Let's start with a fact you may not want to face: during the Halloween weeks, pet poison hotlines are 12% busier than usual. Chocolate-related calls about dogs alone spike 209% compared to normal.

This isn't alarmism. By the time you hang the skeleton on the wall and pour the candy into the bowl, the “Halloween” in your cat's or dog's eyes is completely different from what you see.

First, figure out which decorations are the “look harmless but are actually deadly” kind

Pets don't distinguish between “decorations” and “toys.” In their world, things hung on the wall and things thrown on the floor are essentially the same thing — something to chew.

Fake Cobwebs
This is one of the most dangerous types of Halloween decorations, hands down. RSPCA vets repeatedly warn that fake cobwebs are extremely attractive to cats because they look like string, rope, or yarn — three things cats can't resist. Once swallowed, they don't digest, tangle into a mass in the intestines, cause intestinal blockage, and in severe cases require emergency surgery.

There's another overlooked one: when fake cobwebs are hung outdoors and blown away by the wind, they entangle birds, bats, and small mammals. A wildlife expert from RSPCA SA once said she found a nest of baby birds entangled in fake cobwebs, all dead.

Electrical decorations (wires for string lights, projection lights, and inflatable decorations)
Pets chewing wires isn't an “if” but a “when.” A chewed wire can cause oral burns in mild cases and electrocution in severe ones. A dog with a wet nose sniffing a wire and a cat crawling around the hallway are both high-risk.

Small parts and brittle decorations
Plastic eyeballs, small skeleton heads, fake teeth, glow bracelets, small bat charms — these are sized right between “chewable” and “swallowable.” Once swallowed, they either get stuck in the throat and cause choking, or get stuck in the intestines and cause blockage. In RSPCA's own words: “Some decorations cause internal damage when swallowed and require surgery to remove.”

Pumpkins
Pumpkins themselves are not toxic to cats and dogs. But that's not the problem. The problem is the amount. If a dog gnaws off half of that carved pumpkin by the door, the result isn't “ate a little pumpkin” — it's vomiting and diarrhea. Also, a carved pumpkin left outside for more than two days starts developing bacteria on its surface, and eating it leads to gastroenteritis.

Real candles and jack-o'-lanterns
A cat's tail sweeps past, a dog's tail wags, and the candle topples over. Burning fur is the mild outcome; burning the house is the severe one. The Chicago Veterinary Medical Association's advice is direct: use battery-operated candles instead of real candles.

The data tells you: Halloween is the “emergency season” for pets

You may think “my pet is well-behaved and won't eat random things.” But the data isn't on the side of “well-behaved.”

Pet poison hotline call volume increases 12% during Halloween week, making it the busiest time of the year. Calls about dogs eating chocolate spike 209% compared to normal. Trupanion pet insurance data shows that in 2023 alone, pet owners filed more than 24,000 claims for foreign object ingestion, with Halloween decorations listed as one of the clearly identified risk sources.

What hurts even more: Halloween is the second biggest holiday for lost pets, second only to the Fourth of July. Doors keep opening, strangers keep coming in, and every year cats bolt out of fear and dogs dash out the door after people.

So how do you decorate in a way that looks good without hurting your pets?

Swap real candles for battery-operated ones
This one is non-negotiable. Battery-operated candles are now very realistic, with flicker effects, warm light, and remote control. Prices range from a few dollars to over a dozen. You give up a bit of realism, but you gain no fire risk, no burn risk, and no accidents if your pet knocks them over.

Fake spider webs: either skip them or hang them high
If you really want that web-wrapped effect, hang it at a height your pet absolutely cannot reach — ceiling, chandelier, or high light fixtures. Don't hang it on the lower half of door frames, don't drape it over shrubs, and don't wrap it around low railings. Put it away as soon as you're done, and don't leave it out overnight. Once the wind blows, it becomes a wildlife trap.

Wires: hide them or use protective covers
Wrap the wires of your Halloween light strings in cord management tubes. Pet supply stores and hardware stores sell them for a few dollars a roll. If wires must cross pet activity areas, tape them to the floor or along the baseboard, and never leave them dangling — a dangling wire is a cat teaser to a cat.

Small decorations: put them where cats can't jump and dogs can't reach
Mantel, top bookshelf, top of the refrigerator. The test is simple: crouch down to your pet's height and see what it can reach. Anything it can reach, move away.

Outdoor inflatable decorations: check the stakes and power cords
The inflatable itself isn't much of a threat to pets — it's too thick to bite through. But the stakes and rope ends used to secure it are the parts pets can easily chew. Also cover the power cord connections to keep curious dogs from licking them.

What to do if your pet has already gotten into something

If you see your pet chewing on a decoration: take it away first, then observe.

Don't stick your hand in its mouth to pry it out — if it's already swallowed, prying will only stress it out more, and it may even bite you. Take away the leftover pieces and remember how much it chewed and what it was.

If these symptoms appear, call your vet or the poison hotline immediately:

Vomiting, diarrhea
Drooling, pawing at the mouth
Lethargy, not eating
Abdominal pain (yelps when the belly is touched)
Rapid breathing

The ASPCA Animal Poison Control Center 24-hour hotline is (888) 426-4435, Pet Poison Helpline is (855) 764-7661 - save both numbers in your phone right now

Don't wait and see - early versus late intervention for intestinal blockages can mean a difference of thousands of dollars and a life

One-sentence summary

90% of harm to pets from Halloween decorations is preventable - switch to battery candles, put away fake spider webs, hide cords, hang small items high, lock candy in a cabinet - after these five things, both your pet and your Halloween can survive

Decorations are for looking good, not for driving you to the ER in the middle of the night
