How old and how big? Pics would definitely be beneficial in posts like this, however I have baby boas that are a little over a month old. I gave them a day or two to settle in and started them on fuzzy f/t mice (all my boas eat f/t), one of them takes them like their going out of style and the other takes some enticing sometimes but eats every time too. Maybe try putting the snake in a small bin or paper bag with a f/t fuzzy and leave it alone for a little while and see if that helps? I have a couple boas that won't eat without privacy, from what I've noticed with my baby boas is they won't eat if the prey item is way too big for them. Good luck hope this helps you a out little and post some pics lol
