VET REVEALS: Why your cat ends up under anesthesia for a dental cleaning every year (and how to stop the cycle at home)
The cleaning removes the tartar. It can't stop the plaque that starts again with her very next meal.
By William Brown, DVM · March 14, 2025
You saw it in the video. The food bowl taken away. The carrier. The cold room where she wakes up alone.
If you've ever driven home with a groggy cat in the back seat, you know that day.
This page is about all the days in between.
One "routine" dental cleaning, seen from inside the carrier
The night before: her food is taken away. She waits by her bowl and doesn't understand why.
The morning: the carrier comes out. She knows that carrier.
At the clinic: a shaved patch on her leg, an IV, general anesthesia, a tube down her windpipe.
Waking up: a cold room, wobbly legs, a mouth that feels strange. And you're not there.
The drive home: her teeth look clean. You hug her. Everyone thinks: now it's over.
But with her very next meal, it starts all over again. And a year later, the carrier comes back.
Stop the cycle nowWhy it keeps coming back
The cleaning resets the clock. It doesn't stop it.
Every time she eats, her saliva coats her teeth with a paper-thin layer of protein. Bacteria stick to it and form plaque, and minerals in her saliva harden it into tartar. That's the hard crust your vet scrapes off under anesthesia.
But the film starts again with her very next meal. Nobody at the clinic can change that. If nothing happens at home, the tartar grows back, her gums get red and sore, and the carrier comes out again.
And she won't tell you when it starts to hurt. In the wild, a cat that showed pain became prey. So she keeps eating, comes to you on the couch, maybe even purrs. Often all you notice is her breath.
Her life, year by year
A cleaning every year
15× under anesthesia
With daily care at home
Further apart, more quiet years at home
Age in years. Illustration, every cat is different.
If she gets a cleaning every year, that's 10 to 15 times under anesthesia over her life. And every time, she's a little older.
Why nothing you've tried at home has worked for long
You've probably tried something already. And it didn't last. That's not your fault. It's about where those fixes work.
✕Dental treats
Gone after two bites. She decides which side she chews on, and for how long. And most cats barely chew at all: "they seem to almost swallow them whole, I don't hear them crunching." Almost nothing reaches the gums in the back.
✕The toothbrush
Works, if she lets you, every single day, all the way to the back teeth. Most cats don't. When you hold her head, her instinct says she's being attacked. Soon she hides as soon as she sees the brush. One owner asked a vet if she brushes her own cat's teeth: "Oh god, no, I enjoy having fingers."
✕Booking the next cleaning
Takes the pressure off for a while. But it means general anesthesia again, owners report paying $800 to $1,600 each time, and the film comes back with her very next meal.
All of them either need her to cooperate, or come after the damage is done.
None of them work where the film starts: in her saliva, at every meal.
For the days between checkups
Novendo works on the soft film every day, before it can harden. Its 3-step formula mixes with her saliva at every meal, right where the film starts:
- Cuts into the plaque, so it can't keep building up
- Goes after the bacteria that make her gums red and inflamed
- Soaks up what they leave behind, including the smell
And how do you use it? One scoop on her regular food, done. Not even 10 seconds. No towel, no toothbrush, no fight. It tastes like chicken, so she sniffs it once and keeps eating.
See the offerHow it works
Three natural active ingredients, one for each step
Malt sprout extract
An enzyme that works like a tiny pair of scissors. It cuts into the framework of the plaque and slices it apart.
Beet extract
The nitrate it contains hunts down the bacteria along her gumline.
Natural zeolite
Works like a sponge that soaks up the smelly compounds and locks them inside its tiny pores. So bad breath isn't covered up. It's gone.
Natural chicken flavor
So she eats it on her own, without even noticing it's there. No hiding it in treats, no holding her down. 99.6 % of cats eat it without any fuss, picky eaters included.
Made for every day
Five ingredients. No seaweed. Nothing hidden.
Most dental powders are made from seaweed, which means a lot of iodine in her food, every single day. Novendo went a different way: a seaweed-free formula with no added iodine, made to be a safe daily routine. It never goes in her water. Five ingredients, and every amount is printed on the label. Every batch is lab-tested before it is filled, and it's made in an FDA-registered facility.

