One of the things we've discovered from the pet food recall here in the US, is that some companies are using other things, including melamine, a plastic
, to artificially spike the protein levels of their foods
And the way the labeling is here we have no way of knowing what percentage of dry kibble is composed of meat.
I do know that cats with chronic renal failure who have been traditionally prescribed a low protein diet, are really turning around on raw diets.
Bio-availability is
hugely important, and not all protein is equal. I suspect that a dog or cats body has to work twice as hard to extract the protein from plant or grain sources, which may be the cause of the troubles.
