Cat grass has no effect on humans. Cat grass is wheat seedlings, barley seedlings, oat seedlings and other gramineous plants. These plants are non-toxic and harmless when eaten, and are rich in fiber. Humans can safely grow them without releasing toxic smells. Cat grass is mainly used to promote gastrointestinal peristalsis in cats and help cats expel hair balls. It can neither be used as human food nor has any effect on humans. It is recommended that cat owners grow cat grass at home and feed their cats appropriately.

Notes for cat owners when planting cat grass:

1. Choose hydroponics or soil cultivation according to the actual situation at home.

2. Pay attention to placing the potted plants in a place with sufficient sunlight to prevent the seedlings from getting moldy.

3. Withered cat grass needs to be removed in time and new cat grass must be replanted to ensure that it can supply the cats at home.

4. Pay attention to the cleaning of potted plants and do a good job in preventing mosquitoes.
