thanks Trinity for the info, i will read it thoroughly tomorrow as its time for sleep but my immediate response to what exactly is a happy Cow was

"The ones I met on the farm". These cows were like love in the form of cow, i live surrounded by cows in neighbouring farms but these cows I met are like a completely different creature. It was like they glowed with the love they received from their people, i was struck by them. They seemed pretty darn happy to me and my friend. There's only three of them if I could remember. And no they don't sell the cheese to make a profit, just for home use..

those cows, plus the b12 issue have got me considering that maybe some animals actually do want to be in relationship with humans in this way. I will continue to look into it..

Im also wondering now if domesticating a pet is much different, where it is not able to self actualise because we have interfered, sterilising them, removing them from their natural environments and then holding them in captivity etc... At least a cow has a new role and isn't just left dependent and in limbo, like many pets are.

Will mull it over tomorrow :)
