Why pet parents choose SoothePaws

1. Continuous coverage

Each refill delivers 30 days of feline pheromone signal so your cat's territory stays marked as safe.

2. Cheapest on Subscribe

Subscribe and save up to 17%. Skip, pause, or cancel anytime.

3. Multi-cat ready

Stay calm. Never restart.

The science, simply

Feline Facial Pheromone (F3) only works when consistently present. The moment the diffuser runs dry, your cat's nervous system stops receiving the safety signal and territorial stress can return.

Keeping a fresh refill in your diffuser is the difference between a stable, settled cat and one that re-experiences anxiety every few weeks. Subscribe and we deliver before you run out.

Odorless to humans, safe for all pets.

Cat pheromones do not affect dogs or other species.
