There are some who believe one way, and some who believe the other, it really just depends on the individual.

Some people do take it to the point of saying nature itself is messed up and do stuff like try to turn their pets vegan or vegetarian http://www.vegancats.com/ http://www.vegsoc.org/info/catfood.html

But there are plenty of vegetarians who don't take it to that level, and just are not eating it due to the cruelty animals raised for meat face as you mentioned.
