My BP is the same way. I fed him last night and he was in hunting mode tonight when I changed his water. I can reach in and get him but if I offered a rat he would take it, no question. He stays like that at least 2 days, relaxes a few days, then he goes into hunting mode again on the 6th day.
I think it’s linked to feeding him prey that is to small. He should be eating small rats but I’m feeding a surplus of weaned rats that I ordered last fall. I always underestimate what he can take as a meal. In your case, I would try converting him to rat pups and then in a few months go to weaned rats. One feeding is MUCH more convenient than 2 mice and it will be easy to convert him if he is always hungry like mine.
