For a long time I have heard about old people eating cat food and crackers so they could afford their medicine.

Both. The point is survival. Leave all options open.

I couldn't eat either, because I would end up regurgitating it.

Everything loves catfood, ducks, chickens, dogs, possums turkys, guinea fowl.

So what happened to all the cats and dogs?

have you bought dog or cat food lately,,human food cheaper
