Your cat's body heat activates the pheromones in the collar. The pheromones mimic a cat's feline facial peromones (FFP). It's the same pheromone a cat would leave when head bunting you or rubbing their face on furniture. It's a pheromone that says, "this object is safe and familiar". So, using the collar takes the feeling of home on the go. Supports cat's well-being by controling stress responses.
For use on cats older than 10 months.
