I just started my kitty on insulin today. 1/2 unit morning and night. His before shot BG was 365 and it went down throughout the day until 3:00pm when it was at 197 then it was betweeb 219 and 210 before it dropped to 146 at 9:00pm. I didn't realize, since I am new that I shouldn't have given him the shot, 1 hour later his BG was 127. I'm worried it is falling too fast. I was advised to give a couple teaspoons of his old food to try to keep it from falling too fast. I gave him the food and will be rechecking at 11:00pm. I will be up all night with him and am concerned I won't be able to get advice if his numbers continue to fall since it's so late. Any assistants will be greatly appreciated. Thank you. My name is Cathy and my kitty is a 13 year old Russian Blue named Simon.
