Somewhere between the second litter box and the second bottle of enzyme cleaner, you started feeling something you did not expect. Frustration with an animal you love, and then guilt about the frustration. That is the part Cat Parents do not say out loud.
Your cat is not being bad. Your cat is stressed. Those are two completely different problems, and only one of them has an answer you can plug into the wall.
The three situations Cat Parents write to us about
I just replaced the rug and I can still smell it, and I do not know how many more times I can do this.Marking and accidents in a cat who is physically well and simply does not feel safe in the room any more.
She has been under the bed since the storm rolled in on Tuesday, and she will not eat while she is under there.Hiding and noise fear, where the cat you love is somewhere you cannot reach.
I lie awake listening for the yowl, because if I do not get up they will be at each other again.Multi cat households, where the trouble is a hallway rather than a cat.

Tell Me About:
“Most of what Cat Parents describe to me is not a difficult cat. It is a cat whose home has stopped feeling predictable, and the behavior follows the feeling. A calming pheromone speaks to exactly that. It is a synthetic copy of the reassuring signal a cat leaves when it rubs its cheek on a doorway, so the room reads as familiar and claimed again rather than uncertain. CalmGuard is drug free and non sedating, so it supports calmer behavior while your cat stays entirely themselves.”

StepWhat to do
1Unbox the diffuser and take the cap off the first of your three refills
2Screw that first refill into the diffuser. The other two are months two and three
3Plug into a wall outlet, in the room your cat actually lives in
4Leave it running continuously
5Swap in the next refill every 30 days. Three refills is 90 days
One diffuser covers up to 700 sq ft. Sit it in an open area of the room your cat actually lives in, roughly 3 to 4 feet above the floor, never behind furniture or curtains. Allow 24 to 48 hours for the room to reach a steady level, then look for changes over the first 7 to 14 days.
And the calming collar
Thread the band through the two small silicone keeper loops and set the length on the ridged section.
Check the fit. Snug enough that a paw cannot catch under it, loose enough to slip two fingers underneath.
Put it on for the trips that leave the room the diffuser covers, the carrier, the car, the vet visit, a new room or a move. Take it off again at home.
It is breakaway. There is no buckle and no clip to unfasten: the band itself parts under a little tension, so it lets go if it snags.

The real reasons
Why your cat will not settle
It is almost never defiance. A cat who sprays, hides, yowls at the ceiling at 3am or quietly stops using the litter box is telling you the room does not feel safe. You have already added a box, changed the litter and bought the enzyme cleaner twice. This is the part nobody explains. Pick where your home struggles, open each reason, and see which half of the CalmGuard kit supports it.
Two things move a litter box problem and you need both of them. The practical fix first: one box per cat plus one, in separate quiet rooms, never beside the food and water bowls, unscented litter about two inches deep, scooped every day. A hooded box can feel like a dead end to a cat who is already worried about being cornered. Then the part the boxes cannot do. A cat who has been anxious in that room does not relax the day the litter changes, and the room still has to start reading as safe again. Plug the diffuser in while you make the changes so both halves happen at once. Boxes are the practical half. The pheromone is the half that changes how the room feels, and it is the half most Cat Parents never get to. Give it one full 30 day refill alongside the new setup, and the 60 Day Calm Home Guarantee carries the risk while your cat settles.
Supported byThe plug in diffuser, in the room the boxes live in
Once the boxes are right, the diffuser helps the room around them read as familiar and safe again, which is the part stress had been taking away.
Spraying looks nothing like squatting. A cat backs up to a wall or a door frame, tail quivering, and leaves a small amount high up. That is territory language rather than a lapse in house training, and it usually spikes when something changed. A strange cat at the window, a house guest, a move, a rearranged living room. Do the practical thing first: put the furniture back if you can, and block the view of the outdoor cat with a strip of frosted film on the lower pane. Then give the corner itself a reason to feel settled, because a cat only redraws a border that has stopped feeling certain.
