The cucumber and the cantaloupe seemed to do the trick!! Thanks so much for the advice. It seems enticing him worked better than forcing him. He took it on his own after I offered him the first few bits on a popsicle stick. Then he spontaneously walked over to some kale that was nearby and munched on that. What a relief! (I spent so much time shopping for Mo food and coaxing him, last night, that my own family ended up eating frozen dinners...but hey, first things first!)
To answer the earlier question: Previously, the temperature in his enclosure was probably in the low 70's most of the time and the humidity was probably very low to non-existent (I am in Southern California where it is quite dry a lot of the time) - we did not measure it. I now know better and am correcting it.
Some history on Mo: (I know you will all gasp in horror at this) We got him 2 1/2 years ago when a handyman who was doing some work on our house, asked if we wanted an iguana. He said he kept him in his truck, because he liked to hide under the dashboard, and he fed him the tomatoes from his fast food hamburgers - but that he could no longer keep him. (He also told my husband that the "iguana" was a "babe-magnet"!!) We said yes. I don't know how long he had him or where he got him, before we took him.
When we tried to find some information on him, we discovered that he was not an iguana, but rather a prehensile-tailed skink.
We kept him in a glass enclosure, 37" tall x 20" x 20" with a screen on top, and some tall branches, and a heat pad (on the outside of the glass) and one small overhead light. We also let him roam around the house a lot, when we were home, and he had a favorite spot on the couch, under a lamp. Since he seemed to do well, we really didn't think much more about it. I now realize that this was more of a tribute to Mo's hardiness than our care, and that these poor conditions have finally caught up with him, with this current illness. Now that he is getting better, I am eager to improve his habitat. (By the way, what is "hardware cloth"?)
Thanks again for all the help.
