Jade plants (Crassula ovata) are toxic to cats. All parts of the plant—including leaves, stems, and roots—can cause poisoning symptoms when ingested. Common symptoms in cats include vomiting, loss of appetite, lethargy, uncoordinated movement, excessive drooling, and in severe cases, neurological signs or slow heart rate. Symptoms typically appear within 1-4 hours of ingestion. Veterinary care may be needed depending on the symptoms and amount ingested. It is recommended to keep jade plants out of reach of cats or choose pet-safe alternatives like Echeveria or Haworthia.