Supported byThe plug in diffuser, at the corner that keeps getting marked
A calming pheromone is a synthetic version of the friendly signal a cat leaves when it rubs a doorway, so the corner already reads as claimed and settled before your cat feels the need to say it again.
A cat who gets ambushed on the way to the litter box will quietly give up the trip. So will a cat who has to walk past a dog bed, a washing machine that starts without warning, or a doorway another cat guards. The problem is often the route rather than the box. Give every box a clear line of sight and two ways out, then watch who walks past whom for a couple of evenings. Opening the route removes the reason to avoid it. Calming the room removes the memory of it, and a cat who has been ambushed at that doorway for six months needs both.
Supported byThe plug in diffuser, at the chokepoint where the standoffs happen
With the route opened up, the diffuser supports a calmer room at the pinch point, so the walk to the box stops being a negotiation.
Two cats under one roof are not automatically a social group. Cats who grew up apart often tolerate each other rather than bond, and tolerance needs room to work. When the space is tight, every doorway and every stair turns into a negotiation, and the cat who keeps losing that negotiation starts guarding instead of resting. Give them more room to work with, and give both territories the same calm signal, because the truce is only as good as the worst room in the house.
Supported byOne diffuser per floor, in the rooms they actually share
Coverage is up to 700 sq ft per diffuser, and a diffuser only ever calms the space it is plugged into. Matching the number of diffusers to the home is what gives every shared room the same familiar signal.
Most tension between cats is silent long before it is loud. One cat sits in a corridor and simply does not move. Another gives up a water bowl, or waits until the house is asleep to eat. By the time there is yowling and fur on the carpet, the standoff has usually been running for weeks in a spot you walk past every day. Give that spot a second way through, a shelf or an alternative route, so the cat being blocked has somewhere to go. Then take the charge out of the spot itself, because a doorway that has been contested for a month does not stop being contested because you added a shelf.
Supported byThe plug in diffuser, at the doorway one cat has decided is not shared
Put it at the chokepoint. The route gives the blocked cat an exit, the pheromone gives the doorway a reason not to be worth guarding.
Food, water, litter boxes, beds and high perches are what cats compete over. Put them all in one place and you have built a queue. Multiply them, separate them, add vertical space, and give every corridor a second exit, and a lot of the guarding has nothing left to guard. That is half the job. The other half is the atmosphere the last few months built, and that is the half you plug into the wall.
Supported byThe plug in diffuser, once the layout has given them room
The layout removes the reason to guard. The pheromone supports the calmer mood that lets two cats sit in one room at a comfortable distance.
Moving house, a spare room suddenly in use, a new baby, building work next door, a rearranged living room. None of it is dangerous, and all of it wipes out the scent map your cat spent months laying down. Hiding, night calling and scratching are what that loss sounds like, and it usually shows up within a day or two of whatever changed. Keep one corner of the house exactly as it was if you possibly can, and lay a familiar signal back over the room your cat has retreated to.
Supported byThe plug in diffuser, in the room your cat retreats to, door left open
The diffuser puts a familiar signal back over a room that suddenly reads as unfamiliar, which is precisely what the change took away.
Loud, unpredictable noise arrives as sound, vibration and flashing light at once, and there is nothing a cat can do about any of it. Give them a covered spot, low down or high up, close the curtains, leave a familiar sound running, and never pull them out of the hiding place they chose. Let them come back out on their own clock. And set the room up in advance rather than on the night, because the room has to already feel calm by the time the first bang lands.
Supported byThe plug in diffuser, running well before the night starts
Allow 24 to 48 hours for the diffuser to reach a steady level in the room, so plug it in the week of, not the evening of. If you know a season is coming, leave it running through it.
A cat who is unsettled at home is usually worse inside a carrier. Leave the carrier out as furniture for a week before the trip and feed near it, so it becomes ordinary furniture rather than an ambush. Put the calming collar on before the door closes rather than in the waiting room. For moving day, plug in and collar up ahead of time rather than on the morning itself.
Supported byThe calming collar, for the carrier, the car and the vet visit
The collar is the away half of the kit, in every box at no extra cost, because calm should not end at the front door.
