Back on topic, unless the filmers actually got a camera inside the "grinding" machine, we have no way of knowing what actually happened to them.
You mean the part where they stuck the camera at an angle so you couldn't see the whole "grinder"? I'm not denying that they were ground up, I'm just saying that they didn't film the entire machine.
Ugh, I hate when people contort my words. Didn't I just say that I didn't know what brands they're put into? Of course it's not baby chicken paste. I seem to recall pet food 100% of the time being more than one ingredient, like Iams dog food consists of lamb, rice, and chicken among other ingredients.
I'm pretty sure they had a hidden camera, since if they didn't they would be obvious anyway.
