Frequently Asked Questions
How long until I see results?

What if it doesn't work for my cat?
We offer a 60-day money-back guarantee. If you don't see improvement within 30 days of continuous use, contact us for a hassle free refund.
Is it safe for kittens, seniors, and multi-cat homes?
Is it safe for kittens, seniors, and multi-cat homes?
Yes. VetCalm is veterinary-grade and safe for cats of all ages. Safe for homes with multiple cats, dogs, and other pets. Pheromones are species-specific - only cats detect them.
Where should I place the diffuser?
Where should I place the diffuser?
Plug into an outlet in the room where your cat spends most time or exhibits stress behaviors. Keep away from air vents, windows, and doors to prevent pheromone dilution. DO NOT use power strips or surge protectors - this reduces effectiveness. One diffuser covers up to 700 sq ft. For cats with behaviors in multiple areas (spraying in bedroom, scratching in living room), you'll need one diffuser per problem zone - our multi-pack bundles save up to 30% vs. buying separately.
Should I unplug it at night?
Should I unplug it at night?
No. Keep the diffuser plugged in 24/7 for continuous pheromone release. Turning it off interrupts the calming effect and delays results.
How often do I replace the refill?
How often do I replace the refill?
Replace the refill vials every 30 days or when liquid runs out to maintain continuous pheromone coverage - any gap in usage can allow stress behaviors to return. Replace the plug-in unit itself every 6 months or after using 3 refill vials (whichever comes first) to maintain optimal diffusion. Our bundle packages coupled with our subscription auto-delivers refills on your schedule so you never run out, and saves you time and money per refill compared to one-time purchases.
Will dogs or people be affected?
Will dogs or people be affected?
No. Feline pheromones are species-specific and undetectable to humans and dogs.
Can I use it in multiple rooms?
Can I use it in multiple rooms?
For best results, use one diffuser per room where your cat exhibits stress behaviors. Each unit covers up to 700 sq ft. Multi-cat households often need 2-3 diffusers for full-home coverage - check our multi-pack bundles for the best value vs. buying separately. For long-term behavioral stability, subscription is the recommended approach - pheromone therapy requires consistent 24/7 coverage without interruption. Running out between refills allows stress behaviors to return. Our auto-delivery subscription ensures your cat maintains calm behavior permanently while saving you money per refill.
Is there a smell?
Is there a smell?
You may notice a faint odor when the unit first heats up - this is normal. The pheromones themselves are odorless to humans. If you notice a strong smell, contact us for troubleshooting.