CalmGuard soothes the stress behind unwanted behavior. It is not a medicine and it does not diagnose any condition. Every reason on this page comes back to the same thing, a room your cat has stopped reading as safe, and that is exactly what CalmGuard puts back.
Your cat has been trying to make the room feel safe on their own
When a cat rubs their cheek on a doorway, they are leaving a signal that says this place is mine and it is settled. A stressed cat stops laying that signal down, and a room without it never stops feeling like somewhere to be watchful. CalmGuard puts that same signal back into the air, all day, in the rooms your cat actually lives in. Drug free, non sedating, and odorless to you.
Normally
Your cat marks the room as settled
Cheek rubbing is not only affection. Your cat is leaving a scent signal on the doorway, the chair leg and the table corner, and that signal is what tells them this room is theirs and nothing in it needs watching.
Under stress
Stress stops the signal going down
A move, a storm, building work or a new cat in the house, and your cat stops laying it. The signal fades off the room, nothing replaces it, and a place that used to read as settled starts reading as somewhere to stay braced.
With CalmGuard
CalmGuard puts the signal back in the air
The diffuser releases a synthetic copy of that same calming signal continuously, so the room carries it again even on the days your cat is too tense to lay it down. Your cat reads the room. You smell nothing at all.
What is actually in the air
2%synthetic feline calming pheromone, in a fragrance free carrier base
That is the whole formula. It is a signal your cat reads rather than a sedative that acts on your cat, which is why a cat can settle under it and still be completely awake.

CalmGuard soothes the stress behind unwanted behavior. It is not a medicine and it does not diagnose any condition.
The diffuser gently warms a sealed vial of synthetic feline calming pheromone and releases it slowly into the air. It is a synthetic version of the calming signal a cat leaves when it rubs its cheek on a doorway, designed to be read exactly the same way, so the space reads as familiar rather than contested. People cannot smell it at all. This is the same guide that ships on the card inside your box.

⏱
Give the room 24 to 48 hours, then give your cat two weeks
Allow 24 to 48 hours for the diffuser to reach a steady level in the room. That window is how long the room takes, not a promise about your cat. From there, look for changes over the first 7 to 14 days, and give it the first full 30 day refill before you judge it. A cat who has been braced for months does not unclench in a day. That window applies to tension, hiding, scratching and night calling. Leave the diffuser running and replace the refill every 30 days. The kit carries three refills, which is 90 days of continuous use, so the room holds while your cat settles.
Using it safely
Plug it straight into a wall outlet. Never an extension lead and never a multi way adapter
Keep it upright and uncovered, away from curtains, bedding and anything that can fall against it
Always leave the door open so your cat can move away from it. Never use it in a closed room, a crate or a carrier
Fragrance free with no essential oils, so nothing is added to the air to scent the room. Stop use if you notice coughing or wheezing
If you keep birds, plug it into a room your birds are not kept in, as you would with any plug in device
Two minutes to set up. 90 days of continuous use in the box.

What to expect
A calmer home, on a real timeline
The pheromone has to build in the room before your cat can read it, and a cat who has been braced for months does not unclench in a day. Here is the honest arc, and why the kit carries 90 days rather than two weeks.
First 24 to 48 hours
The room is filling
The diffuser warms the vial and the calming pheromone builds to a steady level in the room. Little visible change yet, and that is exactly what should be happening. Leave it running rather than switching it on and off.
Days 3 to 7
The first small signs
Cat Parents usually notice the small things first. A cat who comes out while the family is still in the room. A shorter standoff at the doorway. A quieter night than the one before it.
Days 7 to 14
The pattern starts to change
This is the stretch Cat Parents describe most often, and it is the window to judge by. Fewer flashpoints at the doorway, less time under the bed, a cat who settles somewhere in the open. Give it the first full 30 day refill before you decide.
Day 60 and on
Maintenance and the guarantee
Keep the diffuser running and swap the refill every 30 days so the room holds. If your home is not calmer, that is exactly what the 60 Day Calm Home Guarantee is for.
