OK! So they're more like big dogs or even my ball python female that way. I thought my ball python was "grown" at two, but at ten years old she's MUCH bigger than back then.
In that case I'm going to give Noel 12 square feet or so of cage space in my plans; I'm making two towers that will bolt together with a corner piece so I can divide off some units or double the size of others. I'll keep Noel in the 6 square foot unit for now, but when he grows I can open the other side unit for him.
Is it weird that I'm actually relieved my boa is nowhere close to adulthood? He has my absolute favorite personality of all my snakes and I'm glad he'll put on some more size. There's just something about holding a big heavy bodied snake in your lap while watching TV that I love. He's on the schedule his previous owner suggested for me of one rat just big enough to leave a lump every two weeks. Is this about right?
