Recently Smudge decided he just didn't like canned food any more, so I tried Newman's Own (the salmon & chicken flavor) because A) it lists its magnesium content (0.03, not too bad), B) the grocery store has it (most of theirs don't list magnesium percentage), and C) it was on sale. The only way I can get his vitamins & antihistamine into him is mushing it up in canned food, so I was relieved to see that he likes it! He's still a kibble-cruncher at heart, though - he gets c/d (an anti-crystal prescription food) and he absolutely adores it.

Love, Columbine
