Cat Grass
Spray cat grass at the base of the leaves with a light mist twice daily. Morning and evening is suggested as this can help to hydrate your cat.
Keep cat grass in a sunny spot or place in a sunny spot when your cats not eating it. Window seals are perfect.
Every few days days, check the roots under the tray. If they look furry, this means they're looking for water. Sit the tray in shallow bowl of water for a minute and the roots will draw up the water needed and return to healthy delicate, fine looking roots again.
If the grass grows so tall the leaves start to flop over, trim an inch off the top with scissors, water and place on a sunny window sill.
