Common questions
Why does my dog love the cat’s grass pot?
Dogs also graze grass for fiber and taste. Sharing the pot is fine nutritionally — just keep it seeded so there is enough for both pets.
Is wheatgrass juice for humans okay to share with my dog?
A small amount of plain juice is safe. Avoid versions blended with onion, garlic, grapes or xylitol-sweetened ingredients.
