what are you using? live or f/t? how long did you leave the prey item in the enclosure?

normally when they stike and miss... they try again shortly afterwards so if you just kept holding the f/t item or left the live in the enclosure, it would have taken it.

now that said, my ball and boas won't let me hold the f/t prey item because they'll only eat once i'm gone from the room. so i set the prey item near them, lock up their enclosure and leave. if they haven't eaten it in about 30 minutes... i reheat it and try again.
