It's kinda scary isn't it????....I brought Zip and Shy up on Dad's, after Shy passed away for some reason I experimented with Purina and Friskies. But whose to say they won't have the same problem. As for feeding them raw food, just remember your cat's can get parisites from raw meat like pork and chicken and even beef I would cook to at least med-rare. Keep in mind that I don't hold a degree in catfoodtology so these are merely observations and not based on solid scientific data. (lol).....
