When a cat has a cold, you must first keep it warm to prevent the cat's cold from getting worse. If the cold is more serious, you can take some pet cold medicine and anti-inflammatory drugs appropriately; then add nutrients and water to the cat, and feed it some relatively light and easy-to-digest food. For example, chicken, beef, egg yolk, etc.; at the same time, keep the room dry and ventilated, and let the cat get more sun, which will help the cat recover as soon as possible.
