There isn't really a direct connection. It's just to keep him from dragging it through the water, which has happened for a couple people, and making a big gooey bedding/rat ball to eat.
Also, like I said he did strike. It just didn't hold. When he struck his head flung the mouse behind him so I picked it up to try again.
I don't want to attempt assist feeding unless it's necessary to his survival. I'm getting a scale to measure weight loss but even with snakes being able to go months without eating, I'm sure they have limits too and it's possible he is at his since I have no idea if or when he has ever eaten. And he is obviously hungry.
