Pate is the way to go. There is a more even digestion of the protein/carbs with that texture. Going with shreds or slices...not every piece is digestion in like time. Ergo, the sugar can fluctuate. Also, not all pates get the same results. My cat cannot eat Sheba products. Her blood sugar goes off the charts. We stick with Friskies or Fancy Feast and all is well. She recently had her annual wellness exam and blood work. The vet could not believe how good her blood work was...how well regulated. However, every animal is unique and most of her schedule will come through trial and error. Good luck from Jane and Stewey
