I also found it offensive that Discovery, a site supposedly dedicated to science, seem to be pandering to animal rights activists. Why mention some rare case of abuse? You want to talk animal abuse? Look at the food industry.
As someone who worked in an animal lab and a pet store I have to say the pet industry is much worse on the animals then labs.
