It is useless to soak cat grass in water for cats to drink. Cat grass helps cats vomit out hair balls by stimulating intestinal peristalsis. If you just soak cat grass in water, the nutrients in it will not be dissolved in the water, nor will it be able to stimulate the cat's intestines, nor can it induce vomiting. It is recommended that cat owners feed their cats fresh cat grass to help the cat induce vomiting.

How to feed cats grass:

1. Generally speaking, cats will take the initiative to eat cat grass after planting cat grass at home. Therefore, cat owners only need to place the cat grass within the cat's visible range when the cat needs to eat cat grass.

2. If the cat doesn’t like to eat cat grass, you can wash the cat grass, cut it into pieces, and mix it into the cat’s cat food to help the cat eat smoothly.

3. Pay attention to the fact that cat grass needs to be removed when it is moldy or withered, and new cat grass should be planted in time to ensure the supply of cat grass for cats. Do not spray pesticides on it.