Thank you so much for this valuable product
Before we started, my cat had very bad breath. Her teeth were already yellowed and she had inflamed gums everywhere. […] It must have hurt a lot, because she kept dropping dry food next to her plate while eating. […] By the second week her breath was already much better. The teeth and the gums got lighter. From the third week on her gums were no longer inflamed.
[…] I have two cats, and the tom has a bit of plaque. He is eight years old […] Week by week there is less plaque and I expect it to disappear completely. […]
This product is amazing!
Before, we were fighting a lot of plaque on the teeth, and since November that has stopped. Happy to buy again🙌🏻
The bad breath is gone, my tomcat just will not show me his teeth 😂 so I do not know yet how they are doing.
Great product. The cat takes it without any trouble. It showed an effect after a short time. The customer service is excellent too. A clear recommendation.

Plaque comes back after every meal, so it can't be fixed overnight. A jar lasts about 30 days. Most cat parents notice fresher breath within 1–2 weeks, and less plaque takes 3–6 weeks of daily use. That's why the 3-tub pack is the best value: about 90 days for $0.63 a day.
Malt sprout extract complex 979 mg, silicon dioxide 10 mg, natural chicken flavor 10 mg, zeolite powder 0.6 mg, beetroot extract 0.6 mg. No algae, no added iodine.

Your questions, answered
Does this mean she'll never need another cleaning?
No, and nobody honest can promise that. Tartar that's already there, a damaged tooth or tooth resorption are jobs for your vet, and no powder replaces that. What you can change is the soft film that builds up every day between checkups. Less of it means less to scrape off next time.
What if she has tooth resorption?
Then she needs a dental X-ray and the right treatment. Novendo isn't for that. But one affected tooth doesn't mean all the others are damaged. Her healthy teeth still collect fresh plaque every day, and those are the teeth Novendo is for.
Does it remove the tartar that's already there?
No, and we'd rather tell you now. Tartar that has already hardened won't dissolve from any powder. That's a job for your vet. Novendo works on the soft plaque that builds up every day.
Will she even eat it?
That's where most dental powders fail. On Chewy, "my cat won't eat it" is the most common one-star complaint about them. Novendo tastes like chicken and goes on wet or dry food, so she eats her meal like always: 99.6 % of cats eat it without any fuss. You'll know on day one. And if yours won't, you get your money back.
How fast will I see a difference?
Most cat parents notice fresher breath within 1–2 weeks. Less plaque takes 3–6 weeks of daily use. Take a photo of her teeth on day one and look again after 30 days. You have 60 days to decide.
Is it safe for an older cat? Her kidneys? Her thyroid?
Novendo has no algae and no added iodine. If she's on a kidney diet or medication, show your vet the label: all five ingredients are listed with their amount in mg.
Doesn't her kibble or dental treats already clean her teeth?
Most cats barely chew their kibble. They swallow it almost whole, so it never scrapes along the gumline, where the plaque starts. With treats, she decides which side she chews on and for how long.
How do I use it?
Once a day over her usual food. Stir it into wet food so the powder spreads, or sprinkle it over dry food. Don't dissolve it in water, it clumps.
How much does she get, and how long does a jar last?
Under 15 lbs: half a scoop a day. 15 lbs and over: one full scoop. A jar lasts about 30 days. The scoop is in the jar.
Will it upset her stomach?
If she has a sensitive stomach, start with half a portion, stirred into wet food, and move up to the full amount after three or four days.
What exactly is in it?
Per full scoop (1 g): malt sprout extract complex 979 mg, silicon dioxide 10 mg, natural chicken flavor 10 mg, zeolite powder 0.6 mg, beetroot extract 0.6 mg. Nothing else. Made in an FDA-registered facility, and every batch is lab-tested.
I have more than one cat.
Each cat gets her own portion on her own food. With more than one cat, a jar runs out faster, so the 2- or 3-tub pack makes the most sense.
Isn't that expensive for a powder?
It's as little as $0.63 a day with the 3-tub pack. One cleaning costs $800 to $1,600, and the plaque starts again with her next meal.
Is there a subscription?
Only if you want one. You can buy once, or subscribe and save 20 %. No minimum term: cancel anytime in your account or by emailing support@novendo.shop.
How fast does it ship, and what does shipping cost?
Orders ship within 24 hours. Shipping is free on 2 or more jars.
How does the money-back guarantee work?
You have 60 days from delivery. If your cat won't eat it or you're not convinced, email support@novendo.shop with your order number. That one email is enough, and you get your money back. It covers your first subscription delivery too.
Can I talk to someone before I order?
Yes. Email support@novendo.shop and a real person answers, not a ticket bot.
