FREQUENTLY ASKED QUESTIONS

How long will it take to see results?

Most notice a difference within a month, but results vary depending on the cat and their stress levels.

Where should I use the diffuser?

The plug-in should be used in rooms where your cats spend most of their time. Avoid using outlets that are under windows, near air vents, or close to doors, as drafts will impair the proper diffusion of the pheromones. DO NOT plug the diffuser into a power strip or surge protector. The vial should always be directly below the plug-in unit for proper diffusion and to prevent leakage. To ensure the vial is always below the plug-in unit, there is a swivel function on the prongs for outlets with horizontal orientations.

Will my dog or people in my home be affected by RosiePet?

Since pheromones are species-specific, you don’t have to be worried about dogs, other animals or humans being affected by the RosiePet diffusers.

Is the smell normal?

The pheromones are diffused when the plug-in unit heats up. As with any heating element, a slight smell may be present and is totally normal. If you find your diffuser has a stronger smell, please contact us and we will be happy to troubleshoot with you!

Should I unplug the diffuser at night?

To keep the good vibes flowing, you should keep your diffuser plugged in at all times. If you notice your diffuser collecting dust, please unplug and follow the cleaning instructions in the user manual found in every box.

How often should I replace the diffuser?

We recommend replacing the refill vial every 30 days or when the liquid runs out. The plug-in unit should be replaced after 6 months of use or after you have used three refill vials (whichever comes first!)
