Feliway contains the same pheromone released by cats when they rub their face against objects, which they do when they are feeling happy and relaxed. Even small changes can upset your cat and prevent them from leaving this pheromone, which in turn makes them feel less secure, and increases their stress. Stress can lead to unhappy behaviour such as less interaction with you, hiding away, general mischief or even scratching or spraying.
Feliway is recommended for cats spraying, scratching or hiding inside. Feliway is also recommended for use in stressful times such as redecorating, moving home, visiting the vet or cattery or travelling.
