No. Cows only live in areas that have been opened up to allow for grazing, not within the forests themselves.

Not necessarily. It means cattle in a collective term, not cows as in only cows with calves, or dry cows or pregnant cows or bulls or steers or heifers or whatever. When a cattleman says that he has 50 head of cattle, he means cows, bulls, steers, heifers and calves, not just the cows themselves.

Bulls eat the same things that Cows and Cattle do because they themselves are cattle. See the related question below.
