Cats?
My cats like the odd drink of milk and they're old farts.
(Although I do agree that it's strange that milk is so popular given the fact that most people can't digest milk - the enzyme you need tends to disappear in adulthood).

Infant mammals nurse on their mothers to drink milk, which is rich in lactose. The intestinal villi secrete the enzyme called lactase (β-D-galactosidase) to digest it. This enzyme cleaves the lactose molecule into its two subunits, the simple sugars glucose and galactose, which can be absorbed. Since lactose occurs mostly in milk, in most mammals the production of lactase gradually decreases with maturity due to a lack of constant consumption.
Many people with ancestry in Europe, West Asia, India, and parts of East Africa maintain lactase production into adulthood. In many of these areas, milk from mammals such as cattle, goats, and sheep is used as a large source of food. Hence, it was in these regions that genes for lifelong lactase production first evolved. The genes of adult lactose tolerance have evolved independently in various ethnic groups.[6] By descent, more than 70% of western Europeans can drink milk as adults, compared with less than 30% of people from areas of Africa, eastern and south-eastern Asia and Oceania.[7] In people who are lactose intolerant, lactose is not broken down and provides food for gas-producing gut flora, which can lead to diarrhoea, bloating, flatulence, and other gastrointestinal symptoms.
