FYI, according to Oxford's Advanced Learner's Dictionary (6th Edition):
pet/noun=an animal that you have at home for pleasure, rather than one that is kept for food or work
...in summary, a normal,sane human being will not harm (in any way) anything or anyone that they love. For example, if you're NOT crazy, you won't kill your, say, sister...or purposely cut off your sweetheart's finger. I know of people who have chickens as pets and they DON'T eat chicken at all. And i also have met people who have goldfish as pets but DO eat BBQed pomphret and seabass (as long as not goldfish)...
So the moral of the story is...?
