I havent heard of peta killing but I don't think peta would have killed the ones who were healthy. To be honest it just emphasizes the point of unwanted animals being bred. I would obviously prefer no animal be put down, but I would far prefer that if because of funding issues, and being inundated with unwanted animals that can't be rehomed, it is better to sacrafice as humanely as possible, the lives of those who are elderly and infirm..than to continue life at the expense of many other animals who arein need of rescue form horrific conditions. On a down side of peta, as a horse owner, I too get annoyed at the comments directed to horse ownership; a lot of thier members don't appear to differentiate between good kind responsible ownership, but blanket us all together. But still, I would support peta, they are doing a thankless task on behalf of a lot of animals who can't speak out for themselves, and that is something that more people need to do.
