Using the Feliway MultiCat 30-Day Starter Kit to help your cats live happily and in harmony? Use the Feliway MultiCat 30-Day Refill to quickly, easily refill your diffuser and continue providing room-wide pheromone therapy. Refill cartridge contains clinically proven synthetic cat appeasing pheromone that mimics the natural pheromone a mother cat produces when kittens are born. This pheromone reduces tension between cats and ultimately promotes a happier, more harmonious home.
Used in the Feliway MultiCat diffuser, the Feliway MultiCat 30-Day Refill helps curb your cats' stressful responses to cat conflicts and introducing new cats/kittens. The synthetic cat appeasing pheromone formula contained in the convenient Feliway MultiCat 30-Day Refill cartridge communicates a reassuring message to your cat, which helps control unwanted behaviors including tail twitching, standoffs, stalking or chasing, biting, hissing, growling, spitting, or fleeing from housemate cats. Noticeable results typically occur within 7 days.
Replace your refill cartridge every 30 days. If you need a new/additional diffuser, purchase the Feliway MultiCat Starter Kit. Feliway MultiCat Refill and Feliway MultiCat Diffuser designed to work exclusively with one another; do not attempt to use another diffuser with the refill cartridge and vice versa.
