Keeping cats calm at Halloween takes a little planning, because for most felines, doorbells, costumes and surprise bangs are far more fright than fun!
Cats may be the unofficial mascots of spooky season (especially our black cat pals), but they’re also creatures of routine, so a night of knocks at the door and strangers in masks can be a lot to handle.
The good news is that a few simple steps before, during and after the big night can make a huge difference!
Why Halloween can spook your cat
Knocks, doorbells and strange faces
Your cat sees your home as their territory, so every ring of the doorbell means another stranger on their patch. A front door that keeps swinging open also gives a nervous cat the perfect chance to make a dash for it!
Costumes, masks and spooky decorations
Once your face is hidden behind a mask, your cat may not recognise you at all, and flashing lights or motion-activated spiders can be just as unsettling. Keep candles, sweets and dangly decorations well out of paws’ reach too; our guide to Halloween safety for pets has more on this.
Darker evenings and early fireworks
The clocks go back just before Halloween, so darkness falls earlier and trick-or-treating lands right when many cats would normally head out exploring. Fireworks often start popping around the same time and carry on to Bonfire Night and beyond.

Spotting a scaredy-cat: signs your cat is stressed
Cats are experts at hiding how they feel, so keep an eye out for:
- Hiding under beds or on top of wardrobes
- Crouching low, with ears flattened and tail tucked or flicking
- Wide, dilated pupils
- Puffed-up fur, an arched back or hissing
- More meowing than usual
- Going off their food or toileting outside the litter tray
- Trying to bolt through doors or windows
These are all your cat’s way of saying, “I need a bit of space right now!”
Keeping cats calm before the trick-or-treaters arrive
Bring them in before dark
If your cat likes to roam, serve dinner a little earlier to tempt them home before dusk. Then lock the cat flap, close the windows, pop out an extra litter tray and check their microchip details are up to date, just in case!
Set up a cosy safe space
Pick a quiet room away from the front door, ideally one your cat already loves, and kit it out with their bed, food, water, litter tray, a cardboard box to hide in and somewhere high to perch. An unwashed jumper that smells like you adds extra comfort.
Some cats feel happier with the run of the house and their own favourite hideouts, so follow your cat’s lead. If you do close the door, pop in regularly to check on them.
Introduce your costume early
A few days before Halloween, leave your costume or mask on the floor for a good sniff, then put it on while your cat watches. As for dressing up your cat, costumes are best left to the humans!

Tips for keeping cats calm on Halloween night
Keeping cats calm when the doorbell rings
Cutting down on knocks and rings is one of the easiest wins. Sit on the doorstep with the sweets, or leave a bowl outside with a friendly note for trick-or-treaters. If you have a video doorbell, switch the chime to silent for the evening.
Muffle the noise outside
Close the curtains and windows early, then put on soft music, the radio or the TV at a normal volume to help cover the noise outside. Stick to sounds your cat is already used to.
Stick to the usual routine
Keep mealtimes and playtime as normal as you can. Cats pick up on our moods, so stay relaxed, never scold a frightened cat, and let them come to you for cuddles on their own terms. If you’re hosting a party, ask guests to let your cat approach them first.
Helping your cat settle after Halloween
Keeping cats calm through fireworks season
Fireworks tend to carry on well past Halloween, so check the dates of local displays and keep your cat indoors on those evenings. Leaving their safe space set up for a couple of weeks gives them somewhere familiar to retreat to. Our guide on how to keep pets calm during fireworks has lots more tips!
When to call your vet
Most cats bounce back within a day or so, but call your vet if yours is still hiding or off their food once the fuss has died down. Stress can also trigger bladder problems in cats, so get in touch promptly if you notice straining in the litter tray or blood in the urine.
