I would feed the snake more frequently.....start with every 7 days. Also, he probably IS freaking about being in a "huge" place now. Balled up newspapers, fakes vines, something to give him some cover. And 2 hides.
Another tip....I don't usually do this, but I recommend feeding outside the cage. Just from experience....I rescued a 13 ft female burm, who was SO not nice. Every time the c age door opened she was in your face striking. Not something I wanted to deal with. So on the advice of a long time breeder, I began using a hook to touch her before I picked her up....that was her cue it was NOT food time, it was out time. I also got a huge tote at Lowe's to feed her in. Took a few times, but she knew if she went in the tote, food was coming. After just a couple of months, I could open the cage and just reach in and get her. Just for the record, she was not rescued starving, she was rescued because they had no more room for her. I put her in a cage we built that was 6x4x2.5 and filled it up with hides and fake vines. Don't give up on your boy yet![]()
