Alright guys, I want to hear your thoughts on this one.

I have an albino pied ball python who is about 3 months old. He has been a bit finicky with eating since I got him, but nothing that a switch of mouse to rat didn't fix. Temps are good and humidity is in check, I have 2 other bp's running on the same temps/bedding/etc. who are totally normal and eat like champs. Anyway, last time I fed him was about a week ago I saw that he had a piece of forest floor bedding stuck in his mouth after swallowing the food, so I removed that after he finished with the rat, but since then everything has been normal. That is until today when I attempted to feed. He immediately responded to the food and went up to it but didn't take the bait. Eventually he started to move his mouth while directly in front of the mouse, almost like he was realigning his jaw, except it was a bit wider than normal. After he tried this a few times I decided to put the mouse up to his mouth just to see what he would do, and he immediately curled around it as if he struck it himself and eventually ate it. I am wondering if anyone has had this experience or if they knew what may be going on. Thanks for your help