Results vary with the cat, the household, and how long the stress has been running. This reflects the typical Cat Parent reported arc, never faster. CalmGuard soothes the stress behind unwanted behavior. It is not a medicine. The kit carries 90 days of continuous use, which is comfortably past the point where Cat Parents tell us the room changed.
You have 60 days to decide. We only need the first two weeks.
What it helps with
Soothes the stress behind unwanted behavior
CalmGuard is built for the six behaviors printed on the box. Every one of them is a stress signal rather than a discipline problem, which is why the answer is a calmer room rather than a firmer hand.
๐ง
Peeing
Accidents outside the litter box, from a cat who is physically well and has simply stopped trusting the room.
โ๏ธ
Fighting
Standoffs, ambushes and the doorway one cat has decided is not shared.
๐ช
Scratching
Furniture scratching that is about tension rather than claws.
๐
Spraying
Territory marking indoors, on walls, doors and furniture corners.
๐๏ธ
Hiding
A cat who has been under the bed since something changed.
๐
Meowing
Night calling and restlessness in a house that will not settle, from a cat who cannot switch off long enough to sleep.
Built for the moments that set it off
A new environment
Loud noises and storms
Multi cat conflict
A new kitten or a new adult cat
Moving house
Building work next door
CalmGuard soothes the stress behind these behaviors. It is not a medicine and it does not diagnose any condition. Every one of these six is what stress looks like in a cat who is physically well, and every one of them is what CalmGuard is built for.
If two or more of those are happening in your house, start with 2 kits.

Home and away
Calm does not stop at the front door

At home
The plug in diffuser
Covers up to 700 sq ft of the rooms your cat actually lives in. Put it where the trouble starts, or in the room your cat spends most of the day in. Keep food, water and the litter box in separate places from each other, because a cat should not have to eat beside where they go.

+Away from home
The calming collar, in the box
The collar goes where a plug in cannot. It is a breakaway collar, and there is no buckle to unclip. The band itself parts under a little tension, so if it catches on a branch, a fence, a chair leg or a cat's own back foot, it lets go and your cat walks away. That release is the entire reason a cat can safely wear a collar at all. It is water resistant and it adjusts to fit. Two fingers should slide under it comfortably. Check the fit after the first hour, then weekly, and take it off if your cat grooms at it or the skin underneath looks red.
The carrier and the car
The vet waiting room
Moving day, from the old house to the new one
The cat who seems most on edge, wherever they go in the house
Everything in the box. One kit, both halves of the problem.
Most calming brands in this aisle sell you a plug in or a collar and leave you to buy the other one separately. Ours ship together. That is not a bonus. That is the whole point.
Both halves, one box, from $32.99 on Subscribe and Save.
Side by side
What you get that the aisle does not give you
Most cat calming diffusers sell a plug in on its own, print no room size, and leave you to work out whether the refill really lasted. CalmGuard publishes all three numbers and ships the collar in the same box.

Coverage, published
How much house one diffuser actually covers
One CalmGuard diffuser covers up to 700 sq ft, and it only ever calms the space it is plugged into. The signal does not travel through a closed door or up a stairwell. Most Cat Parents in this aisle are handed no room size at all, put a single unit in the living room, and then decide pheromones do not work. Size it to your home first and you skip that entire experience.
700sq ft covered by one diffuser
One room your cat uses, up to 700 sq ftOne kitA studio, or a cat that genuinely lives in one room.
Two rooms, or two floorsTwo kitsThis is where most homes land. One at the chokepoint where the trouble starts, and give that spot a second way through, a shelf or an alternative route. One in the other room your cats actually use. Two rooms is two diffusers.
Three or more rooms or floorsThree kitsOne diffuser in each room or floor your cat actually uses, up to three. Coverage is the variable nobody tells you to control.
