FELIWAY Optimum Cat Calming Pheromone Diffuser Kit

Why you'll love it

If your cat is scratching the furniture, spraying in corners, or staging WWE matches with your other cats, FELIWAY Optimum is the science-backed solution you've been looking for. This plug-in diffuser releases a patented blend of calming pheromones that help your cat feel safe, settled, and stress-free — no prescription required.

Product Description

FELIWAY Optimum is the newest and most advanced pheromone discovery from the brand that's been studying feline stress for 25+ years. It goes further than previous formulas — helping with more signs of stress in more situations than ever before.

We're talking scratching, urine spraying, tension and conflict between cats, general anxiety, and reactions to household changes. Whether you've just moved, brought home a new pet, or your cat simply decided today is a bad day — FELIWAY Optimum has your back.

In surveys, 93% of cat owners reported enhanced calming when using FELIWAY Optimum. That's a pretty convincing number.

The heated diffuser works continuously for up to 30 days and covers up to 700 sq ft. For larger rooms, simply add another diffuser. Plug it in where your cat spends the most time — or where kitty conflicts happen most. Keep it away from shelves, curtains, doors, or hallways for best results.

Interesting Points

A New Pheromone Discovery

FELIWAY Optimum uses a newly patented pheromone blend — not a rehash of older formulas. It's specifically designed to address more stress triggers than before, making it the most complete calming solution in the FELIWAY lineup.

93% of Cat Owners Saw Results

That's not a typo. In owner surveys, 93% reported enhanced calming for their cats. If you've tried other solutions and felt like you were talking to a wall, this one has real backing behind it.

30 Days of Continuous Calm

One refill, one diffuser, one month of peace. The heated diffuser disperses pheromones constantly so your cat is getting steady calming signals — not just a quick hit when things get hairy.

25+ Years of Feline Expertise

FELIWAY isn't a newcomer to cat stress. This product is built on decades of research into how cats communicate and feel safe. You're getting the benefit of all that science in a simple plug-in device.
