OK my cats's BG's have been in the 400's for months & we;ve slowly worked up to 7 units.. I did 7 units starting Fri night & today I started noticing a bIIIG drop!! Whoo hoo!! Now I don't know if I should give him 7 units for tonight- cuz that made his sugar go down 150 points- could I be at risk for hypo? Should I give him 4 or 5 units tonite until I can talk to dr tomorrow?
