my b/p roswell has been fasting for a month to a month and a half. when should i start to worry? i have left him in his feeding box with a lid on top for over an hour. all he does is cruise around and ignore the rat. when i dangle the rat around he does strike at it and wrap around and do the whole bit, but after that he just doesnt care. should i try a p/k one.. maybe he is sick of the f/t? he doesnt look like he lost weight or anything, he looks overall much the same as always, when should i start to worry?
