"Don't plants have feeling too?" - This question is usually asked by spiteful meat-eaters who want to "prove a point." If we have to answer it though, we'd say... We don't know, but most vegetarians will tell you that probably not. Anyway, it's all about drawing the line somewhere. And drawing it at animals (and animal products) is acceptable to most vegetarians and vegans. Need more proof? Go to a slaughterhouse and watch a pig get immersed in scalding water while still half-conscious and observe its reaction, and then go tear a blade of grass out of the ground and observe its reaction.
