He has now eaten again after another 5days and seems calm and content so hopefully he just had moving in stress and all is fine now 😀.....
I have to say after reading your post that sounds like animal cruelty to me! Yes I'm a reptile beginner but a massive animal lover. And as far as I'm concerned leaving your snake to go hungry for all those months before you decided to do something about the husbandry issues is not good enough nor is covering with a towel and not allowing the poor snake to see the light of day for two months!
Im glad i moved mine back into a small tub when I did as that way he didn't go without food too long. I will put him into a viv when he is a little bit more older and settled.
