I Have A Soft Spot For Cows

When I am out in the country, I am always drawn to cows, and have studied the way they behave. When you make a noise, like call on them, they stare at you and as a heard they slowly get near each other then move closer towards you. I always feel it is a little sad when i say goodbye to the cows as I think they look a little sad, and they are all numbered, with only some time to live. So yes maybe I would want a pet cow, and would not have to go to the shop for milk. What would you call your cow ?
