Hey, as the title says my snake keeps trying to escape. Attached are photos of his new setup now it's all sorted, I will be getting more greenery to fill space, that's just all the petshop had at the time. I upgraded his viv last Saturday and I feel like he's struggling to get used to it, there's an extra foot and a half of length on the Viv and I've seen him exploring. I kept his cave and decor from his old Viv and spread it out so it had a familiar scent, I'm yet to feed him in it because he was fed only a few days before moving (I wanted to make sure he ate because I know change can make them go off food for a bit) but he keeps rubbing his nose in the corners of the glass and along the edges of his enclosure, there's a hide either side, plenty of logs and other places he can hide, and some fake plants in there. I keep his heat between 26-34⁰c on the warm side and his cool side averages 22-26⁰c depending on time of day and I mist his viv twice a day to keep the humidity 65%+ (last few days had been hovering around 72%) but today I got home from work and found it was open and after tearing the house apart I found him under the sofa. He is now safely back in his viv and I've turned the heating up a bit so he has a chance to warm up. I've now padded out the gap between the glass panels so he can't escape again tonight and will be going and buying a lock in the morning along with some more decor so he has more to hide behind but I'm concerned because I've had him 11 years and he's never behaved like this before. He's escaped once before and that was only because the glass was left open slightly after cleaning by mistake 

I just want to know if there's anything else anyone thinks I can be doing to make him more comfortable, of if you've had this happen with you before how did you handle it.
