Fortunately, while it isn't impossible, experts note that it is unlikely cats will experience severe symptoms from hydrangea poisoning.'Thankfully this severity of hydrangea poisoning is rare,' says Dr. Tony Coronado, veterinarian and Vice President of Emergency Medicine for Thrive Pet Healthcare.Nevertheless, it is always best to seek professional veterinary advice if you suspect your pet has ingested something they shouldn't have.'You should always contact a veterinarian, Pet Poison Helpline at 855-764-7661 or the ASPCison Control at 888-426-4435 as soon as possible,' Dr. Coronado says. 'Do not wait until you see signs of toxicity. Successful management of any toxin ingestion is rooted in early care and decontamination,' Dr. Coronado adds.
