I present the room an hour before every feeding.
He is an 07. I don't know his current weight but he was about 430 grams when I bought him back in early February.
I am pretty sure sure they were feeding strikes. Usually with defensive strikes he snaps and retracts his head. ( he nipped me when I first got him) For these strikes it looks like an all out lunge.
He is not in shed. He just came out of his shed this past Sunday. That is the reason for only three attempts in 4 weeks.
I am feeding him in his tank but I usually remove most of the furniture to make it easier for me to watch and give the mouse/rat less places to hide.
