F3 and DAP are not interchangeable. The single most consequential decision when you build a calming product is which pheromone active goes into it — because the active determines the species, the behavioural claim, the delivery format and the regulatory story you are allowed to tell. This guide compares the two actives we supply most often and gives you a decision rule you can apply in under a minute.
What each active actually is
Feline Facial Pheromone (F3) is the fatty-acid fraction a cat deposits when it rubs its cheek against furniture, door frames and people. It signals familiarity and territorial security. Commercially it is supplied as a reconstituted fraction in ethanol, in which oleic acid typically accounts for 62–86% of the total fatty-acid content. It is the reference active for feline marking, scratching and environmental stress.
Dog Appeasing Pheromone (DAP) is a synthetic analogue of the inter-mammary pheromone secreted by lactating bitches, which signals reassurance to puppies and, in practice, to adult dogs in unfamiliar or stressful situations. It is supplied as an emulsion concentrate — commonly 2% w/w — with a droplet size distribution around D50 0.5–2 µm so it can be delivered cleanly from a spray or a plug-in diffuser. See the full DAP product introduction.
Side by side
| Feline Facial Pheromone (F3) | Dog Appeasing Pheromone (DAP) | |
|---|---|---|
| Species | Cat | Dog |
| Signals | Territorial security, familiarity | Reassurance, maternal presence |
| Typical use case | Marking, scratching, multi-cat tension, vet visits | Separation anxiety, travel, crate and kennel stress, noise |
| Common supply form | 2–10% ethanol solution | 2% w/w emulsion concentrate |
| Best formats | Spray, wipe, diffuser liquid | Plug-in diffuser, spray, collar |
| Key spec to agree | Fatty-acid fraction profile | Droplet size + emulsion stability |
Where buyers get this wrong
- Treating them as one “calming pheromone”. A cat product built on a dog active will under-perform and may fail a review panel. Species mismatch is the most common formulation error we see in incoming briefs.
- Ignoring the carrier. Both actives are volatile. Without a slow-release carrier, a diffuser can lose most of its payload in the first week — see slow-release carriers.
- Claiming too much. Position the product as behavioural support, not a medicine. Wording that implies treatment of a condition will stall in most markets; see our Resources page for compliant claim language.
The decision rule
Name the species first, then the behaviour, then the format. If the species is cat, start with F3; if dog, start with DAP. Then let the format choose the carrier, not the other way round. If your SKU has to serve both species, you need two formulations — there is no honest single-active compromise.
