I was sceptical but our boy Oscar has completely changed. He used to spray the hallway every night and now he sleeps on the sofa with us. Three weeks in and the smell is gone. Worth every penny.

Frequently asked questions
My cat is peeing outside the litter box. Where do I start?
See your vet first to rule out a medical cause. Once that is done, stress is the next thing to look at.
Will this work for my cat?
No product works on every cat. That is why you get 90 days: if nothing changes, send us one email and we will make it right.
When will I see a change?
Some cats settle within days. Most change gradually over the first few weeks, well within your 90-day guarantee.
How many diffusers does my home need?
One diffuser covers one room, because the signals do not pass through walls. Most homes need two, and multi-cat homes usually need three or more.
How long does a kit last?
Each kit has 1 diffuser and 2 refills. Each refill lasts 30 days, so a kit gives you 60 days in one room.
Is it safe to leave plugged in all the time?
It is built to run around the clock. As with any plug-in device, do not use a damaged unit and keep it clear of anything flammable.
How does the 90-day guarantee work?
Your 90 days start the day it arrives. If the tension does not ease, email us and we will make it right.

We have two cats and the younger one kept hiding behind the boiler. Plugged this in near the kitchen and within a fortnight she was back on the windowsill. No more chasing her out at bedtime.
Bella and Milo used to scrap at the food bowls every morning. I put a diffuser in the kitchen and one in the lounge and they eat side by side now. Genuinely surprised.
Moved house last month and Luna would not leave the utility room. Plugged this in on day one and by Saturday she was on my lap again. Took longer for the upstairs but it is getting there.
My elderly cat started peeing outside the box after we got a kitten. The vet said stress. Put one of these in each room and within two weeks the accidents stopped completely.
I run a four-cat household and mealtimes were chaos. Hissing, swatting, someone always hiding. Three diffusers later and they queue politely. My partner did not believe it until he saw it.
Our rescue came home terrified of everything. She hid under the bed for days. Plugged this in and she slowly came out. A month later she greets us at the door. Cannot recommend enough.
Whiskers has been fighting with the neighbour's cat through the window. Since the diffuser he barely reacts. Not perfect but a massive improvement and no weird smell in the room.
My cat scratched the new sofa raw within a week of moving in. Nothing worked until this. One month and the scratching has almost stopped. He seems properly settled for the first time.
Had tried sprays, treats, even a behaviourist. This is the only thing that actually calmed my anxious boy down. He purrs on the bed now instead of hiding under it.
Two diffusers for a two-bed flat and the difference was obvious within a week. Both cats stopped overgrooming and the bald patches are growing back. The vet was impressed.
Takes a couple of weeks to notice anything so be patient. But once it kicked in my cat went from spraying the front door every day to maybe once a fortnight. Getting another for upstairs.
We adopted a second cat and the first one stopped eating. Vet said stress. Plugged this in and within ten days she was back to normal. Now they nap together on the radiator bed.
My old girl is 14 and started yowling at night. Since the diffuser she sleeps through and so do we. Absolute game changer for our household.
Tried every brand on the shelf and this is the first one where I actually saw a change. No mess, no daily routine, just plug it in and forget about it. My cat is calmer and I am calmer too.
