The effects and functions of cats eating dogtail grass are:

1. Promote digestion. Dogtail grass can be used as cat grass to promote intestinal peristalsis in cats.

2. Help cats stimulate their gastrointestinal tract to vomit out some stomach contents, such as hair and other foreign bodies.

3. Cats often suffer from vomiting and anorexia after developing hairball syndrome. Taking foxtail grass can slow down the symptoms of vomiting in cats.

4. Excessive accumulation of cat hair in the cat’s stomach will cause abnormal digestion and absorption. At this time, you need to eat some dogtail grass to help excrete the cat hair.

5. Setariae contains a large amount of plant fiber. When a cat’s digestive system is dysfunctional, eating some setaria appropriately can help the cat digest meat protein in the stomach.
