To date, federal agencies like the National Institutes of Health have shown no interest in exclusively funding these studies on alcohol.

Cats drink at a significantly slower pace than ruminants, who face greater natural predation hazards. Ruminants and most other herbivores partially submerge the tip of the mouth in order to draw in water by means of a plunging action with the tongue held straight.

Cirrhosis, on the other hand, is irreversible and can lead to liver failure and liver cancer, even if you abstain from alcohol. With continued alcohol use, steatotic liver disease can lead to liver fibrosis. When your liver finishes that process, alcohol gets turned into water and carbon dioxide.
Current research points to health risks even at low amounts of alcohol consumption, regardless of beverage type. The term “drinking” is often used metonymically for the consumption of alcoholic beverages. Evidence-based hydration experts say that the amount of drinking water needed depends on ambient temperature, activity level, body size, and sweat rate. Lack of hydration causes thirst, a desire to drink which is regulated by the hypothalamus in response to subtle changes in the body’s electrolyte levels and blood volume.
