Why Pets Chew Plants — and What You Can Do


🐶🐱Pets often chew on plants out of curiosity, boredom, or digestive instinct. To minimize risk:

  • Keep toxic plants out of reach or avoid them entirely.
  • Provide pet-safe grass or chew toys.
  • Use natural deterrents like citrus peels around plant pots.
