clutter up his enclosure. Fill it with more hides and crumpled up newspaper then watch for the day he is in his hide with his nose sticking out. That's a sign that he is ready to eat. I have a major problem feeder too. I got him when he was a year old and only 100g. He didn't eat anything for the first 3 months. I finally got him to eat a mouse hopper but then he went off again. Til recently he would only eat one or two mice every other month and in that time I tried EVERYTHING! One day I just decided to clutter the crap out of his tub and bingo! He's been eating every week for the past two months. I even got him to eat an ASF so this week im going to try for a rat pup
