Cat grass is an essential item for cat-owning families. Not only is it rich in nutrients, but more importantly, it is very beneficial for preventing and treating hairballs in cats. When cats ingest a lot of hair, feeding them cat grass can help them expel hairballs. Therefore, cat grass plays a vital role in a cat's daily life. 
Cat grass can be grown at home or bought ready-made. When feeding cat grass to your cat, it's important to use scissors to cut a small bunch from the grass box, then cut it into small pieces and add it to your cat's favorite food. Some cats love yogurt, so you can add cat grass to the yogurt to make "green-topped yogurt." It's recommended to give cat grass once a day during hot weather, as cats shed more fur and ingest more hair while grooming. It's also advisable to supplement their diet with Royal Canin cat food, especially the hairball-resistant formula, to help them expel hairballs and maintain gut health. During cooler seasons, you can give your cat cat grass every two to three days. If your cat is experiencing heatiness or constipation, increasing the amount of cat grass can help alleviate these symptoms.
In addition, cat grass can also be used as a toy for cats. Owners can make cat grass into balls, hang them up with twine, and play with them. Even if the cat gets scratched, it's okay; eating it will help clean out the hairballs. Therefore, cat grass can prevent hairballs and also serve as a toy for cats. Cat owners should definitely get some on hand!