What calm actually costs a day
$0.28a day, Subscribe and Save, 2 kits, first order
$0.37a day per kit, Subscribe and Save, every order after the first
$0.44a day, one time purchase, 1 kit
Compare that with what a tense house already costs you. Enzyme cleaner, replacement textiles, extra litter, and the evening you spend cleaning instead of sitting down.
Cost a day is the price divided across 90 days of use, per kit. The 2 kit and 3 kit figures are the introductory first subscription order. Subscription orders after the first are $32.99 per kit, so a 2 kit subscription is $65.98 every 3 months and a 3 kit subscription is $98.97 every 3 months. Skip, change or cancel any time.
Plenty of Cat Parents arriving here have already been disappointed by something in this aisle at least once. So we made being wrong free. Try CalmGuard for 60 days. If your home is not calmer, tell us anytime from day 30 and we will make it right.
Plug it in and allow 24 to 48 hours for the diffuser to reach a steady level in the room
Run it continuously and look for changes over the first 7 to 14 days
If your home is not calmer, email us any time from day 30 to day 60 after delivery
We make it right. No arguing, and nothing to send back
We are not going to tell you we are the exception. We would rather take the risk off you than argue with your experience.
And if the behavior has not shifted in 60 days, tell us your square footage and the rooms your cat actually uses before you give up on it. One diffuser calms up to 700 sq ft and only the space it is plugged into, so the commonest reason a home sees nothing is running one where it needed two.
The guarantee runs from day 30 to day 60 after delivery, one claim per household. Day 30 is one refill in, which is long enough to tell. Contact us inside that window and we will take it from there.
Straight answers
Questions Cat Parents ask
What if it does not work for my cat?
Then it is on us. Try CalmGuard for 60 days from delivery. If your home is not calmer, email us any time from day 30 to day 60 and we will make it right under the 60 Day Calm Home Guarantee.
Before you decide it has not worked, check your coverage. One diffuser calms up to 700 sq ft and only the space it is plugged into, so most homes that see nothing are running one where they needed two. Email us your square footage and the rooms your cat actually uses and we will tell you what to run. That is the fix far more often than the pheromone is the problem.
How long does a CalmGuard refill last?
Each refill is 48 ml and lasts 30 days of continuous use. The kit contains three refills in total, not three plus one already fitted in the diffuser. One goes in on day one and the other two are months two and three, which is 144 ml and 90 days altogether. Write the date on the vial when you screw it in, because we would rather you checked the number than took it on trust.
How long before I see a difference?
Allow 24 to 48 hours for the diffuser to reach a steady level in the room. That window is how long the room takes, not a promise about your cat. From there, look for changes over the first 7 to 14 days, and give it the first full 30 day refill before you judge it. How quickly a given cat settles varies with the cat and with how long the stress has been running. That window applies to tension, hiding, scratching and night calling. Leave the diffuser running continuously rather than switching it on and off, and the kit carries three refills so the room holds for a full 90 days while your cat settles.
Will it help with spraying and peeing outside the litter box?
Yes, when the reason is stress, and with cats it usually is. Spraying and going outside the box are how a cat says the room stopped feeling certain. CalmGuard answers that in the room itself. It puts out a synthetic copy of the friendly signal a cat leaves when it rubs a doorway, so the space reads as claimed and familiar again and there is less reason to keep restating the border.
Get the litter setup right at the same time, one box per cat plus one, unscented litter, separate quiet rooms, away from the food and water. Then plug the diffuser into the room the boxes live in so the room your cat is being asked to trust starts reading as familiar again. CalmGuard soothes the stress behind that behavior. It is not a medicine and it does not treat any condition.
How many diffusers do I need for a multi cat house, and where do they go?
Start with coverage. One diffuser covers up to 700 sq ft, and it only calms the space it is plugged into. Count the rooms and floors your cat actually spends time in and use one diffuser for each, up to three. Two is where most homes land. A single open-plan space bigger than about 700 sq ft counts as two. Coverage is the variable almost nobody tells Cat Parents to control, and it is the most common reason a pheromone gets blamed for not working.
