Newmarket OSPCA in the Business of Murder?

I went to the Newmarket O.S.P.C.A shelter website this morning. I was shocked that there was no information or announcement concerning their latest decision to euthanize hundreds of animals rather than treat an infection that while highly contagious is not a death sentence if properly treated. Since when is the O.S.P.C.A in the business of convenience killing? This agency that has sworn to protect the lives of these animals is now their executioner, and for no other reason than the fact that they have allowed a situation that could have been prevented to get out of hand. How does an entire shelter full of animals contract the same disease if things are being run efficiently? Are these animals not vet checked vaccinated and de-wormed when they are brought in? If they are not someone explain why? How is it I can rescue animals in my own home, and never have an incident like this take place? These people are supposed to be in the business of saving lives, not ending them because of their own incompetence. I think that the O.S.P.C.A should be put under review, the shelter should be closed to the public until all animals have been treated and are declared healthy. The O.S.P.C.A should not be allowed to follow through with what in my opinion amounts to mass murder!
