Thanks! Like I said, my friend Sherrie, actually came up with this idea for housing large adult Green Iguana's but it translated fairly easily for this big female boa.
The one thing with a walk in enclosure like this is that you have to be very aware. I'm only barely 5'1" so when I enter her enclosure Tequila is basically at my eye level/slightly above me on her shelf. If I'm refilling her water, I'm well below her in a crouched over position. This is not the safest position to be in if she took it in her mind to strike at me so in order to minimize that risk we make sure both Mike and I are in the livingroom whenever one of us works in her enclosure.
It's not that she's been aggressive but I think you're six kinds of a fool if you don't recognize the power in a snake this size and plan for safe routines.
Oh I did forget to mention it in the previous post but the total cost to do this enclosure was just around $100 I think. Really the most expensive part of it all was the pond lining but that was very well worth it to protect the floor. Boas peed BIG TIME! LOL
