The Black Nightshade, scientifically known as Solanum nigrum, is a toxic plant for cats. This annual herb contains solanine, a poisonous glycoalkaloid compound that can cause severe adverse effects when ingested. Black Nightshade is commonly found throughout North America, Europe, Asia, and parts of Africa, often growing in disturbed areas such as fields, gardens, and roadsides.

Symptoms your cat may have

If a cat ingests any part of the Black Nightshade plant, especially the unripe green berries or leaves, it may experience severe symptoms due to the toxic solanine. These symptoms can include hypersalivation (excessive drooling), inappetence (loss of appetite), severe gastrointestinal upset (vomiting and diarrhea), drowsiness, confusion, behavioral changes, weakness, dilated pupils, and a slow heart rate. In severe cases, respiratory distress and death can occur.

Potential diagnosis your Vet may give

If you suspect your cat has ingested the Black Nightshade plant, it is crucial to seek immediate veterinary care. Your veterinarian will likely perform the following steps to diagnose and treat the potential poisoning:

  1. Conduct a physical examination to assess the cat’s condition and vital signs.
  2. Obtain a detailed history of the incident, including the plant part ingested and the approximate quantity.
  3. Perform blood tests to check for abnormalities or signs of toxicity.
  4. Induce vomiting or administer activated charcoal to remove any remaining plant material from the digestive system.
  5. Provide supportive care, such as intravenous fluids, oxygen therapy, and medications to stabilize the cat’s condition.
