Dana M. with Milo
"Milo sleeps on my chest, so his yawns land right on my face. Around week four I realized I'd stopped turning away. I cried a little, honestly."
ONLY AVAILABLE HERE
We're not on Amazon, on purpose. Untested kelp can carry enough iodine to stress a cat's thyroid. Every tub here is batch-tested to under 100mcg per dose; anything sold elsewhere isn't ours, and isn't tested.
More Moons helps with
Stinky breath
Plaque & tartar
Brushing battles
Picky eaters
In their own words
Cats can't leave reviews.
The people who love them can.
No more turning my head
"I ordered this after googling 'cat bad breath' at 2am and scaring myself half to death. Garfield is 9. It worked three weeks in his breath is honestly fine now, no more turning away when he headbutts me in the morning. Whatever extra time we get together, I'll take it."
70 cents a day vs. $1,400
"My vet quoted $1,400 for a cleaning with 'possible extractions' and I nearly fell over. Started this powder while I saved up. At the recheck the tartar on his back teeth had visibly gone down and the vet asked what I'd changed. Cleaning is postponed."
She still has no idea
"My cat detects and rejects every pill pocket, powder and 'invisible' supplement known to man. She has NO idea this is in her food two months and she hasn't caught on once. And it actually works: her breath doesn't clear the room anymore and the yellow on her back teeth is fading. 5 stars."
That breath isn't just breath.
By the time you can smell it, here's what's usually already happening.

Of us don't brush

Look fine, but aren't
Dental X-rays find disease in 4 out of 10 cats whose teeth looked perfectly normal at checkup.
60%
Of every tooth is hidden
More than half the tooth sits below the gumline where trouble starts, and where a brush can't reach.
They eat. It works. That's the whole trick.
How it works:
Sprinkle
One scoop over their regular dinner, wet or dry, no change of food.
It spreads as they eat
The active dissolves into their saliva and reaches every tooth including the back ones a brush would never touch.
Buildup lets go
Over the weeks, plaque softens and existing tartar starts to loosen its grip.

Results run on their biology, not our marketing.
What to expect:
Weeks 1–2
Working invisibly
The active builds up in their saliva. Nothing to see yet that's normal, not failure.
Weeks 3–4
The breath turns
Usually the first thing owners notice the cuddle test gets easier.
Weeks 5–8+
You can see it
Buildup softens and starts to lift. Their next checkup gets easier too.

Everything owners ask first
What if they won’t eat it?
+
Start with half a scoop mixed into wet food for the first week. The carrier is chosen specifically for palatability most cats never notice. If yours is the exception, the 30-day guarantee covers you, empty tub included.
Is it safe?
+
One natural active, dosed for cats not a shrunk-down dog formula. Iodine per dose is capped well below feline limits, which matters for thyroid health. If your cat has a diagnosed thyroid condition, check with your vet first.
What's actually in it?
+
Cold-harvested North Atlantic kelp plus a food-based carrier for taste. No artificial flavors, no fillers, no grain. Full panel on the tub and on this page.
How long until I notice something?
+
Breath usually turns around weeks 3–4. Visible change on the teeth takes 5–8 weeks of daily use that's the biology of how the active works, and why the guarantee is longer than the timeline.
I have more than one cat.
+
One scoop per cat, per day, on each bowl. With two cats a tub lasts half a moon subscriptions can be doubled so you still never run out.
What if I miss a few days?
+
Nothing breaks. It works by accumulation, so just pick back up consistency beats perfection.
