Hey, how about some pics of the new enclosure you're working on? Not sure what you're building but it'd be interesting to see some pictures on the "in progress" cage.
My monitors are all in custom built enclosures. The experianced keepers are right, if you did your research in monitors beforehand, why didn't you have the proper enclosure FIRST then get the animal? It's not as if they are rare and hard to find for sale.
That said, when I got my first one, I kept her in a tank temporaily. But I also made the tank as close to a proper enclosure as possible. I.E. I put in dirt and closed off the lid except for the basking bulb so that I could keep the proper temps and some humidity. Proper hide spots and a basking spot are NEEDED for a monitor, even for a temp set up. Even a temp cage should provide a proper environment. You don't want to stress your pet while it's waiting for the new cage.
