Whole-Cat · Taurine Drain Support

Built for cats whose bodies need more than taurine alone.

Your cat isn't "just getting older." Every cooked meal drains taurine she can't replace fast enough — and plain taurine only fixes one part of the problem. Whole-Cat puts back taurine plus the L-Carnitine and CoQ10 her heart actually runs on.

Taurine + L-Carnitine + CoQ10 in one daily scoop

Never-cooked taurine — not heat-degraded like food

Tasteless & odourless — no mealtime battles

One precise scoop a day — no guesswork

The Taurine Drain

The missing nutrient behind so many "healthy" cat diets

Cats can't make taurine on their own — it's an essential amino acid their heart, eyes and digestion depend on every single day. And they're uniquely poor at holding on to it.
 

Here's the quiet problem: modern pet-food processing can destroy a large share of the taurine that should be there. Even expensive "premium" and "complete" diets can fall short — leaving your cat's most vital systems working with less than they need.
 

The drain is silent, and it never stops. One scoop a day is how you close the gap.

Based on Hickman, Morris & Rogers (1990), Journal of Nutrition — daily taurine balance −609 µmol on a heat-processed diet vs −212 µmol minimally processed.

More Than Taurine

Why taurine alone isn't enough

Taurine is essential — but it only does one job for the heart: it helps fire 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 Spark

Taurine

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

The Delivery Truck

L-Carnitine

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

The Spark Plug

CoQ10

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

A plain taurine powder gives your cat one of three. Whole-Cat gives all three in one daily scoop — the whole cat, not one part.

A Plain Taurine Pot

  • 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

*Supports normal structure and function. Not intended to diagnose, treat, cure or prevent any disease.

What Whole-Cat Protects

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 one scoop helps protect.

Heart Support

Taurine plus the co-factors heart muscle uses for energy — for steady, everyday 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.

*Supports normal structure and function. Not intended to diagnose, treat, cure or prevent any disease.

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.

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

Everything you might be wondering

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.

What's your guarantee?

60 days, money-back. If you're not satisfied for any reason, contact us for a full refund. Subscriptions can be cancelled anytime.
