>Go to a rural village in a developing country and you will see them using 95% easily.

Using 95%? Sure.

We will have to define what is "meat", in pets food a lot of parts of the animal that wouldn't be considered "meat" are used.

And there are some Laws/rules about some parts not being fit for human consumption (of course depending on the country).

If you boil meat to make broth and then throw out the chunks after some hours, you have pulled most of the nutrients into the broth. So, yeah, I would say they use most of the animal.
