"Most commercial cat foods add taurine. But the amount that actually survives processing and reaches your cat's heart is a very different number from what's printed on the bag."
Built on nearly 40 years of feline taurine research
In 1987, veterinary researchers linked taurine deficiency to serious heart disease in cats. Food makers responded by adding taurine to the bag. But here's what nobody mentioned: heat processing can more than double the taurine a cat loses every day — and cats can't make enough of their own to cover the gap.
Whole-Cat puts back never-cooked taurine. Then it adds the two co-factors a plain taurine pot leaves out, so the heart doesn't just get the signal — it gets the fuel to act on it.
Hickman, Morris & Rogers (1990), Journal of Nutrition — daily taurine balance −609 µmol on a heat-processed diet vs −212 µmol minimally processed.
Is your cat fading — and you've been told she's just getting old?
Sleeping more. Skipping the jump to the counter. A coat she's stopped grooming. These are also the early signs of a heart and muscles that aren't getting the fuel they need. Whole-Cat is the only daily scoop that puts back the taurine every meal drains and gives her cells the two co-factors that turn food into energy — so she can get back to being herself.
Goodbye to the slow fade
Never-cooked taurine puts back what every meal drains, so the heart gets its signal every single day — not just what survived the factory.
Energy to jump, play and groom again
L-carnitine carries fuel into the cells. CoQ10 burns it. That's the part a plain taurine pot leaves out — and the part that brings the crinkle-ball back.
One tasteless scoop. Any food.
No pills. No food fights. It stirs into wet or dry food and even the pickiest cat has no idea it's there.
A healthy heart needs more than taurine
Whole-Cat has three active ingredients, and each one does a different job. Most cat supplements stop at taurine. It's essential — it's the spark that tells the heart to contract. But a spark with no fuel and no engine doesn't move anything.
Taurine
Helps trigger each heartbeat and regulates calcium in the heart muscle. It also builds the bile cats need to digest fat — which is exactly why they lose it every single day.
L-Carnitine
Fat can't get into a cell's power plant on its own. L-carnitine is the truck that carries it through the door so the heart and muscles have fuel to actually work with.
CoQ10
Turns that delivered fuel into usable energy — and sweeps up the exhaust while it does. A nutrient cats naturally make less of as they get older.

Thousands of cats back on the counter
Whole-Cat is the only daily scoop that puts back the taurine every meal drains and fuels the cells that turn it into energy — so cats get back to the life they love. Safely, and without a single food fight.
When will you see results?
This is daily nutritional support, not a quick fix — much of the benefit is what you don't see. But the gap closes from day one, and the longer you stay consistent, the more it shows.
The routine sets in
Most cats take the tasteless scoop straight away, even fussy ones. You've closed the daily taurine gap — the drain has stopped.
Small signs
Some owners notice brighter energy and a cat that starts grooming herself again.
More of her old self
More interest in play, more willingness to jump. Consistent support for heart, vision and digestion.
An automatic habit
Steady nutritional insurance for the systems a cat's body can't safeguard on its own. Peace of mind that doesn't depend on the label.
Results and timelines vary by cat. Check in regularly with your vet to track progress.
One scoop. Once a day. That's it.
No weight charts to decode. Stir one level scoop into your cat's food once a day — wet or dry, morning or evening. It's tasteless and odourless, so most cats never know it's there, and the results build the longer you stay consistent.
- 1Scoop. One level 2 g scoop from the tub — the scoop's included.
- 2Stir. Mix into wet food, or sprinkle over kibble.
- 3Serve. Same time every day. That's the whole habit.

Why not just give my cat plain taurine?
Good instinct — taurine is the right place to start. But it only does one job: it's the spark that tells the heart to contract. A working heart also needs fuel to burn (that's L-carnitine) and an engine to burn it (that's CoQ10). Plain taurine gives your cat one piece of a three-piece puzzle.
There's a second difference: our taurine is never-cooked and protected, so more of it survives digestion instead of being lost before it's absorbed.
How long does it take to work?
You close the daily taurine gap from the first scoop. What you can see takes longer — some owners report brighter energy and coat over a few weeks, others notice their cat playing or grooming again around a month in. Consistency matters most, which is why the 4-tub deal is our most popular.
What if my cat won't eat it?
It's a tasteless, odourless powder that stirs into wet or dry food — most cats don't notice it at all. For very fussy eaters, start with half a scoop and build up over a few days. And if it still doesn't work out, you're covered by the 60-day money-back guarantee — even on opened tubs.
Is it safe? Any cats who shouldn't take it?
Taurine is water-soluble and any excess is naturally excreted, which is why it's well tolerated for daily use in adult cats. Whole-Cat isn't formulated for kittens. If your cat is pregnant, has a diagnosed health condition or is on medication, check with your vet before adding any supplement.
What's your guarantee?
60 days, money-back, for any reason. If you're not more confident about your cat's heart health — or you just don't love it — contact us and we'll refund your full order. Even if the tubs are open.
A healthier cat — or your money back
Here's the deal. Try Whole-Cat for 60 days. If you don't see the life come back into your cat's eyes — or for any reason at all — let us know and we'll refund your entire order. Even on opened tubs.
We can offer that because of the research behind the formula, and because we've watched what happens when thousands of cats finally get all three pieces of the puzzle instead of one. Which is probably why so few people ask.

"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.
