Cows milk is not good for cats anyway. Cats don't have lactase and get diarrhea from too much cows milk.
And raw milk is a whole other can of worms and not all that smart.
Perhaps it's according to the current understanding or it may be breed-dependent, like in humans. For instance, there is few milk production in China, because of low demand. Most Chinese are biologically unable to digest milk so the production is very limited and there were many cases of fraud and scam with a sub-standard milk products. In my experience, all local milk-based products I'd tried were not tasty, to say the least, even in Taiwan. On the other hand, when I was a kid, we used to rent a room in a country for summer and relocate to there for the entire season. The first thing my mother was doing is to find a cow owner and subscribe for daily milking her kid. So every evening, when the cows came home, I'd to take the bicycle and drive to the cow owner to drink about a liter of fresh warm milk, right from the cow. Very delicious. It was not an option for me to refuse, because it's pre-paid. Yes, a raw milk can be a can of worms, as we know today, but back at that time everything was taken more simply and perhaps the over-industrialization takes its toll. Who knows how long it will last.
Meanwhile, my cat who's 11 years old, don't like milk but he enjoys some sort of soft curd for toddlers. Consumes about four teaspoons of that substance daily for dessert.
