Full description
For the Stillroom you already own, when day thirty arrives and the room still needs the signal.
The base is only a warmer. Everything that does the work is in the vial.
Why the refill matters more than the device
The households that see a difference are almost always the ones that never let it run dry during the weeks after a move, the first month with a second pet, or the season of fireworks.
Fits
Every Pheronia Stillroom diffuser base, for cats and for dogs. Twist the old vial out, twist the new one in, hand tight. Nothing else changes.
How many you need
One vial is thirty days in one room. Two vials are sixty days, or two rooms for a month.
Good to know
Replace the vial on day thirty even if you can still see liquid. The last millilitres release far less than the first.
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
Pull the old vial. Twist in the new one. Note the date.

Where this will not help.
We would rather lose the sale than take it under a false expectation.
Which shape
Each one loses a line on purpose.
That is how you know the rest is true.

You have tried the rest
What the alternatives actually cost.
A behaviour consult at the vet
An appointment, a carrier, a frightened animal, a bill
Something in the food
A daily fight, and an animal 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
Seven 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 they choose to sit before you count incidents.
Is it safe around children and other pets?
Nothing is swallowed and nothing is sedated. Keep the vial itself out of reach. Use the version that matches the animal.
When does it arrive?
Ships from our US warehouse and arrives in 2–5 business days.
What if it does not help?
Write to hello@pheroniapets.com within 30 nights and we refund the whole order. Unopened vials you can send back. Opened ones you keep. One claim per household.
Do I need to clean the spot first?
Yes, with an enzyme cleaner, not an ammonia-based one.
Does it fit the diffuser I already have?
It fits the Stillroom base that came with your diffuser. It does not fit other brands. Cat vial in the cat device, dog vial in the dog device.
Can I use it with a second animal in the house?
Yes. Use the version that matches each animal and give each of them a room.
All questions
