Be careful not to let the water rot or become dirty. Sunlight Management: Cat grass ideally grows in sunlight, but if it is exposed to too much direct sunlight, the grass may wither. Consider providing moderate shade or growing it indoors. Proper Harvesting Time: It is important to harvest cat grass after it has grown. Cat grass that has grown too much can become hard, making it difficult for cats to eat. It is best to harvest it in about 10 days. Cat grass is a nutritious food for cats and can help with digestion and prevent hairballs. Also, by eating grass, cats can trigger a natural vomiting reflex, which can reduce indigestion and stomach discomfort.
