The Lantana plant (Lantana camara), also known as Shrub Verbena, Yellow Sage, or Red Sage, is a popular ornamental plant commonly found in gardens and landscaping. While its vibrant, multi-colored flowers make it an attractive addition to outdoor spaces, Lantana is highly toxic to cats if ingested.

All parts of the plant, especially the unripe berries, contain a toxin called pentacyclic triterpenoids which can cause serious harm to felines.

Assessing the Toxicity Level of the Lantana Plant

(Level 4-5) - Highly to Extremely Toxic

If your cat shows any signs of poisoning, taking them to the vet quickly is crucial, or you can call the APCC 24-Hour Emergency Poison Hotline for guidance.

  • 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.

Signs of illness in your cat

If your cat has ingested any part of the Lantana plant, they may exhibit the following symptoms:

  • Vomiting
  • Diarrhea
  • Weakness and lethargy
  • Ataxia (staggering or abnormal movements)
