First, I have done plenty of carpentry, and very handy with power tools, and have all I need to get this project done. Of course, the hard part for me is finding out exactly what's right for the Iguana, but researching and finding out BEFORE i make any mistakes I won't be able to reverse. I understand enclosures should be taller than wide, but My Iguana is only 12 inches STL, so I'm going with a 4 x 2.2 x 4 enclosure, which I've read is good for Iguanas close to 3 ft long, so this will last him for a couple years I'm hoping, until it's time to upgrade. Here's the initial frame work, like I said just getting started. Placing the Linoleum flooring just to get an idea of how it'll look. The 3-4 inch space under the flooring, of course is mostly for support (it's not finished, just getting a rough idea. But I also plan to either add a place for a pan to sit in, or add my own pvc drain system for his bathing area. I've already circled out a couple places for light/waterfall electrical outputs to go through some parts, I'm using computer desk Grommets, if anyone has any better suggestions for this, i'm all ears. My Iguana's name is Krycek ( x-file fan, lol) ... I actually hated that I missed the opportunity to name him Yoshi, but after looking up Ig videos on youtube, found out it's a pretty common name for an Iggy. Here's the enclosure he's in now (18" x 18" x 24"). I just feel bad for him cause there's not much space for great decoration ideas, or many different climbing options, but he uses all he has available to him. And, here he is enjoying an afternoon snack, which I have recently placed the feeding dish lower in the habitat, closer to his water tray. I'm just ready to get him some more space, and not planning on building the greatest habitat ever, just something to get him much more needed space to last him a couple years; with a few personal touches for easy convenience in cleaning, etc. I'm going to have many questions along the way, so hope some experienced habitat builders can lend a hand along the way. Already met some great people here, and received much appreciated advice.
