MV Story: Adored, but teeth unbrushed

The setting is a slice of daily life.

A beloved cat eats its food with relish. Plenty of treats, too. The owner watches this adorable sight with a fond smile.

—But, their teeth are not being brushed.

The moment the owner leans in close, a peculiar smell wafts from the cat's mouth. With a troubled expression, the owner picks up "Eating Tooth-brushing Revolution." Sprinkling it gently on the food, the cat eats it all up just as deliciously as before.

A few days later—the owner can naturally lean close to the cat in their arms.

Finally, a single line quietly appears on the screen.

"When was the last time you brushed their teeth?"

—Dog Diner

Background of the Release: A quiet question to cat lovers

The sixth installment is the first to focus on cats.

"My cat is so cute," "I'm careful with its diet because of allergies," "I give it supplements because it's frail"—the number of owners who love their cats and introduce them as proud family members on social media is increasing year by year. This in itself is wonderful.

However, this time, we wanted to pose a single question.

Even if they eat their meals, even if they eat treats, their teeth are not brushed—is that really okay?

While worrying that "my pet is frail" or "has allergies," oral care is left behind. Social media is filled with cute pictures of their cats, but inside their mouths, periodontal disease is quietly progressing—such owners are not few and far between.

Periodontal disease is the root of all illnesses. Heart, kidneys, liver—periodontal bacteria travel through the bloodstream and erode the pet's health itself. In some cases, the state of the oral cavity is even related to the cause of "allergies" or "frailty." Precisely because you love them, we want you to make oral care not a "special thing" but a "matter of course"—that is the core of this work.

Furthermore, there is the reality that brushing a cat's teeth is even more difficult than a dog's. The moment a toothbrush enters their mouth, they scratch, bite, and run away—a wall many owners face. That is why we believe the option of "just sprinkling on food" has even greater significance for cats than for dogs.

The final question, "When was the last time you brushed their teeth?" is not meant to blame anyone. We want you to just stop and ask yourself—we believe that small trigger can change your beloved cat's future.

Risks of Periodontal Disease in Pets

About 80% of dogs over 3 years old have periodontal disease (American Veterinary Dental College)

It is pointed out that cats similarly face a rapidly increasing risk of periodontal disease with age.

Dogs with severe periodontal disease have a death risk about 1.4 to 1.6 times higher (large-scale survey by Banfield Pet Hospital in the US)

It is pointed out that periodontal bacteria can also affect the heart, brain, and kidneys via the bloodstream.

Periodontal disease is the root of all illnesses—we believe that before worrying about allergies or frailty, you should first review oral care.

【Our Commitment: All Ingredients Disclosed】

Our company does not use ambiguous labeling with unclear contents like "XX extract" or "proprietary flavor components." All ingredients used are disclosed on the package and product page.

Dogs and cats cannot rinse their mouths or spit out food. They take everything they are given into their bodies. That is why we believe owners should be in a position to clearly understand what they are giving their pets.

Moreover, a diet high in additives can itself be a cause of bad breath. "Eating Tooth-brushing Revolution" is a completely additive-free product that pursues the dual goals of oral care and overall health.

Comment from the CEO (Masako Ishida)

"I have never once seen a dog or cat finish their meal and head to the sink saying, 'Well, I'm off to brush my teeth.' Humans can protect their own teeth, but pets cannot. That's why we, the owners, have to do it.

This Vol. 6 is the first in the series to focus on cats. And I intended to make it the quietest and most profound one yet.

Looking at social media, I see many owners posting cute pictures of their cats. 'I'm careful with their diet because of allergies,' 'I'm worried because they are frail'—the depth of their love comes through in every word.

But to those owners, I want to ask just one thing.

When was the last time you brushed their teeth?

I'm not blaming you. I myself have moments when I'm busy and think, 'Maybe it's okay for today.' Brushing a cat's teeth is especially difficult—they bite, they scratch, they run away. I understand the feeling of giving up.

But those 'maybe it's okay for today' moments pile up, and before you know it, months, even years, have passed without brushing—what is that state of affairs doing inside your beloved cat's body? It's progressing quietly, behind the happy photos on social media.

And recently, there's something I really want to convey.

I want people to know more about the horror of periodontal disease.

Periodontal disease is the root of all illnesses.

To the owners who say, 'My pet has allergies,' 'My pet is a bit frail,' I want to ask: Are you brushing their teeth?

To the owners who are upset, saying, 'Their heart suddenly got worse,' 'Their kidneys have weakened for some reason,' I also want to ask: Were you brushing their teeth?

Periodontal bacteria spread from the mouth to the entire body. The mouth has countless tiny blood vessels, and the speed at which bacteria circulate through the body is surprisingly fast. This becomes a trigger for heart disease, kidney disease, diabetes, and dementia.

In the human world, the government promotes dental check-ups to reduce medical costs. Because they know that treating periodontal disease early reduces major illnesses.

And periodontal disease is a disease that, once contracted, cannot be cured.

It is said that almost 100% of people with diabetes also have periodontal disease. That's how closely it is linked to overall health.

—However, it is also a disease that can be prevented with daily brushing.

Humans can brush their own teeth. When we are children, our parents brush them for us.

For dogs and cats, it is up to the owner to protect them from periodontal disease for their entire lives.

To those who raise their voices saying, 'Stop animal cruelty,' 'Don't abandon dogs and cats,' I want to ask:

'Are you truly taking care of your beloved dog or cat?' How is neglecting to brush their teeth and leaving periodontal disease unchecked different from slow-motion abuse?

80% of dogs over 3 years old have periodontal disease—I believe this number is a figure of human ego, showing that many owners are not providing care.

You rush to the vet in a panic after they get sick. You regret it when it comes to surgery. But it's too late.

So please, brush their teeth every day. If it's difficult, 'just sprinkling on their food' is enough. That alone can change the future."
