Jasmine flowers are indeed toxic to cats. If a cat accidentally ingests certain components of jasmine, it may experience symptoms such as drooling, vomiting, and cyanosis of the conjunctiva. More seriously, prolonged exposure to jasmine can lead to poisoning symptoms, such as dilated pupils, fever, weakness, convulsions, tremors, and vomiting. Therefore, to ensure your cat's safety, keep jasmine flowers out of their reach.

If your cat has ingested jasmine flowers and is showing signs of poisoning, immediately take it to a well-ventilated area and seek medical attention. Treatment may include inducing vomiting, administering an antidote, and other emergency measures.
