TheraPet Diffuser is your hassle-free solution for calmer, happier cats. It releases a natural, calming scent—called pheromones—that only cats can detect. These pheromones are like comforting messages, telling your kitties, "You're safe and loved."

TheraPet helps reduce stress-driven behaviors like scratching and marking, giving your home—and your cats—a sense of peace. It's like whispering soothing words to your furry friends, all day, every day.

Setup is quick—after that, TheraPet runs on autopilot.

  • Pick an open outlet in your cat’s favourite room
  • Twist the refill vial into the diffuser until snug
  • Plug in and leave running; replace the vial every 30 days for continuous calm

A unique pheromone blend you won’t find in any other diffuser.

  • Combines pheromone signals for a broader calming effect
  • Delivered in a plant-based carrier—no added fragrance or alcohol
  • Heat-controlled diffuser ensures steady, even release for 30 days

Keep the calm constant and spend less while you’re at it.

  • Up to 59 % off every automatic refill
  • Fresh vial ships right as the previous one empties
  • Pause or cancel anytime with a single click

FREQUENTLY ASKED QUESTIONS

Most notice a difference within a month, but results vary depending on the cat and their stress levels.
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.
Since pheromones are species-specific, you don’t have to be worried about dogs, other animals or humans being affected by the TheraPet diffusers.
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!
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.
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!)
