Simba, Nala & 40,000+ cats already calmer with Boelou
I Fixed My Cat's Spraying By Plugging Something Into The Wall
Three vet visits and a new litter box later, it turned out he wasn't being bad. He was stressed.
End The Stress TodayWhat Boelou Owners Are Saying

Lying side by side in the sun
I'm honestly surprised by how well this works. Our two cats, who are always chasing each other out of the house, are now lying side by side in the sun. I'll definitely buy it again.

Plug and play, no hassle
Just great. Every time we visited, our cat would hide, but now she just lies there comfortably. Plug and play.. no hassle with batteries or anything like that. I'd buy it again in a heartbeat.

It just works, period
No complicated fuss, just plug it in and it does its job. The vacuum cleaner always used to cause a panic, but the other day she just lay there without moving. I'm a happy person here.
Your Cat Isn't Being Bad. He's Scared.
He's not marking your bed to spite you. He's marking it because it smells like you, and right now you're the safest thing in the house.
That's what stress looks like in a cat. Fights over a food bowl that was never a problem before. Claws in the armchair. A wet patch by the front door.
It hits hardest in two situations: a second cat arriving, or a rescue settling into a home he doesn't trust yet. He's working out whether this place is his, and he answered that by smell.
Sort it now. Once the spraying becomes a habit, it's much harder to undo.
Ease My CatYou've Already Tried Everything. He Still Sprays.
More boxes help in a multi-cat home. But they don't stop marking. Marking isn't about needing a toilet.
Most owners buy a second box. A week later, the same wet patch is by the door.
Most diffusers are built for a small room. In an open kitchen or hallway, the scent thins out before it reaches your cat.
They get rid of the smell. They don't get rid of the reason.
Your house can be spotless and he'll still spray, because the stress that made him do it is still there.
Most owners think the litter is the problem. It rarely is. He knows where the box is. He's choosing not to use it.
You can try pine, walnut, or the attract stuff. He'll still go by the door.
Keeping them apart stops the fighting. It doesn't fix what's between them.
They're still on edge. Open the wrong door and they pick up right where they left off.
Scent swapping and short meetings work if the cats are just nervous about each other.
But if they've already fought, they remember. Weeks of slow introductions won't undo that history.
Don't Give Up On Your Cat
You don't need a better-behaved cat. You need a calmer one.
The behavior is the stress leaking out. Fix the stress, the behavior goes with it.

How It Works
We use pheromones because a mother releases them just after birth to tell her young kittens they're safe.
Having Boelou diffusers around your home releases those pheromones automatically, keeping your pet calm all day, unnoticed.
- Less Stress & Tension

- Reduction in Meowing & Scratching

- No More Spraying Outside Litter Box

- Reduction in Hiding & Anxiety


"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."
