About Dumb Cane
Dumb cane is one of the most common houseplants in Brazil and also one of the most dangerous for dog or cat owners. Its sap contains microscopic needle-shaped calcium oxalate crystals (raphides) that, when bitten into, penetrate the tissues of the mouth and release irritating enzymes. The result is usually intense, almost immediate pain and swelling, which tends to stop the animal from continuing to chew — but in cases of more extensive swelling, the airway can become compromised, requiring urgent veterinary attention.
Symptoms of poisoning
- Immediate pain and burning in the mouth
- Swelling of the tongue, lips, and mouth
- Excessive drooling
- Difficulty swallowing
- Vomiting
- In rare cases, difficulty breathing due to throat swelling
