Product Description

Living with cats who can't stand each other is exhausting — for you and for them. FELIWAY MultiCat works by mimicking the natural feline appeasing pheromones that cats produce, sending what FELIWAY calls "harmony messages" throughout your home. Translation: your cats get a subtle, invisible signal to chill out and coexist.

Signs of tension between cats — chasing, blocking doorways, staring contests, hissing, or outright fighting — can all be addressed with consistent use. Each refill lasts up to 30 days, and each diffuser covers up to 700 sq. ft., making it a solid option for most rooms where your cats hang out.

This 3-pack gives you a full 90-day supply. Just a heads-up: the diffuser head is NOT included — this is a refill-only set. Plug your diffuser into an outlet in the room your cats use most, keeping it upright and away from curtains or furniture that could block coverage. Replace refills every 4 weeks and swap out the diffuser head every 6 months for best results.