Then fix the room at the same time, because a diffuser is one part of the plan. Litter boxes one per cat plus one, in separate rooms, never beside the food and water. Separate feeding stations so no cat has to queue past another one to eat. Vertical space, and a second way out of every corridor and doorway, so a cat can leave rather than be cornered. Put one diffuser at the chokepoint where the standoffs happen and give that spot a second way through, a shelf or an alternative route. The layout takes away the reason to guard, the pheromone takes the charge out of the spot. If the tension is not easing after the first two weeks, it is almost always coverage. Add a diffuser at the second chokepoint rather than waiting the first one out, and the 60 Day Calm Home Guarantee covers you while you find the right number.
What is actually in it?
Synthetic feline calming pheromone at 2 percent, in a fragrance free carrier base. Drug free, non sedating, no essential oils and odorless to people. It is independently lab tested to FCC Part 15 Class B, and CA Prop 65 passed with lead and cadmium not detected.
Will it sedate my cat or change their personality?
No. CalmGuard is drug free and non sedating. It does not make a cat groggy or dull. Your cat stays entirely themselves, in a room that feels safer.
Can I smell it, and is it safe around the whole household?
People cannot smell it. There is no fragrance and there are no essential oils, so nothing is added to the air to scent the room, and Cat Parents notice the cat rather than the plug in. It is designed for indoor use around the household. Always leave the door open so your cat can move away from it, and never use it in a closed room, a crate or a carrier. Stop use if you notice coughing or wheezing. If you keep birds, plug it into a room your birds are not kept in, as you would with any plug in device. The standing safety note for CalmGuard is printed in the veterinary panel above.
What is the collar for, and how should it fit?
The collar is the away half of the kit. A cat who is anxious in the living room is usually anxious in the carrier too, and a plug in cannot follow them there. Use it for the carrier, the car, the vet waiting room and moving day rather than continuously.
It is a breakaway collar and there is no buckle to unclip. The band itself parts under a little tension, so if it catches on a branch, a fence, a chair leg or your cat's own back foot, it releases and your cat walks away. That release is the whole reason a cat can safely wear a collar at all. It is water resistant and it adjusts to fit. Two fingers should slide under it comfortably. Check the fit after the first hour, then weekly, and take it off if your cat grooms at it or the skin underneath looks red.
How much power does it use, and is it safe to leave running?
It runs on 120V and uses 4 to 5 watts, which is about the same as a night light. It is designed to run continuously and is for indoor use only. Plug it straight into a wall outlet, never an extension lead or a multi way adapter, and keep it upright and uncovered, away from curtains and bedding. It is independently lab tested to FCC Part 15 Class B, which means it will not interfere with your WiFi, TV or smart home devices.
Is CalmGuard safe for kittens?
The diffuser is for indoor household use with the door left open so any cat, including a kitten, can move away from it. Kittens grow fast, so if you use the collar, check the fit every week and let it out as they grow. Two fingers should always slide under it comfortably, and take it off if they groom at it or the skin underneath looks red. The standing safety note in the veterinary panel above applies to kittens as much as to adult cats. A kitten who learns the house as a calm place tends to stay that way, which is the reason to get the room right early rather than wait for a habit to set in.
Can I use it around a pregnant or nursing cat?
We have no safety data in pregnant or nursing cats, so we will not tell you it is fine. We would rather say plainly that we do not know. The standing safety note for CalmGuard sits in the veterinary panel above and covers this exactly.
My cat is over 11 and this behavior is new. Should I still try it?
Yes, and older cats are the ones Cat Parents come back to tell us about. Cats get less tolerant of change as they age, not more, and a house that felt fine at four can start reading as unpredictable at fourteen. Familiarity is the first thing an older cat loses, and it is exactly what CalmGuard puts back into the room.
Give them every anchor you can while the pheromone builds. Keep the bed, the bowls and the litter boxes exactly where they have always been, keep the routine boringly the same, and plug the diffuser into the room they sleep in so the space itself reads as familiar through the night. CalmGuard is drug free and non sedating, so an older cat stays entirely themselves. The standing safety note in the veterinary panel above applies.
