Are hydrangeas poisonous to cats

Yes, hydrangeas are considered toxic to cats. The plant contains compounds called cyanogenic glycosides, which can lead to symptoms such as vomiting, diarrhea, and lethargy if ingested. While ingestion may not always be fatal, it's best to keep hydrangeas out of reach of cats to prevent any potential health issues. If you suspect your cat has eaten hydrangeas, consult a veterinarian for advice.
