palominolover- "so you just want every single horse to be adopted, the horse shelters don't have enough room. So they need to slaughter some.": Which brings me to another problem: overbreeding for horseracing, PMU, etc etc etc. Not to mention, if you ARE going to result to killing the animal, could you not do it in a way where the animal's life doesn't end in fear? I have had to euthanize many horses and they were always VERY happy and calm up until their last breath, not screaming and trying everything in their power to escape.
Sissimut-icehestar: I don't know anything about slaughter for where you live, this video is based off of illegal US slaughterhouses.
Also I'd just like to add that when it comes to horses being neglected in someone's backyard, starving to death, slaughterhouses can be preferred. I'm just not for either one (and by slaughterhouses I'm referring to the inhumane ones, as I know nothing about the humane ones)
