The castor bean plant (Ricinus communis), also known as the castor oil plant, is an extremely toxic plant to cats. While it is not an allergen, all parts of this plant contain ricin, a highly poisonous substance that can be lethal to felines even in small amounts

Castor bean plants are commonly grown as ornamental plants in gardens and can also be found in the wild in tropical and subtropical regions around the world.

Symptoms your cat may have

If a cat ingests any part of a castor bean plant, it can experience a range of severe symptoms due to ricin poisoning. These may include:

  • Oral irritation and burning of the mouth and throat
  • Excessive drooling
  • Vomiting
  • Diarrhea (sometimes bloody)
  • Abdominal pain
  • Weakness
  • Tremors
  • Seizures

Potential diagnosis your Vet may give

If you suspect your cat has eaten any part of a castor bean plant, seek immediate veterinary care. Your vet will likely:

  1. Perform a physical exam and ask about any potential exposure to toxic plants
  2. Run blood tests to check organ function
  3. Provide supportive care such as IV fluids, anti-seizure medication, and gastrointestinal protectants
  4. Monitor closely for signs of ricin toxicosis

Unfortunately, there is no antidote for ricin poisoning. Treatment focuses on decontamination and managing symptoms. The prognosis depends on the amount ingested and how quickly treatment is initiated.
