Pheromone plug-in diffusers are a bit like electronic air fresheners that plug into a wall socket, but instead of wafting around essential oils they release synthetic versions of the feel-good cat pheromones. The drug-free, odourless vapour creates a calm and peaceful environment for cats. Out of the countless chemicals that cats produce, the feline facial pheromone is the one that provides a sense of comfort, safety and reassurance to your cat - it sends out happy signals.
