A chemical signal animals use to talk to each other, a language of molecules instead of sounds. The ones in Sniffuser are comfort signals: messages that mean this place is safe. Humans don't have the receptors for them, which is why you'll never smell or sense a thing.

Dogs and cats each produce a well-studied calming signal, nursing dogs release an appeasing pheromone for their puppies, and cats mark trusted territory with a facial pheromone when they cheek-rub. Synthetic copies of both have been researched in veterinary behavior science for decades. Sniffuser warms those copies into the air, one species per formula. It's support built on established biology — not magic, and we won't pretend otherwise.

Yes, genuinely different, not different labels. The dog formula is a synthetic analog of the canine appeasing pheromone; the cat formula is an analog of the feline F3 facial pheromone. Each species only carries receptors for its own signal, so buy the one that matches your animal.

The signals are species-specific, human noses and human brains simply don't register them, at any age. The device itself is a low-heat plug-in that runs about as warm as a nightlight; treat it like any electrical appliance and follow the enclosed instructions.

The dog signal is read by dogs, the cat signal by cats, other species don't carry the receptors, so your parrot or hamster gets nothing but the same clean air. No formula changes are needed for a multi-pet home.

Both, honestly, one of each, in the rooms where each pet spends their time. The two signals don't clash or mix: your dog can't read the cat's message, and vice versa.

No, and for cat homes that's worth saying twice, because many essential oils are genuinely unsafe around cats. Inside the vial: a synthetic pheromone analog in a cosmetic-grade carrier oil. No fragrance, no alcohol, no oils.

No. Nothing is ingested and nothing acts on the body the way a sedative does, the room just starts reading as safer. Your pet stays fully themselves, with the volume turned down.

A calmer room generally helps recovery, and there's nothing to swallow or apply. That said, recovery is your vet's territory, if they've given instructions, those win. When in doubt, ask them first.

The diffuser doesn't add anything to your pet's body, so it typically sits fine alongside other support. But medication plans belong to your vet, run it past them, especially for behavioral meds.
