Cat Diet Question
I was pondering the feline natural diet, rodents, birds, other little critters. Now in the case of rodents and birds, wouldn't cats ingest a fair amount of grain and seeds because that's the diet of their prey?
So why are grains in cat foods considered bad, is it because they are processed grains, unlike those contained in bird/rodent stomachs? Or is it because many foods contain too high of a grain ratio? Or maybe both?
