Cool. What kind of cages are you planning on when they hit the 12' + range? We're using custom built ones at the moment. Ultimately we're looking at something like a 10x3x2 or 12x3x2 for each snake (we have 2 Burms at the mo, a 12 footer(ish) and a 2 footer). Trouble is with cages of that size you can't really buy them, well not in the UK at least, which is why we're having to build our own. But we've built a lot of our own vivs before so it's no biggie

Besides which, you can save a #$%^$%^$%^$%^& of a lot of money by building your own
