What to do right now

  1. Call your vet or an animal poison line now, even if your cat seems fine. In the US: Pet Poison Helpline (855) 764-7661 or ASPCA Animal Poison Control (888) 426-4435, both open 24/7 (a fee applies).
  2. Don't make your cat vomit and don't give anything by mouth unless a vet tells you to.
  3. Keep the product, label or package, and note roughly how much your cat may have licked or eaten, and when.
  4. If the product is on your cat's fur, tell the vet: cats groom and swallow whatever is on their coat. Ask before bathing your cat.

Go to an emergency vet if

  • Your cat has a seizure, trembles, or acts confused or overexcited.
  • Your cat has trouble breathing, collapses, or is very drowsy.
  • Your cat swallowed a mothball or a noticeable amount of a camphor rub, balm or oil. Don't wait for signs.

Symptoms to watch for

  • local skin irritation
  • nausea
  • vomiting
  • diarrhea
  • depression
  • seizures
  • respiratory depression
  • death

How much is dangerous

No toxic dose for cats has been published. Cats may be more sensitive than dogs because their liver breaks camphor down less efficiently, so treat any exposure as urgent.

Why it's dangerous

Camphor is rapidly absorbed through the skin and gastrointestinal tract, leading to central nervous system stimulation and potential respiratory depression.

Toxic compound: Camphor

How vets treat it

There is no antidote. Vets give supportive care, such as IV fluids, anti-seizure medicines and close monitoring, as they do for other camphor and mothball poisonings.

Outlook

Death is rare. With mothball poisoning in general, most cats survive when they are treated early.

Where pets are exposed

  • Chest and muscle rubs, balms and medicated lip balms, such as Vicks VapoRub, Tiger Balm, Carmex and Campho-Phenique.
  • Camphor products put on a pet's skin. Camphor passes easily through the skin, so this alone can poison a pet.
  • Camphor mothballs and some moth repellents.
  • Essential oils and fragrance products that contain camphor.

Prevention

  • Never put camphor products on a dog or cat, whether for pain, a cough or anything else.
  • Keep rubs, balms and lip balms in a closed cupboard, not in handbags or on bedside tables. Dogs chew tubes and jars.
  • Store mothballs in sealed containers out of reach, and never leave loose mothballs around the home or garden.
  • Keep essential oils out of reach, and use diffusers only in well-ventilated rooms.

Good to know

Camphor should never be applied to dogs or cats due to risks for poisoning; it is readily absorbed across the skin.

Common questions

Is Vicks VapoRub toxic to dogs?

It can be. It contains camphor along with menthol and eucalyptus oil. Eating it can upset a dog's stomach, and chewing up the jar can block the gut, so call your vet or a pet poison line if your dog gets into it.

Can I put camphor, Tiger Balm or Vicks on my dog or cat?

No. Camphor passes easily through the skin and can poison dogs and cats. Ask your vet for a pet-safe option instead.

Should I make my pet throw up after eating camphor?

No. Don't induce vomiting or give anything by mouth unless a vet tells you to. Making a dog vomit after camphor can trigger seizures, so call your vet or a pet poison line right away instead.

Are cats more sensitive to camphor than dogs?

Possibly. A Vet Times case review says cats may be more sensitive because their liver breaks camphor down less efficiently, but no toxic dose for cats has been published. Treat any exposure in a cat as urgent.
