Hello, I hope you and your fur babies have all been well! I need help for Theodore's blood sugar/insulin please. Teddy has not needed insulin for his diabetes since about May of this year. The change in his food made his numbers stay within normal range is what I think. (He has been really unwell with nerve pain and loss of the use of one front leg) However his diabetes has been stable. Well, within this week he changed to Perscription Hills K/D canned food because my vet said his kidney numbers are at the highest before kidney problems. I always check his blood sugar randomly ever since May.... the last two days he peed outside his litter box...something he has never done except when he had diabetes before he was diagnosed. Well I check and his blood sugar was 384 on the human meter. (It's possible he had eaten some of his food at any point in the hours prior to me testing him) - but I decided to give him 1 unit of insulin, since I'll be home with him....and he ate (back to his old low carb food) and an hour later now his blood sugar is 468. Why is it going up?? I've never seen a number that high! I thought since I gave insulin it should be going down?? Should I give him more insulin? What if it goes up higher? I don't know what to do?? Please help...thank you!
