Has anyone here used the lantus pens for dosing their cats? I'm curious since I'm following instructions on the pens - change the dial to the units (2 for my cat), insert the pen needle, press the button & hold for 10 seconds. However, after pulling out the needle, I get 2-3 drops of insulin out of the needle... Does this mean the needle isn't working & I'm not really giving my cat anything? Or is this normal to see some drops afterwards? I know the pens hold 3 mls & each ml has about 100 units in it, so what I should be giving my cat is barely a couple of drops... Thanks!
