We've never bought a can of cat foot, always the stuff in the bag. My parents have had cats for years on the farm and they eat table scraps.
I worked reatil through college and one of the cashiers was in tears one day when her shift ended. Someone wanted to buy dog food with food stamps and the law won't allow it. So he went back and picked up a big steak and brought it back through her line and paying for it with the food stamps stating that his dog was going to eat better than she did now.
