you can buy some nice looking tapistrys(spelling ?)to hang around the back and sides to help keep the heat up.
:Hi Flavia, remember me? I'm Phil's owner (Phil is the iguana who lives in the windowsill with the stuffed frog and all the pillows), and we have to move into a new place in a few weeks. I'm afraid I'm going to have to buy him an actual cage. I remember you mentioning that you got yours for $150 USD and was wondering if you could point me in the direction of a similar one. I would appreciate it so much if you could. Thanks a bunch, :-Lily and Phil :
