"Kött och animaliska biprodukter 45% (kyckling 14%)"
That means that in this package only 45% is meat, of which 14% is chicken. So in total, 6.3% of the package is chicken, and the remaining 38,7% is an unidentified mixture of "meat" and animal by-products (most likely the cheaper latter). These can be spoiled meat, dead animals, bones, blood, various food industry waste among other lovely things.
"Svenska naturliga råvaror" just doesn't mean anything.
