Cats should not drink pure milk. Pure milk contains lactose, and most cats are lactose intolerant. Drinking pure milk will cause gastrointestinal discomfort symptoms such as diarrhea, vomiting, etc. Therefore, cats should not drink pure milk.

If your cat vomits or has diarrhea after drinking milk, please pay attention to the following:
1. Fasting and abstaining from water are necessary to prevent food from irritating the gastrointestinal tract and worsening the condition.
2. Give your cat an appropriate amount of probiotics to regulate the balance of gut flora.
3. If the symptoms improve, you can feed the pet nutritious and easily digestible food. If the symptoms do not improve, you need to take the pet to a veterinary hospital for treatment.
