You can make fresh food available to them every day. Also, if you haven't already done so, you should go to the "care sheets" link at the top of this page and click to the one for uromastyx. There you'll find a whole mess of great websites which will answer your questions far more thoroughly than any of us can in one little post. We can send you in the right direction, but your best bet will be to read as many good care sheets as you can find.
