Weeeelll - it might interest you to know that many petfood manufacturers are mostly owned by the big multinational human food and cosmetics industries. That's actually quite logical, if you think about it, because pet food gives them an outlet for the waste products of their other industries.
Most petfood manufacturers make a range of different foods, from the real basic crappy formulas through to at least a mid-range, if not a premium food.
When it comes to Pedigree, that's owned by Mars Inc. And Pedigree is their basic crappy supermarket food. They also happen to own Cesar, Whiskas, Sheba, Kitekat, Pal, Chappie, Bounce, Royal Canin (majority shareholder)
and James Wellbeloved (plus several other US brands). Most of those are low end foods sold through supermarkets, the Royal Canin is mostly a mid range food (though some formulas are low end, and some high), and the James Wellbeloved is a mid to high end food.
