Anyone who has ever owned a cat knows that not only do cats love meat, they also have a fondness for plants like “cat grass”. The so-called “cat grass”, that is, the pet can eat grass plants. However, people will inevitably have questions. Compared to cat food, these grass plants are not tasty. Why is it still so attractive to the cat?

What’s even stranger is that they spit it out again after eating it, and people are baffled by this. Benjamin Leslie Hart of the University of California, Davis School of Veterinary Medicine, and his team pointed out that the behavior of eating grass is not to induce vomiting when sick. And is not an acquired behavior but a response of the animal, and that not all cats will vomit after eating grass.

What is Cat Grass?

It is tiny wheat seedlings, barley seedlings, oat seedlings, dogwood, or the ordinary grass on the lawn outside, basically said to be grass plants. Grass plants with narrow, long leaves and pointed leaf tails, the color is clear and bright, light green to dark green are available.

A Common Phenomenon

The study collected observation data from more than 1000 cat addicts(who observed and cared for cats for more than three hours a day). The data concluded that only 11% of cats never showed herbivorous behavior, which means that 89% of cats have the habit of eating grass.

Of this 89%, 61% of cats ate grass more than ten times significantly, and more than 50% of cats had a daily or weekly pattern of herbivory. More than 50% of the cats have a daily or weekly eating pattern. In addition, 91% of the cat addicts said that their cats would eat grass when they were healthy, and only 27% of them said that their cats vomited after eating grass.

Therefore, based on the above data, we can conclude that cats do not eat grass when they feel well, and vomiting after eating grass is only an isolated case.
