Animals raised for their fur or meat are, we would hope, killed as humanely as possible, not made to suffer through long hours of vicious biting and clawing.
But if you are going to stop raising animals for entertainment, what about race horses? They are bred for one purpose, so humans can gamble and be entertained. Even worse, what about circus animals? There are many animals which are treated poorly, if not inhumanely, by mankind. This doesn't necessarily imply that they should have "rights." It only underscores man's inhumanity.
