Cats’ intestines and stomachs are too sensitive and fragile, and they cannot drink more things than you think. Cats cannot drink milk, alcoholic beverages, coffee, or tap water, so you must pay attention during daily feeding.

Cats cannot drink milk. Cats lack an enzyme that breaks down and digests milk, so cats generally suffer from lactose intolerance. They are unable to absorb and break down the enzymes in milk, which can cause diarrhea, gas, and other phenomena. Long-term drinking of milk can cause gastrointestinal and kidney diseases in cats.

Cats cannot drink beer, wine, or food containing alcohol, as alcohol will be absorbed in the blood. Alcohol has the same effects on cats' livers and brains as it does on humans. If you consume more than the allowed amount of alcohol, it can damage cells in your cat's brain and body, causing vomiting, difficulty breathing, and neurological abnormalities. In severe cases, cats may fall into coma or even die.

Cats cannot drink drinks containing caffeine. Caffeine is a central nervous system stimulant. Cats that accidentally eat it can cause diarrhea, vomiting, polyuria and other problems. Excessive intake can cause cats to be poisoned, with digestive tract, neurological and cardiac symptoms, and severe cases can lead to death.

Many people choose to give their cats tap water directly for convenience, thinking that drinking tap water will be fine. People will get sick if they drink tap water for a long time, let alone cats. There are many bacteria in tap water, and the water quality in some areas is poor. Feeding it to cats will inevitably cause diarrhea. So don’t give your cat tap water for a long time, as this is not good for your cat’s health.
