It seems like 6 units on the Vetsulin is the magic number for my kitty Walker. He is responding with numbers in the 200s or less. The only "problem" now is when he is at 200 or lower on his morning bg test. I do not feel comfortable giving him 6 units if he is at 200 or a lower while I am away at work all day. I know from monitoring him that he can go below 100 and has gotten as low as 69. However, if I give him 5 units, his bg will go to 300+ by his supper time. Anybody have any suggestions? I sincerely appreciate your help!!
