as for the other post - just making a comment that if a snake is hungry enough, it will eat whatever small living thing you put in front of him... guaranteed.
Sorry, But this is completely wrong. BP's are very picky. Some will only eat ASF's, some rats and some mice. Some BPs wont even give a mouse any attention, let alone striking and consuming it.

Another example are JCP's. Many JCP's wont make the switch from mice to rats. It doesnt matter if its just moving. You can wiggle your finger in front of your BP and it wont strike unless its been scented. Its not just about movement with the snakes. Its about scent. Some BP's will wait for that special chemical sequence to be brought to their jacobson's organ until they decide they want to eat the prey.
