"The problem is that it's nearly impossible to milk pigs. When sows are lactating, they get very aggressive. They're not docile like cows. They're smart, skittish, suspicious, and paranoid. They do not like you to get up in their business."
Lee managed to accumulate a few jars' worth of pigs' milk, from which he made half a cup of pig ricotta that he says was delicious. Getting even such a small amount of milk required jackal-like derring-do: Lee crept up on the sows while they were sleeping, frantically pinched at their tiny nipples, then ran away when they woke up and started to freak out.
Why don't we drink other animals' milk?
