Feliway is a copy of the pheromone that cats naturally rub around their environment to make them feel comfortable. It is odourless to us - but a potent calmer for cats. Every time a cat rubs the side of its face against objects in the home, it leaves behind a pheromone to mark its territory. This pheromone helps them feel at home and happy. Changes in and around your home can upset your cats and prevent them from following their normal routine of rubbing this pheromone around their area. They then feel less secure, and become stressed. Activities such as redecorating, moving the furniture, having guests or tradesmen in, going to the cattery and moving home remove these natural pheromones from around the cat and cause stress. Any change in your home organisation and schedule disturbs your cat, for example: a newborn baby, toddler or a new partner, a new work roster. Cats are very sensitive to routine and crave a stable environment. A stressed cat may hide, scratch furniture, urinate outside the litter box, spray the curtains or become aggressive to other cats in the household. Feliway helps maintain the scent that gives your cat a feeling of peace and calm, and reduces the stress that your cat is experiencing.
