Angel ivy (also called devil's ivy or Epipremnum pinnatum) is toxic to cats and should be kept out of their reach. The plant contains calcium oxalate crystals, which can cause oral irritation, drooling, difficulty swallowing, and vomiting if cats chew on or ingest the leaves or stems. In severe cases, ingestion may lead to difficulty breathing or swallowing. Cats are naturally curious and may nibble on houseplants, making this a genuine concern for pet owners. If you suspect your cat has eaten angel ivy, contact your veterinarian or an animal poison control center promptly. To protect your cat, place the plant in a location they cannot access, such as a high shelf, hanging basket, or closed room. Consider choosing cat-safe alternatives like spider plants, Boston ferns, or African violets if you want greenery in your home. Even non-toxic plants should be monitored, as excessive chewing on any plant can cause digestive upset. When in doubt about any houseplant's safety, consult with your veterinarian before bringing it into a home with cats.
