I gave him a different can of food but I did the carb percentage and it’s still low carb, and that was last night.Hi Kayla,
Have you tried a new food lately? Sometimes a particular ingredient can spike BG levels in some cats (e.g. soy protein), even if the food is low carb.
Sometimes an upward trend might be due to a rumbling health issue. Most obvious things to get checked out are potential UTI/other infection or issues with teeth/gums.
