What the Hush Diffuser is.
The Hush Diffuser is a plug-in device that releases a synthetic copy of the feline facial pheromone — the same signal a cat leaves behind when it rubs its cheek against a doorframe or a chair leg. To a cat, that scent marks a place as already checked, already safe. A diffuser fills a room with it continuously, which is why pheromone therapy is a standard first recommendation for situational anxiety in cats.
What separates Hush from the diffusers that came before it is concentration. The category standard has sat at roughly 2.0% since the late 1990s. Hush is formulated at 3.1%. A room therefore reaches a therapeutic level of saturation substantially faster, which is the entire reason Hush can talk about an effect within the hour while conventional diffusers ask for a four-week loading period.
That difference matters most in exactly the situations cat owners actually face, because those situations rarely give four weeks' notice. Fireworks start tonight. The carrier comes out this afternoon. The removal van arrives on Saturday. A diffuser that needs a month of continuous use before it does anything is not much use on any of those days.
Hush is designed for noise-triggered and situational anxiety — fireworks and thunderstorms, visitors, vet trips, travel, house moves, and the arrival of a new pet or baby. It is non-sedating: a cat on Hush still plays, eats, and behaves normally. It simply does so without the anxiety spiral.
Concentration, measured.
Pheromone concentration is the variable that governs how quickly a room reaches an effective level. Here is how Hush compares with the category standard.
A 3.1% formulation carries 55% more pheromone per unit volume than a 2.0% formulation. Coverage: whole-home with a two-pack. Refill life: 30 days of continuous use. Formulated with veterinary input.
How it works.
Three steps, no assembly, no app.
Plug it in
Into any socket in the room where your cat spends most of its time. The unit reaches operating temperature in about 90 seconds.
Give it an hour
The blend disperses and the room saturates. For a known event — fireworks, a vet appointment — plug in 60 to 90 minutes beforehand.
Leave it running
Pheromone therapy works continuously, not in doses. One refill covers 30 days; replace it when the bottle empties.

Common questions.
What is the Hush Diffuser?+
The Hush Diffuser is a plug-in calming pheromone diffuser for cats. It releases a synthetic analogue of the feline facial pheromone at a 3.1% concentration — 55% more than the 2.0% category standard — which allows a room to reach an effective level of saturation in about an hour rather than over several weeks.
How quickly does it work?+
Most cats show visible calming behaviour within 60 minutes: softer body language, slower breathing, less hiding. The full effect settles in within 24 hours. For a known trigger such as fireworks or a vet appointment, plug the unit in 60 to 90 minutes ahead.
How is it different from Feliway and other diffusers?+
Concentration and onset time. Conventional diffusers use roughly a 2.0% formulation and recommend four weeks of continuous use before results. Hush uses 3.1%, reaching therapeutic saturation faster, which is why it can be used reactively for a specific event rather than only as a long-term background measure. Hush also has a lighter, less chemical scent profile, and each refill is specified to last the full 30 days.
Is it safe around children, dogs and other pets?+
Yes. The formulation is non-toxic and intended for normal household use around dogs, children and people with mild scent sensitivities. Feline pheromones are species-specific, so the signal means nothing to a dog or a person. As with any wellness product, speak to your vet first if your cat has an existing health condition.
Will it sedate my cat?+
No. Hush is not a sedative and contains no drug. It works on the cat's sense of environmental safety, not on its nervous system directly. Cats continue to play, eat, groom and behave normally — without the anxiety response.
How long does one refill last?+
A full 30 days of continuous use. If a refill runs dry early, we replace it free of charge.
How much area does one diffuser cover?+
One unit covers a typical room and the space immediately connected to it. For whole-home coverage, or for a home over one floor, we recommend a two-pack with one unit per floor.
What if it does not work for my cat?+
Email us within 60 days for a full refund, and keep the product. Pheromone therapy does not work for every cat, and we would rather refund you than argue about it.
