Wisteria, a beautiful flowering vine commonly found in gardens and landscaping, is unfortunately highly toxic to cats. All parts of the wisteria plant contain harmful compounds called lectin and wisterin glycoside, which can cause severe symptoms if ingested by felines.

Cat owners should be aware of the potential dangers posed by this popular ornamental plant.

The Wisteria Plant and Its Toxicity Level

(Level 4-5) - Highly to Extremely Toxic

If you think your cat has been poisoned, don’t hesitate to visit your vet or call the APCC 24-Hour Emergency Poison Hotline for advice.

  • Level 1 - Minimally Toxic

    Ingestion may cause mild gastrointestinal upset, but is generally not life-threatening.

  • Level 2 - Mildly Toxic

    Ingestion can result in mild symptoms like vomiting, diarrhea, or drooling. Rarely fatal but may require veterinary care.

  • Level 3 - Moderately Toxic

    Eating these plants can lead to more pronounced symptoms like abdominal pain, lethargy, or difficulty breathing. Veterinary intervention may be necessary.

  • Level 4 - Highly Toxic

    Ingesting even small amounts can cause severe symptoms like organ damage, seizures, or cardiac failure without rapid treatment.

  • Level 5 - Extremely Toxic

    All parts of these plants are extremely poisonous to cats and can quickly lead to death, even with immediate veterinary care.

** Please note: Please note that toxicity level can vary based on the amount ingested and the specific cat. It's always best to keep these plants completely inaccessible to cats and seek immediate veterinary care or call the poison hotline if you suspect your cat has ingested any part of a toxic plant.
