At the very least, please give this article an appropriate title. Some of these foods are poisons, and some are only problems in vast excess. Others, such as eggs, are fine to feed, and the vit B in the yolk far outweighs the defiency from whites. As someone else says, raw bones are soft enough not to cause cats and dogs a choking hazard (cooked bones are dangerous), and act as great tooth floss. I count myself among many raw feeders in the UK whose cats (or dogs) have raw meat diets that replicate what they would eat in the wild. Chicken wings keep their teeth clean, eggs keep their coats glossy, and the exercise of chewing meat off a bone keeps them occupied and content.
