Bearded dragons are surprisingly easy to set up a cage for, once you've got hold of a suitable
bearded dragon cage.
They require heat from a heater and light from a
lighting setup and then you're well on course.
The "bedding" or substrate as it is usually known in reptile circles - that is the material covering the base of the cage - should
be something light weight, easy to move around (so you can clean it easily), safe if it is accidentally eaten by your bearded dragons and
to my mind, something light in color that mimics the substrate in a dry region such as the desert.
A few options for you are:
Reptile-Safe Sand - reasonably heavy, but comes in a variety of colors and has lots of minerals in it if eaten by your bearded dragon
Walnut Chips - as it sounds, chips of walnut. Lightweight and reasonably priced, and my personal preference
Once you've got this in place you should look next at adding some rocks and thick branches or pieces of wood to the cage to give your bearded dragon(s) something to climb on.
When you're arranging them, you should be looking to ensure they look aesthetically pleasing, they are safe (won't fall over and damage your lizard) and provide somewhere for your lizard to hide just incase.
Apart from a
waterbowl then, you're all set.
And now you know exactly how to set up a cage for bearded dragons :-)
