Today I switched Bailey from Sheba canned cat food to M/D canned. I mixed Sheba and M/D like recommended to eventually get him on M/D only. Morning BG postprandial was 323 2 units given,lunch postprandial 187, and dinner postprandial 672 2 units given. His evening BG has never been this high. Did I mix too much of both foods together? Should I just use M/D and not try to slowly mix Sheba and M/D together until we eventually are only on M/D?
