Feliway is a manmade version of the odourless pheromone normally left by cats when they rub against objects in their environment. This pheromone is usually released by your cat when he or she feels happy or content and is also used to mark territory. When used correctly feliway can help to reduce your cats stress levels and combat marking behaviours like scratching or spraying. Feliway can be used around the home by spraying on prominent areas like window sills, cat flaps and doorways. For spraying or scratching, spray the area that has been marked after it has been thoroughly cleaned. To alleviate travel stress simply spray inside the carrier or car. Safe for cats of all ages. Wait 15 minutes before allowing your cat near any sprayed areas. Do not spray Feliway directly onto your cat. Ingredients: F3 fraction of Feline Facial Pheromone Analogue 10% Ethanol 90%.
