Why is My Pet Eating Grass and Plants?

     The answer for why many dogs and cats eat grass and other plants is not clear – cut. Some of the more popular theories are that they have a deficiency in diet, need for more fiber, or that it is a natural instinct inherited from ancestors to rid the body of intestinal parasites. Recent research suggests that most pets eat grass when they are not showing signs of illness. In a recent study conducted at UC Davis by Karen Sueda and her colleagues, it was reported that only 9% of dogs appear ill prior to consuming plant material and only 22% were seen vomiting afterward. It also suggested that younger animals tend to eat plants more often and less frequently appeared ill before plant – eating. Younger animals also have an increased likelihood of consuming other non- grass plants.

     If your pet is consuming plant material, it may be normal behavior. If your pet has other signs of illness, please consult your veterinarian. Your pet should have a complete physical exam to rule out any underlying illnesses.
