Safety status
What this means for your cat
Cats should be kept well away from Japanese andromeda — ASPCA notes that ingestion of even a few leaves can cause serious problems. The plant contains grayanotoxins that disrupt sodium channels in nerve and muscle cells, and the most dangerous effects are cardiovascular: collapse, low blood pressure, and slow or irregular heart rate.
What to watch for
Hypersalivation, vomiting, and diarrhea are typical early gastrointestinal signs. Watch closely for cardiovascular signs: weakness, depression, low blood pressure, slow or irregular heart rate, and cardiovascular collapse. Severe ingestions can progress to coma and death.
Time window
Exact onset and duration are not well documented for cats specifically. Severe ingestions can progress to cardiovascular collapse; aggressive supportive care at a veterinary hospital is the standard of care.
When to call the vet
Call immediately. Any suspected ingestion is a medical emergency for cats — contact your veterinarian or ASPCA Animal Poison Control at (888) 426-4435 right away. Do not wait for symptoms to appear.
