If your cat is hiding more than usual, hissing at the new kitten, or turning the annual vet trip into a wrestling match, a calming spray can genuinely help — but only as part of the picture. The short version: a pheromone spray like Feliway gives many cats a sense of "this place is safe", and a supplement like Zylkene can support calmness from the inside. Neither is magic, though, and they work best alongside the simple home fixes below. First, a quick word on what's actually stressing your cat.
What stresses NZ cats
Cats are creatures of habit, and most of their stress comes from change — even change we'd think nothing of. Common triggers in Kiwi homes include:
- A new home, baby, or pet. Moving house, a new partner, a newborn, or a second cat or dog all shake up the territory your cat thought it had sorted.
- Vet and carrier trips. For a lot of cats the carrier itself is the villain — it only ever comes out before something scary happens.
- Fireworks and storms. Guy Fawkes in early November, New Year, and the odd big southerly can rattle even a confident cat.
- Multi-cat tension. Two cats sharing one space can simmer with quiet conflict, even if they never openly fight.
- Spraying and scratching. Urine-marking on walls or furniture, and frantic scratching, are often a cat trying to feel more secure in its own patch.
Stress shows up in small ways: hiding, off their food, over-grooming, going to the toilet outside the tray, or being snappier than usual. Spotting it early makes it far easier to settle (Cornell Feline Health Center).
This one really matters. If your cat suddenly starts weeing outside the litter tray, over-grooming a bald patch, hiding away, or acting unlike itself, see your vet first. Those signs can point to a medical problem — pain, a urinary issue, or illness — not just stress (Merck Veterinary Manual). A calming product may help once your vet has ruled out anything physical, but it should never be your first and only move. Toileting trouble in particular can be an emergency in male cats.
The calming toolkit: pheromone sprays and supplements
Once you've got any medical worries ruled out, this is the kit that helps most.
Feliway pheromone spray and diffuser
When a relaxed cat rubs its face on the corner of your couch, it's leaving a scent marker that says "this is safe and mine". Feliway is a man-made copy of that exact pheromone — scentless to us — and the idea is to surround your cat with that reassuring signal.
There are two formats, and they do different jobs:
- The spray is for targeted, short-term moments — most famously the cat carrier. Give the inside of the carrier 8 to 10 pumps, then wait about 15 minutes before you put your cat in, so the spray dries and only the pheromone is left. Never spray it onto your cat. You can also spritz a spot your cat keeps scratching or marking.
- The diffuser is a plug-in for the home. It quietly releases pheromone into a room around the clock, which suits longer settling-in jobs like a house move, a new baby, or ongoing multi-cat tension. Plug it into the room your cat spends the most time in, and leave it running.
If you'd like to grab one, here's where to get them in NZ:
Check price at Petstock Check price at Pet DirectZylkene — a calming supplement
Zylkene is a nutraceutical you give by mouth, made from a protein found in milk that's long been linked to the calm, settled feeling kittens get after a feed. It comes as a capsule you can open and sprinkle over food, and it's non-sedating — your cat stays its normal, alert self. Owners often reach for it ahead of a known stressful stretch, like moving house or a fireworks season, and some use it alongside a Feliway diffuser.
Check price at VetpostZylkene is widely used and generally very well tolerated, but it's still worth a quick word with your vet before you start — especially if your cat is older, unwell, or already on other medication (New Zealand Veterinary Association). They can also help you work out whether a supplement is even the right tool for what's going on.
The fixes that matter most (and cost nothing)
Here's the honest bit: pheromones and supplements help many cats, but they aren't magic, and they work far better when the basics are right. A spray can't fix a home where a stressed cat has nowhere to hide and one shared litter tray. Sort the environment first, and the products do their job properly.
- Enough litter trays. The rule of thumb is one tray per cat, plus one — so two cats means three trays — kept in separate, quiet spots. Too few trays, or trays in busy areas, is a leading cause of toileting stress (SPCA New Zealand).
- Vertical space. Cats feel safest up high. A cat tree, a cleared shelf or the top of a wardrobe lets your cat survey its world and stay out of reach of whatever's bothering it.
- Hiding spots. A cardboard box on its side, an igloo bed, or a quiet cupboard gives a worried cat somewhere to retreat. Never drag a cat out of its hiding place.
- A steady routine. Feed, play and quiet time at roughly the same times each day. Predictability is deeply reassuring to a cat.
- A slow introduction. Bringing in a new cat, dog or baby? Go slowly, swap scents before any face-to-face meeting, and keep the newcomer separated at first so nobody feels invaded.
Get these in place and you may find your cat settles without much else at all — and if you do add a spray or supplement, it'll have the best chance of working.

When to see your vet
Calming products and a good home setup will settle a lot of everyday cat stress. But please see your vet if:
- The stress is ongoing or severe, or it's getting worse rather than better.
- There's any change in toileting — going outside the tray, straining, or blood — which can be a medical emergency, especially in male cats.
- Your cat is over-grooming, hiding constantly, off its food, or behaving in a way that's suddenly unlike itself.
- You've tried the home fixes and a calming product for a few weeks with no real change.
Your vet can rule out a health problem, and for stubborn anxiety or behaviour issues they can point you to a vet behaviourist or, where it's truly needed, prescription options. Stress that won't shift is a medical conversation, not a shopping one.
The bottom line
A calming spray for cats is a genuinely useful tool — Feliway around the home or in the carrier, and a supplement like Zylkene for tougher stretches, both help a lot of cats feel safer. But they work best on top of the basics: enough litter trays, places to hide and climb, and a steady routine. And whenever your cat's behaviour changes suddenly, treat that as a reason to ring the vet, not just a reason to buy a spray. If you've got an anxious dog in the mix too, our guide to calming products for anxious dogs covers their (quite different) toolkit.
