Why is Cigarette Tar Poisonous?

Cigarette tar contains harmful chemicals that can cause irritation and damage to the gastrointestinal tract.

It is also a potential carcinogen and can lead to serious health issues in pets if ingested.

Cats may be more susceptible to the toxic effects of cigarette tar due to their grooming habits.

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 cigarette-tar poisoning

  • Vomiting, diarrhea, and depression within 2-4 hours after ingestion.
  • Increased heart rate and difficulty breathing if ingested in large amounts.
  • Potential for long-term health issues such as lung and heart problems.

What to do right now

  1. Call your vet or a poison line immediately.
  2. Do not induce vomiting unless directed by a veterinarian. It can worsen the condition.
  3. Provide your pet with plenty of water to drink and monitor for signs of improvement or worsening.
If your pet shows any of the signs above, go to the nearest emergency vet now and call ahead.
