Why camphor is dangerous for pets
Camphor is rapidly absorbed through the gut and metabolised by the liver, where it overstimulates the central nervous system and can trigger seizures.
It is commonly found in Vicks VapoRub, chest rubs, cabinet moth balls, and some topical analgesic balms — any open jar left on a counter or floor is an invitation.
Even a thin film of residue on the pet fur after contact can be licked off and absorbed, prolonging exposure long after the initial incident.
Symptoms can escalate from mild vomiting to full seizures within 1 to 2 hours, especially in small cats and toy breed dogs.
The strong medicinal odour on the breath or fur is often the first clue that camphor was accessed and consumed.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Symptoms of camphor poisoning
- Vomiting starting within 30 minutes to 2 hours of ingestion.
- Muscle tremors or twitching that begin within the first hour.
- Seizure activity in moderate to severe cases, often within 2 hours.
- Lethargy that alternates with restlessness and pacing behavior.
- A strong medicinal or camphor odour detectable on the breath or fur.
- Dilated pupils and disoriented behaviour that makes the pet walk into walls or furniture.
What to do right now
- Call your vet or the ASPCA Animal Poison Control Center at 888-426-4435 immediately — camphor poisoning can escalate within hours.
- Bring the product container so the vet can see the exact camphor concentration and any other active ingredients.
- Wipe any visible residue off the pet fur with a damp cloth — licking residual camphor from the coat prolongs internal exposure.
- Do not induce vomiting — camphor is a petroleum-derived compound and inhaling vomit can cause serious aspiration pneumonia.
- Watch closely for tremors or seizures over the next 2 hours and be ready to transport the pet to the clinic without delay if they appear.
