Get a tub with a lid and put black paper covering all 4 sides (so it is dark inside) then put some aspen or any bedding in there. Put your snake in there with a live baby rat or live fuzzy (there eyes will be closed so it cant hurt your snake). Leave the room and eliminate all noise/activity in the room. I guarentee you it will eat if its hungry.
if you don’t want to try feeding live yet I would follow the instruction to warm the thawed fuzzy to trick the snake into thinking it’s a live rodent. I would do the above ^, you could probably get away without preparing a black out box and just put the live feeder in the 10 gallon overnight.
