You just made an excellent argument for veganism.  Maybe the woman in your story should quit eating meat, quit supporting the killing animals for that purpose and have the respect for animals and their babies that every mother deserves. What about those people who recently ate bacteria-riddled walrus meat, or the oysters that are killing people?  Mad cow disease, swine flu?  Chemicals in the water, air and ground (environmental pollutants) I could go on, but you get my drift. What about babies born addicted and/abused by their parents, suffering chronic problems and/or dying. Lots of those. 

I've been around numerous cats my entire life - including so-called feral cats - and never once had a problem. Nor do I know anyone else who has, except perhaps those monsters who think dogs and cats make a good meal.
