This was a last-resort order, and the couch is finally safe. The closet was his hiding spot when people came, not anymore. Money extremely well spent.

“Cat fights, accidents outside the litter box, those are the moments that worry us most. Nothing beats a day with no hissing, no scratches, no mess in the wrong place. Since Boelou, we've had more and more days like that.”

"Our cat hid for days after we moved. I heard about Boelou through a friend. It works! Within 2 days, Flow was curled up on our lap again like nothing happened."

"Snoesje used to hiss and scratch at anyone who came in: territorial, I think. Since the diffuser, she even lets strangers pet her and is much more at ease overall."

What does Boelou help with?
From mother nature to NeuroScent™
From an instinct every animal already has to a technology that puts it to smart use. Here's the story in 4 steps:
A safety signal
After giving birth, a mother cat releases a signal that reassures her kittens: you are safe. That signal keeps working for the rest of their lives, even as adult cats
Continuous signal
The diffuser releases a safe, recreated version of this signal into the air all day long, completely unnoticed.
The organ of Jacobson
Your cat doesn't perceive this signal as a normal smell. Instead, it's detected by the organ of Jacobson, a small separate organ at the back of the nose, independent of the regular sense of smell
A calmer brain
From that organ, the signal goes straight to the part of the brain that regulates emotions. As a result, your cat will show calmer behavior within a short time. We call this entire process NeuroScent™
How to use the diffuser
Set up in under a minute, the diffuser takes care of the rest.
1
Choose an outlet
In the room where your cat spends the most time
2
Click in the refill
Twist until it's securely in place
3
Turn on the diffuser
Let it run 3 to 8 hours a day for the best results
Note!
Keep the head facing up, never on its side or upside down, to prevent leaking.

