^^This, I have been feeding my boy in his cage. And he is the sweetest thing. The most he will do is go into a "strike position". I have even attempted to get him to strike at me by going straight in for him while he is in this position but he will not bite (I want to get my first bite over with haha). He must think hes a cobra or something the way he just gets taller and taller the closer I get but never hisses or strikes at me.
Now if I have presented the room with a F/T rat he will strike at anything that moves! Even the sliding glass doors while I am sliding them open! I don't want a feeding response bite though. So I would never touch or try to handle him while there is the smell of a rat in the room.
