If you want to be a proper vegetarian and have to avoid all products like gelatine etc, are there any surprises you should be on the look out for? e.g -are there any food out there that you might eat because you think it doesn't contain animal products but really contains animal based ingredients. Also is it possible to avoid animal products in non-food based items? For example will my car or house contain any hidden nastiness that you wouldn't necesarily think about if you weren't in the know?
