For the third time in a row it seems that male bp is having trouble feeding. So now it has been about 4 weeks since he last ate. During that time, temperatures have been good in his tank, he had another perfect shed and pooped twice.

This is why I think he might be having problems seeing:
on all three occasions he has followed the scent of the live food item (tried mouse twice and small rat once) to the point where he is almost licking the rodent. Of course when he gets that close, the rodent gets scared and runs/jumps away. I have even seen him miss on what should have been an easy strike.

What do you think is wrong?
Has anyone seen this before?

I figured that if he was stressed out he wouldn't even attempt to stalk his prey.