So happy with this, finally a relaxed kitty.
My confidence was well hidden because there wasn't much, and my cats have become much calmer. Give it some time and you'll notice the change. Kicking myself for not trying sooner.
My first reaction was 'waste of money', but the whole house feels calmer. He was off since the relocation, this was the fix. Looks great in the house too. Solid product, no complaints.
Honestly surprised by how well this works. Our two cats who always used to hiss each other out of the room are now lying side by side in the sun. Definitely buying again.
A coworker told me about it and good thing I paid attention — my cat stopped running away from everything. The new baby threw him off completely, this restored the peace. Patience was required, and rewarded. Wish I'd ordered this months ago.
My skepticism was at full blast when I ordered, and Minoes has the courage to come out again. He'd vanish into the closet at every guest, stays in the room now. This is staying permanently.
Instagram brought this to my attention and I ordered, and my cat is visibly more relaxed. A welcome addition to our home staying.
I thought this was going to be a pointless spend, but the household atmosphere has completely shifted. Leaving doesn't devastate him like it used to. Dead simple — just plug it in. Absolutely convinced now.
After a long search I gave this a shot, and Kiara climbs into our laps again without prompting. Consider us fans.
I placed my order with serious doubts, and the fidgety behavior has faded. No complicated anything, it just runs and delivers. Warmly suggest this.
After looking around for months I finally tried this, and litter tray use has returned to normal. Travel crate used to be a nightmare, way easier now. It's a slow build, but the results come. Precisely what we needed.
After trying everything, this was the first thing that actually helped. She's less tense and the hissing at our other cat is nearly gone. A must for anyone who's at their wit's end.
Bought this because a friend raved about it, and Felix has become less anxious and hyper-vigilant. NYE used to be an absolute nightmare, so different now. I'm a complete convert.
We were completely out of options, and my cat hangs out with us again. Getting in the carrier used to be stressful, not anymore. Very satisfied.
Wasn't planned at all but so glad I went for it — our home is so much more peaceful now. The new pup caused upheaval, this settled everything. Spot on for our situation.
We ordered this as soon as the new cat arrived, and Beau has started purring happily once more. Outside noises were always a trigger, he handles them fine now. Stays in the socket 24/7.
Price was a concern, but I took the leap anyway, and furniture destruction has stopped. Totally worth the price. One small con, but the pros overwhelm it.
Our vet thought this might help, so we tried, and Pluis has stopped seeking cover under every piece of furniture. The move really rattled him, this made a huge difference. No hassle at all, just plug and go. Essential for any nervous cat.
I ordered with very low expectations, but Tijger has stopped the overnight meowing marathons. Getting a second cat meant daily battles, they're at peace now. Skip the debate, just order it.
I kept my hopes low on purpose, but our furry one is significantly calmer now. The carrier was always a battle, so much smoother now. Got one for the other room too.
Total impulse purchase, zero regrets . no more sofa scratching sessions. Visitors meant instant closet retreat, he greets them now. Over the moon with it.
This was a completely unplanned buy, and Grijsje hops on our lap by choice again. We placed it in her favorite room. Really pleased with this one.
I was unsure about the price but decided to try, and the mutual hissing has all but ceased. He'd go crazy at every loud bang, now he barely reacts. Light fragrance, nothing overpowering at all. Good product with a minor quibble.
Moving had thrown everything into chaos, so I tried this, and Loki has dropped the fearful watchfulness. Leaving him alone always ended badly, so much calmer now. Trust me, just buy it.
I really didn't anticipate much, but Felix has improved enormously. Really happy with it.
I was desperate enough to try anything, and the sofa has been spared from destruction. Visitors no longer cause a scene. Just plug it in, no setup needed. Every cent was worth it.
So many success stories pushed me to order, and Tijger is way more settled now. Baby arrival was a shock for him, this settled him down. The magic takes a few days to start. Satisfied, with a small caveat.
I braced myself for nothing to happen, but Felix is noticeably more at ease. He doesn't get distressed when we go anymore. We're true believers now.
We got this specifically for the two-cat transition, and Saar faces things with a calm I didn't think possible. Good purchase all in all.
I purchased this when all else had failed, and our kitty is undeniably more relaxed. Putting him in the carrier was a fight, goes in willingly now. Really pleased with the results.
We were at breaking point honestly, and Bowie is in a much better place now. He'd tremble under the bed during bangs, stays right where he is now. Life-changing little thing.
Review after review of praise — I had to experience it myself, and Nino the nonstop night meowing has ceased. The multi-cat tension was real, they actually cuddle now. Should've trusted the reviews earlier.
The good experiences piled up until I had to see for myself, and Poekie is has fixed the litter box situation. Bed-diving at fireworks is over, he barely blinks. Each refill goes the distance. Good value for money.
This was the fastest purchase decision I've ever made, and the jumpy behavior has vanished for good. Pretty good value overall. For stressed-out cats, this is the answer.
We were ready to accept this was just how it was, and Vlek has stopped the nighttime wake-ups entirely. Really glad I tried it.
My search finally ended when I came across this, and Loesje doesn't spiral at triggers anymore. Fair price, great outcome.
Honestly, I thought it was just another fad. It's not. She climbs up for lap time on her own instead of hiding in the closet for hours. Very pleased.
My prolonged search finally concluded with this purchase, and Sushi has become genuinely laid-back. Nose-friendly — barely detectable. It delivers, just go for it.
We'd been struggling with this for longer than I care to admit, and Diva seeks company rather than retreating under the bed in the closet. Visits from friends are no longer a headache. If you're reading this, you already know you should buy it.
Frequently asked questions
How exactly does the diffuser work?+
Dogs and cats communicate not only through sound, but also through scent signals. Right after birth, a mother cat releases a scent that tells her kittens: you're safe. That signal keeps working for the rest of their lives. This scent has been recreated by experts. Not medication or a supplement, but an artificial copy of something that already exists in nature. The diffuser releases this signal into the air, unnoticeably, throughout the day.
What makes Boelou different?+
Thanks to the expertise behind Boelou, we know exactly how your dog or cat picks up this signal best: at what dosage, with what release, and via which pathway to the brain. Not through the regular sense of smell, but through Jacobson's organ. A separate organ at the back of the nose with a direct connection to the calming part of the brain. We call this process NeuroScent™. Thanks to this expertise, we stand 100% behind the effectiveness of our product.
Is it safe for my pet?+
Yes. The liquid contains no medication and no chemical sedatives. It's a recreated version (analogue) of a scent (pheromone) that dogs and cats naturally produce themselves. Odorless to humans, safe around children and other pets. We recommend running the diffuser 3 to 8 hours a day for the best results; if your pet shows visible separation anxiety, the diffuser may also stay on all day.
Does it work for both dogs and cats?+
Yes, for both! But not with the same diffuser. Dogs and cats respond differently to the signal, so there's a NeuroScent™ Diffuser specifically for dogs and a separate one for cats, each with its own dosage and release.
How soon will I notice a difference?+
Most pet parents notice a visibly calmer pet within one to two weeks. But keep in mind: every animal is different, so feel free to give it some time.
How long does a refill last?+
At the recommended use of 3 hours a day, a refill lasts approximately 30 days, in a room up to 60m². If you run the diffuser more hours a day (up to the full day for visible separation anxiety), the refill will run out sooner based on usage.
What if it doesn't work for my pet?+
Get in touch with our customer service and we'll find the best solution together. Try Boelou for 30 days — there's always a solution that fits.
What type of plug does the diffuser have?+
The diffuser has a fixed European plug (type C, also known as the Europlug).
