BPs are like pickey children. Every one is different and wants different things. My spider will not eat prekilled, fully live or frozen thawed the only way she will eat is to get the rat to the pointe where it is barley alive and leave it in front of her hide in a dark quiet room for about an hour. My pastel pos het pied will only eat live. All of the others dont seem to care how they are fed, they usually take them right off of the tongs. Just takes a lot of patience and experimenting to find what the individual snake wants.
