Common questions
Why does my cat vomit after eating cat grass?
Long blades tickle the throat and stomach, and cats lack the enzymes to digest grass. The vomit is mechanical and harmless — it is why cats seek grass in the first place.
Is cat grass the same as catnip?
No. Cat grass is a cereal grass eaten for fiber; catnip is a mint that causes a euphoric roll-around reaction. Both are safe.
Can I grow cat grass from lawn seed?
Use untreated seed meant for sprouting or pets — lawn seed is often coated with fungicides and fertilizers that are not safe to ingest.
