Most commercial cat food has actually about 4% meat. This is for nearly 100% carnivores. They put soya protein shit in instead, plus carbohydrates (to make our cats fat).
Its really a scandal. And one I've only noticed because I've got a lovely little kitten I want to feed well.
Apparently this commercial cat "food" makes them hungry all the time (no real meat) so they overeat (diabetes) and it also makes their pooh pong when it doesn't need to, it makes them less energetic and their coats not so shiny!
Does anyone else wonder what planet we are on when our 100% carnivore pets are fed 4% meat by these bstd manufacturers? Its not even cheap!
