Horse owners in california... slaughter houses???

How do you feel about the slaughter houses... do you think they should be legal...... I think they should be legalized....before you start cussing me and telling me I'm a horrible person... the quality of life for the animals that can't be killed is horrible.. they're dying, starving, losing legs, getting caught in wire, no teeth.. etc... it's horrible... I am an avid animal, but I would rather them be put down humanely than die a long, painful death
