Scientists have revealed that cats eat grass

do a lot of weird things, but the strangest thing to say is to eat grass - usually spitting out after a few minutes. Now, after centuries of exploration, scientists have finally found the answer.
researchers surveyed more than 1,000 cat owners online and spent at least three hours a day observing and accompanying their pets. As many cat breeders are aware, it is extremely common for cats to eat plants - 71 per cent of cats are found to eat grass at least six times in their lifetime, while only 11 per cent of animals are never observed eating plants.
online explanations for cats eating grass mostly believe that this behavior helps animals vomit when they get sick. But only about a third of herbivores were observed vomiting after eating plants, and 91 percent of respondents said their cats did not get sick before eating plants.
, the researchers say, vomiting is only an occasional by-product of grass eating, not the purpose of the animal's behavior.
they report at the annual meeting of the International Society for Applied Zoology in Bergen, Norway, that eating plants is an instinct and is good for the evolution of cats, at least before.
the researchers' theory is based on studies of chimpanzees and other wildlife that chewing plants hard helps animals excrete intestinal parasites by increasing muscle activity in the digestive tract. Of course, these parasites may no longer be found in cats today.
authors believe that this strategy may have evolved first from a distant ancestor. (Scientists haven't tested another common hypothesis: that eating grass helps cats spit out hairballs)
The team's advice to cat owners is to buy or grow some indoor grass for your pet to eat. This will give them a chance to exercise this natural behavior with safe, non-toxic plants. If your cat vomits later, at least you can be comforted by your knowledge, because you know it wasn't intentional or malicious... （
