps the signal that makes the muscle contract. A heart that contracts still needs fuel to keep going, every second, for life. That’s the part a plain taurine pot leaves out.

The three things a cat’s heart actually runs on:

⚡

Taurine

The spark

Helps trigger each heartbeat, and supports vision and digestion too — and it’s what your cat loses every single day.*

🚚

L-Carnitine

The delivery truck

Carries fat into the cells to be burned, so the heart and muscles have fuel to actually work with.*

🔌

CoQ10

The spark plug

Helps each cell turn that fuel into usable energy — a nutrient the body naturally makes less of as cats get older.*

Taurine alone tops up the signal but leaves the engine half-fuelled. A plain taurine powder gives your cat one of the three.

Catlyst Whole-Cat gives all three in one daily scoop — the whole cat, not one part.

  • ✗ Taurine only — one of three
  • ✗ No L-carnitine or CoQ10
  • ✗ The signal, but no fuel
Catlyst Whole-Cat
  • ✓ Taurine + L-carnitine + CoQ10
  • ✓ Never-cooked, full-dose taurine
  • ✓ One tasteless scoop a day

Why Whole-Cat Works

What the Taurine Drain Quietly Takes

Taurine touches the heart, eyes, digestion and energy. Lose it every day — and every one of these is left short. Here’s what Whole-Cat protects.

❤️

Heart Support

Taurine and the co-factors heart muscle uses for energy — for steady, everyday heart support.*

👁️

Clear Vision

Taurine helps keep the retina nourished — part of why cats need it daily.*

🔥

Energy & Vitality

L-carnitine and CoQ10 help cells turn food into usable energy.*

🥣

Healthy Digestion

Taurine plays a role in bile and fat digestion — supporting a settled tummy.*

🍳

Never-Cooked Taurine

Unlike food, our taurine isn’t heat-degraded — so the full dose reaches the bowl.*

⏱️

Effortless Daily Habit

An odourless scoop that stirs into any food. Even fussy cats don’t notice.*

The Science Behind Whole-Cat

Your Cat’s Own Body Is Working Against Them

Cats can’t recycle taurine — and cooked food more than doubles what they lose each day. The Taurine Drain is silent, and it never stops. One scoop a day is how you stop it.

"Finally, more than plain taurine."

My 12-year-old cat has been slowing down, and I wanted something simple that wasn’t just plain taurine. Whole-Cat mixes into wet food easily, and she doesn’t seem to notice it at all. I like that it has taurine, L-carnitine, and CoQ10 in one scoop.

"No food battles, no weird smell."

I’ve bought taurine powder before, but this feels more complete. My cat eats it with breakfast every day, no drama. The biggest win for me is that it’s tasteless and easy to keep consistent.

"A simple daily habit I feel good about."

My senior cat has been less playful lately, so I wanted something gentle to add to his routine. I can’t say it’s magic, but he’s eating well, moving around more, and I feel better knowing he’s getting taurine plus the extra co-factors.

Rachel B. - Tampa, FL · Verified Buyer

"Bought it before problems show up."

I bought this for peace of mind. My cat is healthy but getting older, and I wanted daily nutritional support before problems show up. I like the formula and the no-nonsense branding.

questions

FAQs

How is this different from regular taurine powder?

Two ways. First, it’s not taurine alone — it adds L-carnitine and CoQ10, the co-factors heart muscle uses for energy, for whole-heart support. Second, the taurine is in a protected form designed so more survives digestion and is absorbed.

My cat’s food says “complete and balanced.” Why add this?

“Complete” reflects a minimum measured at the factory. Heat processing, storage and your cat’s own digestion reduce taurine over time — and cats are uniquely poor at conserving it. A daily scoop gives a consistent safety margin.

Is it safe? Can I give too much?

Taurine is water-soluble and any excess is naturally excreted, which is why it’s well tolerated for daily use. Follow the dosing scoop for your cat’s weight. As always, check with your vet if your cat has a health condition or is on medication.

Will my fussy cat eat it?

It’s an odourless, tasteless powder that mixes into wet or dry food. Most cats don’t notice it. For very fussy eaters, start with a smaller amount and build up.

How long until I notice anything?

This is daily nutritional support, not a quick fix — much of the benefit is what you don’t see. Some owners report brighter energy and coat over a few weeks; consistency is what matters most.
