Questions about Japanese Andromeda
Is Japanese Andromeda toxic to cats?
Yes, Japanese Andromeda (Pieris japonica) is highly toxic to cats. It contains grayanotoxins, and ingestion of any part of the plant can be serious — even a small amount warrants immediate veterinary attention.
What symptoms will my cat show after eating Japanese Andromeda?
Early signs include excessive drooling, vomiting, diarrhea, and abdominal pain. As toxicity progresses, watch for weakness, depression, low blood pressure, and slow or irregular heart rate. Severe ingestions can lead to cardiovascular collapse, coma, and death.

All parts of the plant are considered toxic. The grayanotoxins responsible for poisoning are present throughout Pieris japonica, so there is no safe portion for a cat to ingest.

Yes, Japanese Andromeda is highly toxic to dogs. It contains grayanotoxins, which disrupt nerve and muscle function, and any ingestion should be treated as a medical emergency.
What symptoms will a dog show after eating Japanese Andromeda?
Early signs include excessive drooling (often triggered by the plant's turpentine-like taste), vomiting, abdominal pain, and diarrhea. These typically appear within 6–8 hours of ingestion. More serious cardiovascular signs — slow or irregular heart rate, low blood pressure, weakness, and prostration — can follow, and large ingestions can be fatal within 1–2 days.

Call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately — do not wait for symptoms to appear. Any suspected ingestion is a medical emergency.

Which part of Japanese Andromeda is poisonous to dogs?
Grayanotoxins are present throughout the plant, so all parts — leaves, flowers, and stems — are considered toxic. The leaves have a turpentine-like taste that often triggers immediate excessive salivation when chewed, which can be an early warning sign of ingestion.
