No I don't have a drug habit

My cat, Bouchee, is diabetic. He needs to be stuck with one of these syringes twice a day for his insulin dose. He's fluctuated for about 3 years while we tried to get him on the right dosage, he's pretty stable and happy now on 4 units twice a day (5am and 6pm). That's four lines on the syringe.

He's so used to it now, that he makes a little meow if we forget to give it to him after he eats.
