Not normally

goat milk
Generally only female goats produce milk. However, on very rare occasions male goats (bucks) may begin producing milk. Such bucks are generally otherwise perfectly normal. This usually only happens with pygmy goats.
Both are good and you need both to have kids or produce milk.
For the same reason sheep and cows do. It holds milk that is in turn used to feed their kids in in the case of milking goats (who produce more milk the other goat breeds) will also be used for human consumption.
Maybe it's not milk
Yes, goats produce milk, as all mammals do.
milk it's healthier too Goat milk is milk produced by a dairy goat
Once they have kidded
Male "cows" are not cows. They are bulls or steers, which do not produce milk. Female bovines that have had a calf are called cows and those cows produce milk. Young female bovines that have not had a calf are called heifers, and they are not able to produce milk because they have not had a calf yet.
No, you cannot milk a cat because cats do not produce milk like cows or goats.
Neither. Female goats produce milk after the kids are born, and for up to two years thereafter, depending on breed, lineage, and how they are managed. After they dry up, they can then be bred again, and will produce milk again after their next kidding.
