Also, have you tried holding the f/t prey at the shoulders in front of the snake? Instead of hanging the prey above? Hanging from above tends to make the prey look larger and could be intimidating to the snake. I just recently switched a 10 y/o BP to f/t and he ate live his entire life. As the other posters suggested, head the prey with a blow dryer prior to feeding. I had to heat as many as three different times before mine finally took. Works like magic :)
