Description

PHERALO Cat Calming Diffuser Kit is a simple plug-in routine designed to help create a familiar, reassuring environment for cats at home. Continuous use can support cats during urine spraying, hiding and fear, furniture scratching, tension between cats, visitors, moving and other changes in routine.

Keep the diffuser running continuously in the room your cat uses most and follow the included product directions. Every cat is different, and results can vary.

How it Works

Setup is quick, and the diffuser then supports a consistent home routine.

Unplug the diffuser and remove the empty vial.
Insert a matching PHERALO refill and twist until secure.
Keep the unit upright, plug it into an open wall outlet and leave it running.
Replace the refill approximately every 30 days.

How long will it take to notice a change?

Every cat is different. Keep the diffuser running continuously and allow time for the home signal to become familiar. Some households notice early changes sooner, while others need several weeks of consistent use.

Where should I use the diffuser?

Place it upright in an open wall outlet in the room where your cat spends the most time. Do not cover it or hide it behind furniture, and follow the clearance guidance included with the product.

Will people or other pets in my home be affected?

PHERALO is designed as a non-sedating, odor-free home routine for cat households. Use it only as directed, review the complete product label, and ask your veterinarian if your pet has a specific health condition or sensitivity.

Is a light scent normal?

A faint product scent may be noticeable close to the diffuser. If you notice a strong or unusual odor, excess heat or damage, unplug it and contact PHERALO support before using it again.

Should I unplug the diffuser at night?

For a continuous routine, keep the diffuser plugged in day and night as directed. Always keep it upright and follow the safety instructions supplied with your PHERALO kit.

How often should I replace the refill?

Each refill is designed for approximately 30 days of continuous use. Replace it when empty, and consider a subscription if you want matching refills delivered automatically.
