When I was a child, I used to eat the milk bones that my mom got for our dog, and she said it would not hurt me, but was not a good thing for me to be eating. I also tried crunching on a few of the chunks of dog food that we fed the dog, but I was mt impressed with it enough to want any more of it after a few bites. I guess my mom just figured since it would or hurt me, the best thing was to just let me get it out of my system, and try some.
Once she told me that they made dog food out of horse meat , and I loved horses, I never ate dog food again. Now, even dog food is just made from mostly chicken scraps from heads, feet and feathers to the insides, so I certainly would not want to eat it, even if it is cooked and processed enough to be safe to eat.
As for the man that ate the canned cat food, I go along with the idea that he knew what it was, and pretended that he did not. Even if there was not a picture of a cat, he still had to be in the pet food section of the store to find it, so it is pretty hard to believe that he didn't know .
