Full description
For spraying in the same corner, scratching the same arm of the sofa, hiding when guests arrive.
One socket, thirty nights, working on its own. Nothing to feed her, nothing to swallow.
What Stillroom does
The vial holds a synthetic copy of the scent a cat leaves when she rubs her cheek along a door frame. That mark means: this is mine, and nothing bad happens here. The diffuser warms the vial and keeps that message in the room, day and night.
Where it earns its place
A move, a new baby, a second cat, a foster, a dog that visits. A cat who has started marking after years of never marking. Two cats who were fine until something shifted. A cat who vanishes under the bed when the doorbell goes.
Using it
Twist the vial into the base, hand tight. Plug it in upright in the room she spends her day in. Never behind furniture. Leave it running for a full month before you judge it.
Where it will not help, honestly
If she squats and empties her bladder on the floor, check the litter box first, then your vet. Marking is not the same as a litter box problem.
Why it works
Three things nobody else tells you.
The blame
It is a signal, not a character flaw.
Nothing here is about discipline. The behaviour is information, and information can be answered.
The mechanism
A copy of the calm signal.
Synthetic pheromone analogues have been used in veterinary practice for over twenty years. They are a signal, not a sedative.
The honest clock
Judge it at thirty nights.
Most people quit on day four because they expected day one. The change usually shows in the second half of the month.
Three steps
Plug it in. Leave it. Decide at thirty.

You have tried the rest
What the alternatives actually cost.
A behaviour consult at the vet
An appointment, a carrier, a frightened cat, a bill
Something in the food
A daily fight, and a cat who learns to distrust the bowl
Cleaning it again
The mark is gone. The reason is not. Thursday it is back
Living with it
A closed door, a rug you replace, a room you stop using
One socket. Thirty nights. Nothing swallowed.
The evidence
What the research actually found.
- Effect found
In 1,060 cat and owner pairs, unwanted scratching fell over 28 days for 83.5 percent on the pheromone against 68.5 percent on placebo.
Funded by the manufacturer Ceva, and three of the authors worked there. Strong design, interested sponsor.
Pereira et al., PLOS ONE, 2023 — randomised, triple-blind, placebo-controlled
- Mixed
A review for veterinary practice found the feline facial analogue can lower acute stress signs at the clinic and is unlikely to do harm.
The same review says plainly it should not be the only thing you do.
- Effect found
Cats travelling by car showed lower stress indicators with the feline facial analogue than without it.
A pilot study, so small numbers.
Shu and Gu, Journal of Feline Medicine and Surgery, 2022 — randomised controlled pilot
- No effect
A systematic review of the field concluded there was insufficient evidence for most uses in both cats and dogs.
The authors found published success rates for urine marking overstated, because owners who dropped out were left out of the results.
Frank, Beauchamp and Palestrini, JAVMA, 2010 — systematic review
The evidence is real, and it is mixed. That is why you get thirty days to decide, not a promise.

Before you buy
Six questions we get every week.
How long until I see a change?
Most of it happens in the second half of the first month. Watch where she chooses to sit before you count incidents. That is why the guarantee runs 30 nights.
Is it safe around children and other pets?
Nothing is swallowed and nothing is sedated. The version for cats carries no message a dog or a person can read. Keep the vial out of reach.
When does it arrive?
Ships from our US warehouse and arrives in 2–5 business days. We ship within one business day.
What if it does not help?
Write to hello@pheroniapets.com within 30 nights and we refund the whole order. You keep the device. One claim per household.
Do I need to clean the spot first?
Yes, with an enzyme cleaner, not an ammonia-based one. We do not sell the cleaner.
Can I use it with a second cat in the house?
Yes, and with two cats it usually matters more. Give each of them a room with its own device.
All questions
Goes with it
It stays in the room. For the carrier, the car and the clinic, that is the collar.
