Glad you brought that up ~ here we have a big animal bred up from far smaller animals ~ and now we should treat it like we do all big animals ~ and we have people who imagine that big animal is like a little Bijon Fries or something ~ yap yap
Get something straight. Starving horses are being neglected, they are not the ones headed to slaughter, particularly slaughter for human consumption. Slaughter buyers don’t want bones, they want nice healthy fat ones - heavy ones... the bigger the better.
The existence of slaughter as an option has not, and will never, have one effect on people who are neglecting animals. Slaughter as a necessary solution to neglect is a myth... and a red herring.
