Most likely the next reptile I'm going to get would be either a Yellowbelly Ball python or a Mali Uromastyx. I just had a few questions on the Mali..

I'm thinking of getting a subadult, so what are the prices I'll be looking at?
I read that they can have bird seed as substrate, and the Uromastyx at my volunteer job are on bird seed, so what type of bird seed should I use and where can I find it? (I would imagine petsmart)

Also, what type of vegetables can I offer daily? If I have anymore questions I'll be sure to post.
