The second does of deworming meds for my snake, I need to use a syringe... I have a few, but the tips are so thick I couldn't slip it under his lip...

What kind of srynge do you use for you snakes, and how do you get them to open their mouths?? How do I do it without hurting him, and without hitting his glottis?

He's nice and cooperative, doesn't get too bothered by it, I just don't know how to get him to eat it.

Thanks
