I have kept all kinds of snakes native to Texas as well as Corn snakes (just love the little guys and the colors you can get), several lizards, a tortoise and even some hot snakes (venomous). The Kingsnake.com forums are great for herps and especially graybanded kings, if you ever get into them.
Elgecko, just aword of advice: Panthers are beautiful chameleons but they are so hard to acclimate and stress at the drop of a hat. In the herp shop I used to work in we had one that only ate for one employee and turned black (stressed) anytime anyone else was around, so Mike eventually took it home. Those guys are super sensitive in my experience and need a quiet room with very little activity around it. Just a heads up.
