Feliway - Classic Diffuser

TL;DR: The Feliway Classic Diffuser is a plug-in device that releases a synthetic copy of the feline facial pheromone to help cats feel calm at home. This starter kit includes the diffuser head and a 48 mL refill, covers up to 700 sq. ft., and lasts up to 30 days per refill.

Cats mark safe spaces by rubbing their cheeks on furniture, leaving behind a facial pheromone. The Feliway Classic Diffuser mimics that same pheromone to help your cat settle into her environment and feel at ease.

This is the starter kit, so you get everything you need to begin: the electric diffuser unit plus one 48 mL refill vial. It's a straightforward plug-in — no batteries, no app, no setup beyond choosing an outlet.

Who is it for?

The Feliway Classic Diffuser is for cat owners dealing with stress-related behaviours such as urine spraying, scratching furniture, or hiding. It's also useful in common transition moments: bringing a new cat home, moving house, introducing a baby, or managing tension in a multi-cat household.

If your cat is generally confident and not showing signs of stress, you likely don't need it. If she is, the Feliway diffuser is one of the most widely used calming tools in Canada for good reason.

How do you use the Feliway diffuser?

Screw the 48 mL refill vial into the diffuser head, then plug the unit into a power outlet in the room where your cat spends the most time. Leave it plugged in continuously — the pheromone diffuses gradually and works best with uninterrupted use.

Keep the diffuser upright, away from under furniture, curtains, or behind doors so airflow isn't blocked. Replace the refill every 30 days, and plan on replacing the diffuser head itself periodically per the manufacturer's guidance. For larger homes, use one unit per 700 sq. ft. zone.

How long until it works?

Many cats respond within the first 7 days, but full effect is typically seen after about 4 weeks of continuous use. For ongoing situations — like chronic multi-cat tension — keep the feliway classic diffuser running year-round with fresh refills.
