I am prompted to write this article in response to the still widespread misconception that fruit and/or vegetables in the diet are beneficial to the cat. Although the picture of a cat roaming the forest, selecting plump and fresh fruit bursting with vitamins, and browsing for healing and healthful herbs may be romantic, but far from the truth. People continuously make reference to cats in the wild eating a variety of fruit and vegetables. I am convinced that this statement is a pure creation of the imagination. How many of us have the opportunity to observe the natural behavior of wild cats? When referencing the world authority on wild cats (IUCN/SSC Cat Specialist Group – International Union for Conservation of Nature and Natural Resources/Species Survival Commission) it becomes apparent that not even enough professional biologists in the world study the small cats before many of these species will go extinct under our very eyes. The very ancestor of our beloved domestic companion, the African Wildcat (Felis silvestris lybica) - a dweller of Africa’s Sub-Sahara - is loosing its foothold through habitat loss and interbreeding with its domestic progeny.
Not all cats eat grass or plants, and they shouldn't. Outside, plants and grasses may be treated with insecticide, or contaminated with a number of other toxins, so it's best that she doesn't eat them. Many houseplants and flowers are toxic to cats, too. Most cats will eat grass when they have intestinal upset, because they know that the grass will make them throw up so they'll feel better. However, all cats don't HAVE to eat grass or show an interest in it. 'Cat grass', which you've seen sold in pet stores and in infomercials, etc., are natural 'greens' for cats who like to much on that stuff; that usually causes vomiting, too.
