Keep your kitty companion calm around the house and on-the-go. Each purchase comes with a 48-mL Feliway MultiCat 30 Day Starter Kit Plug-In Diffuser & Refill and a 60-mL bottle of Feliway Travel Spray On The Go Management Behavior Modifier Spray. These products create a synthetic copy of the feline pheromone from the mammary gland area after a mother gives birth to bond with kittens. By mimicking the cat’s natural pheromones, Feliway creates a state of calmness and comfort to alleviate tension and conflict between cats. The spray can be used in carriers on the way to the vet to calm nerves and soothe aggressive behavior, or even use it in the home to reduce scratching and spraying. It’s like breath of fresh—and familiar—air for your anxious kitty!
