Cats vomiting yellow water after eating freeze-dried food may be caused by gastrointestinal irritation. Feeding needs to be stopped immediately. It is best to fast for half a day and observe the cat's condition. If the vomiting is severe, it needs to be sent to the hospital for examination and treatment. If you have never eaten freeze-dried food before, do not feed too much for the first few times. Feed small amounts multiple times to let the cat accept it slowly. At the same time, pay attention to whether the date of freeze-drying is fresh. You can usually feed a little probiotics to regulate the gastrointestinal tract. If the cat's gastrointestinal tract is relatively fragile, try to feed as few snacks as possible.
