It is a signal, not a character flaw.

- The vial that goes into the Stillroom diffuser when the first thirty days are up.
- Same pheromone, same thirty days. The device you already own keeps working.
- One vial per device. It screws in from below, so nothing about the routine changes.

What is in the box
Vials only — no base. Everything that works is in the vial.
How to use it
Replace the vial on day thirty even if you can still see liquid: the last few millilitres release far less than the first. Same device, same room.
Where this will not help
A refill does not fix a device that is in the wrong room. If nothing changed in thirty days, changing the vial will not change that either — write to us instead.
Shipping and returns
Ships from our US warehouse, arrives in 2–5 business days. Free shipping over the threshold shown at checkout. 30 nights, money back — write to hello@pheroniapets.com and you keep the diffuser.
Safety
Nothing is swallowed and nothing is sedated. Keep the vial out of reach of children and pets. Not a flea, tick or pest-control product.
Full description
An empty diffuser is a diffuser that has stopped working.
It runs out quietly. No light goes off, nothing beeps, the unit still sits warm in the socket. Two weeks later the marking is back, and the easiest conclusion to reach is that the thing never worked in the first place.
It worked. It ran out.
Why the refill matters more than the device
The base is a warmer. Everything that does the work is in the vial. The households that see a difference are almost always the ones that never let it run dry during the period that mattered: the weeks after the move, the first month with the second cat, the season of fireworks.
Set a reminder on the day you plug a fresh vial in. It is the cheapest thing you will do for this.
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 serves one diffuser in one room. It does not carry through the house.
- Two rooms means two diffusers and two vials running at once.
- The two-vial pack is the sensible default: one in the socket, one in the drawer, so the gap never happens.
Good to know
- Store spare vials upright and out of direct sun
- Do not top up or decant. The vial is sealed for a reason.
- Leave the base plugged in while you swap. It reaches working temperature faster.

Why it works
Three things nobody else tells you.
AI-generated image
AI-generated imageThe 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.
AI-generated imageThe 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.
Unplug and pull
Let the base cool for a minute, then pull the empty vial straight out. The base stays — you never replace that.
1 minute
Twist in the new vial
Hand tight, no tools. The cat vial goes in the cat device, the dog vial in the dog device.
30 seconds
Write the date somewhere
Day thirty is the swap, even if you can still see liquid — the last millilitres release far less than the first.
Day 3030days per vial
Day thirty
An empty diffuser is a diffuser that has stopped working.
Replace the vial on day thirty even if you can still see liquid — the last few millilitres release far less than the first. That is the day the corner comes back if nothing follows.

Where this will not help.
We would rather lose the sale than take it under a false expectation.
- An animal that stops eating, strains or changes suddenly needs a vet, not a new vial.
- Behaviour that started the week you changed food or litter is about the food or the litter.
- Too little space per animal stays tense, whatever the room smells like.
- A spot never cleaned with enzyme cleaner is still an invitation. Clean it first.
- A fresh vial does not fix a device standing in the wrong room. If thirty days changed nothing, move the device before you buy more liquid.

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

Living with it

One socket. Thirty nights. Nothing swallowed.
The evidence
What the research actually found.
Including the studies that found nothing.
These are independent studies of synthetic pheromone analogues as a category. They were not run on our product, and we do not claim their results as ours. We list them so you can read them yourself — the ones that worked and the ones that did not.
- 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. That is why the guarantee runs 30 nights.
Is it safe around children and other pets?
Nothing is swallowed and nothing is sedated. Pheromones are species specific — the version for cats carries no message a dog or a person can read. Keep the vial itself 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; if we ever miss that, we write to you and you can cancel.
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 with an ammonia-based one. Until the old mark is gone it is still an invitation. We do not sell the cleaner; any five-dollar bottle works.
Does it fit the diffuser I already have?
It fits the Stillroom base — the one that came with your diffuser set. It does not fit other brands' plug-ins: the thread and the wick are not standardised. 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. Two devices in two rooms beat one device in a hallway.
Goes with it
The refill keeps the room. For the carrier, that is the collar.
