Maybe it's not eating horse that we have to get over.
It's likely that if we get over it, then folk will start farming horses and personally, I'm not very comfortable with that. Although the way some breeders turn out foals with no visible ridiing horse market seems close to that anyway.
Maybe what we need to get over is the stigma of saying "I can't afford this horse, I'm going to have it slaughtered". The cost of keeping horses is a high - even for well intentioned people, circumstances change, they can't afford to keep the horse so it gets neglected or sent to a rescue centre (if a place can be found).
My Shetland has been diagnosed as probably having Cushings. He's 13. He's had blood tests today and we'll know on Tuesday. Medication is around £1.50 per day, £550 a year. He could live another 10 years. It's a tough one.
