Cat Calming Diffuser Kit
"So many everyday 'problem' behaviours in cats come from stress or fear, not spite. We built calmd to help your cat feel safe, so calm can come naturally."
🐾 The calmd team
A single shipment, no auto-renewal. Your kit arrives with 2 diffusers + 4 refills, enough for 60 days of calm, right out of the box.
then $34.99 per refill shipment, every 60 days
Kit now, refills forever
Your first order includes the full kit, 2 diffusers + 4 refills. After that, we automatically send 4 refills only (no more diffusers) every 60 days. Save 15% on every refill. Pause, skip or cancel anytime.
Most "problem" behaviour is a stressed cat asking for help the only way it knows how. calmd fills the room with a pheromone your cat reads as reassurance, so the scratching, hiding and litter box stress ease up not because your cat was corrected, but because it finally feels safe.
No app, no timer, no daily routine to remember.
Wherever your cat camps out most, living room, cat tree corner, laundry. That's the spot.
Click a fresh vial into place, you'll feel it seat properly. No priming, no setup.
Leave it running around the clock. Swap vials at day 30 for a full 60-day cycle.
Psst, that's Waddle. Our diffuser head is shaped just like him.
A gentle, drug-free formula designed to help your cat feel settled and secure.
Real feedback from cat parents using the calmd diffuser kit.
Ella + Luna
Luna used to scratch the door frame every morning. Two weeks with the diffuser in the hallway and that habit has almost completely stopped.
Tom + Biscuit
Biscuit is so much calmer.
Grace + Willow
We have three cats and Willow was always the anxious one. Since plugging this in near her favourite spot, she's out and about so much more.
Ben + Momo
Momo naps in the open now.
Zara + Ziggy
Moving house was stressful for Ziggy and he hid for days. This time round with the diffuser running before the move, he settled within 48 hours.

Easy to set up and use.

Stress starts to lift, fewer litter box issues, less scratching, calmer days.

Confidence builds, less hiding and less reactivity to household changes.
3+ MONTHS
The new normal, calmer and more adaptable, day to day.
No sedatives. No stress. Just a gentle daily assist.
No sedatives, no synthetic fillers, just a plant-based carrier and a pheromone.

Ask Waddle: still unsure? Reach out, a real person on our Aussie team will answer.
Yes. The diffuser releases a cat-appreciable pheromone at a low, steady concentration, it isn't a medication or a scent additive for humans, and it's not known to affect dogs, though it's formulated for cats specifically. As with any small appliance, keep it out of reach of curious kittens and toddlers.
One diffuser covers one average room regardless of how many cats share it, so a multi-cat household usually just needs the same room-by-room coverage as a single-cat home, most owners start with our 2-diffuser bundle for a living area plus a bedroom.
A cat-appreciating pheromone, a naturally occurring blend of fatty acids, carried in a gentle plant-based solvent so it diffuses steadily into the air. No sedatives, no synthetic medication.
It's gradual, not instant. Most owners notice fewer stress signals, hiding, scratching, litter box avoidance, within the first 2 to 4 weeks of continuous use, with steadier improvement over 60 to 90 days.
The room your cat spends the most time in, away from vents, windows and doorways where draughts can disperse the pheromone before it fills the space. Skip power boards, plug directly into the wall.
You can, though the diffuser needs a wall outlet to run, so it suits a hotel room or a relative's house more than the car. Many owners keep a second unit specifically for trips.
