They ramble on about calcium, phosphorus,
nutrients in the food, all of which can be sourced from garbage, and

Well, shouldn't we be? Kidney disease is a MAJOR problem in cats, and yet you

Why on earth do they
think the pets are suffering from so many ills. Could it be from the
garbage we are feeding them?

back up what you allege.
