Bogertophis,
I don't want to jinx it, but I think you are right. He just inhaled a 40G weaned rat and frankly, he is thriving.
It means a lot that you, and others here, have said Katie and I did a great job with him. We did our best and he deserved that and we were able to give that. When I talk to my buddy Don Soderberg from South Mountain Reptiles, where I got Solana, he still calls Yafe the "Ghost Snake" and says he's a miracle and he's amazed by the effort we put in.
It's paid dividends though. He's an awesome snake and a real display snake. He's often on his perches and it's fun to see him out, even he's sleeping. He's also super chill and a great buddy. I think we will be buds for a long time to come.
