"I'm afraid that the Trophy representatives is telling you a lot of inaccurate information. The idea that cheap pet food is filled with claws, beaks etc may have been the case many years ago (and is still the case in many countries) but under EU pet food manufacturing regulations pet food has to consist of food fit for human consumption."

Can I ask whether pet food has to consist of ingredients fit for human consumption or whether the ingredients must have come from an animal fit for human consumption.

A beak can still come from a human grade chicken althought beaks themselves aren't fit for human consumption.

I was under the impression the animal must be fit for human consumption but the cut of meat put in the food is not necessarily the same stuff you would get in sainsbury's. The scrag ends left are still from a chicken fit for human consumption but not necessarily a great quality of meat left once we've nicked our bits !
