Tonka was pretty consistently on DM (the pate - not the "savory selects" which has a gravy base and is higher in carbs). Tonka seems to like it just fine but Teeger stopped eating the DM when it was all he was being offered - he'll eat it now that he gets a mixture. Tonka's blood sugars seem to be higher now that I'm mixing in Friskies turkey and giblets for variety (which many members here seem to feed) so either the Friskies is higher carb in Canada than in the States (possible) or Tonka is just being ornery with his blood sugars again (also possible).
I like the DM pate on paper because it has a better protein to fat ratio than most of the commercially available non-fish cat foods, but liver is the first ingredient in DM pate, and that seems like a Lot of liver to be living on...
Note: I've seen a couple different carb ratios for the DM pate. I can't remember them off hand, but one ratio is about the same as the Friskies turkey and giblet, and the other is a few percent lower, so it might actually be a lower carb food (here, in any case)
