Comfort Zone Calming Diffuser
For Cats & Kittens

Comfort Zone Calming Diffusers contain 2X more calming pheromones vs. competitors. Our Calming Diffusers release a drug-free vapor for up to 30 days that mimics a cat's natural calming pheromones to create a calming environment which helps reduce your cat's stress response behaviors like destructive scratching and urine marking.

The new Comfort Zone® Opticalm Diffuser releases a drug-free vapor that mimics your cat's natural calming pheromones, helping your cat feel safe, happy and calm. By sending signals in your cat's own language, this calming aid for cats can help reduce stress and unwanted behaviors like urine marking and scratching.

This new plug-in diffuser uses our same trusted pheromone formula with a sleek, modern design. It optimizes precious outlet space by leaving the bottom outlet open for other devices and features a plug that rotates 90 degrees for ease of use.

The team who brings you Comfort Zone® products takes your cat's "e-meow-tional health" seriously. Most cats will show improved behavior after two weeks or less with the diffuser's calming vapors.

How to Calm a Cat

Use the Opticalm™ Diffuser as part of an overall stress-relief strategy for your kitty. After you've plugged in the diffuser, set up cat trees in your home, giving your kitty tall spaces to own. Play lots of games with your cat, like chasing feather wands. Then offer plenty of treats and a warm lap whenever your cat wants to snuggle close.
