Thanks for asking. Unfortunately, where we live there are no vets that have any expertise or knowledge with reptiles, so we're doing our best for Irwin by implementing most of the wonderful suggestions from you all. We changed the substrate and lighting and we've made the dietary changes as well. He seems to be doing well. The swelling has gone down noticeably on one of his back feet and the coloring on his other feet looks more normal although there does remain some swelling. I hope that in a matter of time, we'll see real improvement. As I said earlier, he is acting completely normal as far as his eating, movement and general demeanor, so we remain very hopeful. Thanks again for all your help andf I'll keep you posted on his progress.
