This is just awful, but maybe some of the pet ownwners just didn't know any better. We all know how some parents cajole their picky kids to eat. I can't imagine they would have done it knowing the consequences. Just so sad! :(
You are more generous than I. How can anyone be a pet owner and not notice the extraordinary talents of their animal? If the animal doesn't eat-- its because there is a very good reason. Bad food is one of them.
