The Morning Glory (Ipomoea spp.) is a beautiful flowering plant that can pose a significant toxic threat to cats if ingested. While cats are not specifically allergic to morning glories, these plants contain toxic compounds that can cause various health issues in felines.

The danger lies in the plant’s indole alkaloids, including lysergic acid, lysergamide, elymoclavine, and chanoclavine. Morning glories are commonly found in gardens, on trellises, and as ornamental vines in many households, making them easily accessible to curious cats.

Assessing the Toxicity Level of the Morning Glory Plant

(Level 4) - Highly Toxic

Should you suspect poisoning, visit your vet at once or contact the APCC 24-Hour Emergency Poison Hotline.

  • 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.

Health symptoms your cat might show

If a cat ingests any part of the Morning Glory plant, it may experience a range of symptoms due to the toxic compounds present. The severity of these symptoms can vary depending on the amount consumed and the individual cat’s sensitivity. Cat owners should be vigilant and watch for the following signs of Morning Glory poisoning:

  • Gastrointestinal distress, including vomiting and diarrhea
  • Lethargy and weakness
  • Loss of appetite
  • Dilated pupils
  • Disorientation or confusion
  • Tremors or seizures
  • Hallucinations (in severe cases, particularly if seeds are consumed)

In some cases, cats may also experience neurological symptoms due to the psychoactive properties of certain compounds found in Morning Glory plants, especially in the seeds.
