FELIWAY Optimum 30-Day Calming Refill

Why you'll love it

If your cat is scratching the furniture, spraying corners, or picking fights with the other cats, this isn't a personality problem — it's stress. FELIWAY Optimum uses a patented pheromone discovery backed by 25+ years of feline expertise to send calming messages your cat actually understands.

Product Description

FELIWAY Optimum is the brand's most advanced calming solution yet. This 30-day refill works with a heated FELIWAY Optimum diffuser to continuously release calming pheromones throughout your home — covering up to 700 sq ft of space. That's a lot of square footage between your cat and their next meltdown.

The formula helps reduce the most common stress signs: scratching, urine spraying, tension between cats, general fears, and reactions to changes in the home. And it's not just marketing talk — when surveyed, 93% of cat owners reported enhanced calming when using FELIWAY Optimum.

Plug the diffuser into the room where your cat spends the most time, or wherever cat conflicts happen most often. Avoid plugging it under shelves, behind curtains, or near doors, as this can reduce effectiveness. Also skip the hallway and the litter box room unless that's genuinely where your cat hangs out the longest.

For best results, replace the refill every month and swap out the diffuser head every six months. This refill is compatible ONLY with the FELIWAY Optimum diffuser — do not mix with other brands or other FELIWAY product lines.

Interesting Points

Patented Pheromone Science

This isn't just a rehash of old calming formulas. FELIWAY Optimum is a new patented pheromone discovery — developed specifically to address more signs of stress in more situations than previous FELIWAY products.

93% of Cat Owners Saw Results

That's not a small sample of cat lovers being polite. Nearly all surveyed owners reported enhanced calming. If your cat is stressed, those are pretty encouraging odds.

Covers a Full 700 sq ft

One refill + diffuser covers up to 700 sq ft — enough for a generous living room or bedroom setup. Running a bigger space? Just add a second diffuser.

Set It and (Almost) Forget It

Plug it in, let it run for 30 days, swap the refill. Monthly maintenance is minimal — and the payoff is a noticeably calmer household for you and your cats.
