The best thing to do to get prepared is click on the link in the nav bar at the top of this page for care sheets, read them, and get all your supplies ahead of time online. (I recommend Big Apple Herp ~ you'll save major $$) There are really great care sheets with photos available through this site. You can also check out the
care sheet from the breeder where I got Sherbert (my beardie) from, it's here.

Quick question ~ do you have another enclosure available to use? Dragons like more floor space then height. An 18"x24" is the minimum you'll want, a 2'x4' is ideal.
Good luck ~ do you know where you're getting your dragon from?
