Most dry cat foods resemble human breakfast cereal; that's an indication of
how much carbohydrate they contain.

With regards to fat in cat food, Eukaneuba dry cat food has by far the most.
There was a thread in this newsgroup about 5-6 years ago about fat in cat
food. Cats can deal with saturated dietary fat much better than humans, so
don't get too upset about that. Actually, it's probably better that they get
their energy from dietary fat than from carbos; easier to digest and burns
slower.

Is there a trend of increasing pet population? Is there also a trend toward
more carbohydrate in pet food? Is almost all of the available "waste"
chicken/turkey/pork/beef/lamb/fish meat being rendered, or is much of it
being discarded that could otherwise go into pet food?

Suppose there are no more "waste" meat parts available to add to processed
pet food. Are you willing to pay a *lot* more for pet food if animal protein
content in pet food were to be increased by inclusion of meat parts that
previously could be marketed for human consumption?

Think about the impact of what your movement will have on the economy. On
the downside, it would probably cause both pet food and people food prices
to go up.On the upside (?) it would cause pet populations to stabilize or
decrease, as the cost of pet care goes up.
