Okay, so I have a 3 year old jungle python. He’s starting to outgrow his cage so I’m getting him a new big enclosure tomorrow. He’s currently in this (I actually don’t remember the specs too well). It just feels like it’s getting too small for him. The upgrade will be 1050mm in length, 1200mm wide and 620mm depth. He’s always stretching out and exploring his enclosure like this So not only do I want extra space for him since he is growing, I also want it to be environmentally enriching for him. Obviously not the same way you’d do that for a dog or a cat, but give him a few branches to stretch out on and a choice of 2 or 3 hides. He’s generally a really bloody stoic snake. Nothing really freaks him out. Didn’t even bite when he was sexed and damn that’s gotta be uncomfortable. Basically, first and foremost, I’m asking what are your thoughts on what I’m trying to do here? I want to do the best by my animals and I find I need reassurance sometimes and sort of confirmation that this is a good thing to do. Secondly, if he does happen to get stressed, are there any other signs that show that, apart from resisting food? If I put him back in his old enclosure, will he settle down again? How can I ease the transition for him? On a complete other note - what substrate would you recommend for an enclosure like that? I do feed him in his viv so I don’t like the idea of him easily ingesting substrate.
