I became a vegetarian after seeing a doco on animal cruelty that also had scenes of dogs and cats being killed for food. It wasn't the fact that they ate these animals that shocked me - I grew up on horse meat, same kind of thing - it was the way in which they were kept and how they tortured them to death. The same doco showed shocking images of the conditions the cattle in Europe was often kept in. So I went vego. For a couple of years. That was almost 20 years ago and I can still remember most of the worst scenes in detail.
