I would have to agree with every one else even baby BP's can go a long time without food you need a scale and monitor the snakes weight to determine if it has been to long since it ate by weight drop. If you are force or assist feeding it needs to be pinkies or fuzzys definitely nothing to big. Try live hoppers if the snake doesn't take those wait it out a lil while get all of your probes down on the snakes level so you know what temps the snake is getting. I can assure you although all of the information provided says your doing the wrong thing don't get discouraged every one here is trying to help. You do need to make your BP feel very secure to get it to eat and if moving it to a smaller tub with an UTH is not on your agenda at bare minimum clutter up the cage more fake plants from the craft section at walmart are cheap wash them well first but it will help your lil guy feel more secure and not so exposed also the cereal bowl idea is great another good one is the cheap disposable snack bowls in the baby section it may seem small but a lil guy like that likes his hide to be snug around it. Also for holding in the humidity and some of the heat layer foil over the larger open sections on the screen and then you can tape them but I recommend hot glue it is much safer than tape. Another thing you can try after letting him be for a week is to try dangling the mouse and if your BP doesn't take it try to put your f/t mouse on a lid and set it in the cage in front of the hide and walk away shut all the lights in your room off and check on him in an hour. Another thing we have found helpful when the little guys are refusing is to make it more tempting put a small hole in the mouse stomach so that some of the blood seeps out on its fur always works for our younger stubborn BP.
