Are Candles Safe Around Cats and Dogs? What I Tell Pet Owners

The short answer

Candles are not automatically unsafe around cats and dogs, but the flame, the wax and the fragrance are three separate risks, and a nicer candle only solves one. The safest thing I make for a pet household is a bowl candle melted on a warmer, with no flame at all.

At nearly every market somebody picks up a bowl candle, smells it, then asks the same question with a slightly worried face: is this safe, I have a cat. After price, it is the question I get most.

The honest answer is longer than yes or no. Most of what is written about candles and pets is either reassurance from people selling candles, or a flat no from people selling nothing.

So: what the ASPCA, the Ontario SPCA and vet-reviewed sources actually say, which scents land on the caution lists — some of them mine — and the one change that removes the biggest risk.

The flame is the risk you can delete today. A tail knocks over a lit candle. It cannot knock over one that was never lit.

A shallow bowl of hand-poured wax topped with dried flowers and tied with jute twine, sitting unlit — This one is made to be melted on a warmer. Almost nobody lights it, and that is the point.

What candle scents are toxic to cats and dogs?

VCA Hospitals lists these essential oils as poisonous to cats: oil of cinnamon, citrus, pennyroyal, peppermint, pine, sweet birch, tea tree, wintergreen and ylang ylang. Both ingestion and skin contact can be toxic.

Why cats. VCA says they are particularly sensitive because they have a lower number of certain liver enzymes needed to metabolise these oils. The Ontario SPCA, citing the ASPCA, says the same.

The distinction nobody draws. Those lists are about essential oils, usually concentrated or diffused. A candle carries fragrance oil at a far lower concentration, and I have found no reputable source that has tested burning candles the same way.

What I do with that. The families on those lists that overlap my own shelf are eucalyptus, citrus, pine and cinnamon. For a cautious cat household that rules out my Eucalyptus Mint, Lemon Verbena, Bergamot and Thyme and Cinnamon Apple Berry, and the Eucalyptus and Lemon Pearl Wax. Vanilla, lavender, sandalwood and coconut are not on those lists.

Are soy candles safe for pets?

Soy is better, and still not a safety claim. GoodRx, reviewed by Ghanasyam Bey, DVM, recommends unscented candles of soy, beeswax or vegetable wax, as less likely to contain harmful chemicals.

Read that word again: unscented. A soy candle with a heavy fragrance load is still a scented candle. My 9 oz keepsake is 8 oz of soy wax to a full ounce of fragrance — a lot of scent, and I would rather say so than let the word soy do work it cannot.

What should I do if my dog eats candle wax?

Ring your vet, not the internet. The ASPCA Animal Poison Control Center is on (888) 426-4435. I make candles, not diagnoses, and I will not tell you to wait and see.

What the risk is. The same GoodRx piece says a piece of candle can lodge in the gastrointestinal tract and cause an upset stomach, or a blockage that may need surgery. It also notes that batteries in flameless candles can cause internal burns if swallowed — worth knowing if you reached for one as the safe option.

How do you burn a candle safely around a curious cat?

Height is not a plan. A cat who gets on the counter gets on the mantel.
Ventilate, door open. The ASPCA notes pets can be overwhelmed by scents that seem mild to us, and that pets with breathing problems may be better off without. The Ontario SPCA advises against diffusing where an animal is confined to a small space.
Never unattended, not for the length of a shower.
Know the signs. VCA lists drooling, unsteady walking, trouble breathing, vomiting, lethargy, tremors and pawing at the mouth or face. That is a phone call, not a wait.

Birds are a different answer. The ASPCA is unambiguous that birds should not be exposed to diffused oils, as their respiratory tracts are very sensitive. With a bird in the house I would not melt anything scented.

Is a candle warmer actually safer for pets?

The number that matters My 15 oz bowl candle gives about 300 hours on a warmer against about 90 lit — and on the warmer there is no flame, no smoke and no soot.

It removes the flame, not everything. A warmer is still a hot plate on a cord, and a cord at floor level is its own problem with a kitten about. Put it where nothing dangles.

And it does not answer the fragrance question: if your cat is asthmatic, the answer is less scent.

What to change tonight

Lift the botanicals off and shut them in a drawer. Everything on top of my bowl candles comes away: twine, flowers, dried orange, cinnamon, tag.
Move it off every surface a tail passes at speed.
Pick one room and leave the door open so the animal can leave.
Check your scent against the list above; vanilla, lavender or sandalwood is the cautious pick.
Save (888) 426-4435 in your phone as ASPCA Poison Control.

From my kitchen table

I used to answer this one with "mine are soy", because that is what everyone in this trade answers. I stopped: it is a wax type pretending to be a safety claim, and it is not what anyone was asking.

Now I ask what the animal is like. A cat who sleeps through everything and a beagle who eats what he finds do not need the same candle out of me. Tell me which you have and I will tell you which of mine I would not send.

The short version

You do not have to give up candles because you have a cat or a dog. Take the three risks in order: the flame you can remove tonight, the wax your vet's number is for, and the fragrance nobody has properly tested.

Soy is not a safety claim. A warmer is not a cure. But of a lit candle on a side table and the same wax melting quietly on a plate, only one can be knocked over.
