I just searched Taobao in Chongqing and found a store called Yinta Pet Shop (also called Lingwu Pavilion), address:
No. 4023, Mianmian Street Aquarium Trading Market, Yuzhong District It's behind Carrefour, but when I took a look, the only reptile pets were frogs and turtles, as well as some reptile paraphernalia. If you really can’t find it, just buy it online!
