I recently adopted a Mali Uromastyx (the owner called her an ornate, but I'm almost 100% positive its a Mali). The former owner had her caged with a full grown beardie, and she literally never moved. He said she ate two or three times a month, and was fine on that.
I put her in a 20long, put magazine paper for temporary substrate, a small cell phone box for hide, and a medium driftwood toy. For nearly a week, she was all over the place. She ate every bit of cabbage, lettuce, carrots, and crickets I put in there. She danced around the edges, flirting/fighting with her own reflection. The previous owner said it was 100X the activity he got out of her.
I kept her hot end between 105 and 125, and cool end around 80-85. About 6 days with her on magazine paper, I put about an inch or two of sterilized play sand. She dug around for a day or two, and then found a nice cozy little spot under the corner of her toy, buried in the sand. She hasn't moved nearly as much the past few days, when I'm watching...but is obvously eating her food, and leaving lots of footprints all over.
When I first got her, she was dull, with a few light spatters, and a spray-paint pattern of yellow around her edges and belly. 8 days into her staying here, I took her out to find new, bright orange on her face, some on her back and belly, and underneath her tail. None of this was present when i got her. I can only assume this is a good thing?
I've also heard that occasionally feeding her crickets can be a bad thing?
Anyhow, she seems uber happy now. I'll get her out at least once a day (to get her used to being handled). She'll just chill on my chest and watch tv with me for half an hour. 
I plan on building her a tank with MDF and screen...any suggestions? I could also use some tips for food variety, vitamins, cricket exposure, and husbandry.
Thanks,
Brendo
