Cats should not drink milk tea. Milk will cause diarrhea in cats, while tea will make cats hyperactive, which is especially bad for the kidneys. Milk tea has a high sugar content, which can affect a cat’s health after drinking it, ranging from gastrointestinal discomfort to severe diarrhea. At the same time, milk tea contains a lot of additives, which are very bad for the kidneys.

Some milk teas also contain chocolate. The theobromine and caffeine contained in chocolate are fatal to cats and may cause heart disease in cats, or even directly lead to kidney failure in cats and even be life-threatening.
