From my reading of Gandhi I had learned how some people in India regard eating cow as unspeakably repulsive. I realized I felt the same way about cats and dogs: I could never eat them. Were cows so different from cats and dogs that there were two moral standards, one that applies to cows, another that applies to cats and dogs? Were pigs so different? Were any of the animals I ate so different?
