Cat grass cannot be eaten every day. Cats eat cat grass mainly to stimulate their gastrointestinal tract and induce vomiting of hair balls. Because the crude fiber contained in cat grass is difficult for the gastrointestinal tract to digest, eating too much cat grass will not only easily cause diarrhea, but also have a negative impact on the gastrointestinal tract. ​​​​​​

Cats eating cat grass every day will irritate their gastrointestinal tract and cause vomiting or diarrhea. It is recommended to feed cat grass once a week. Cat grass is not recommended for cats under 4 months old.
