What to do if your cat accidentally comes into contact with, chews, or eats hoya heart plants: Nothing alarming should occur after your cat accidentally chews on the leaves of a hoya heart plant. However, plant matter consumption always comes with risks. As an obligate carnivore, she does not have the ability to digest large amounts of plants. Accidental choking or intestinal blockage may occur if a big chunk is eaten in one sitting.
Also, do not spray chemicals or apply harmful fertilisers to your hoya heart plant as these may poison your cat. If you suspect this happened, speak with your veterinarian without delay. Take her to the emergency clinic if she manifests any symptoms of poisoning. Watch for salivation, vomiting, diarrhea, twitching and fitting, difficulty in breathing, shock, and collapse. She may also experience skin inflammation or swelling, depression or coma, and changes in her drinking, urinating, and eating.
