the problem is, it is hard to get good color rendition using any sort of indoor light or flash, but based on the last picture i would say that she is likely gravid. that being said, i notice that she has been getting her nails stuck in the screen. this is a common problem, but not one that should be taken lightly. losing even a single nail, can potentially cause an infection that can lead to worse problems, and any sort of infection, could cause problems for an upcoming clutch. i also notice that the uppermost part of the cage is fairly devoid of climbing structure. you might want to consider adding more structure to the more open parts of the cage. most arboreal chams, are significantly more at ease, when they are above eye level, so she might be less inclined to cage crawl, if her basking spot was above eye level. if none of those things help, you may want to consider rescreening your cage (fairly easy) with pet screen, my favorite is, super pet screen by st gobain fabrics. most pet screens have a rubbery plastic coating that is less snaggy on the nails. i could send you a swatch if you just want to check it out. jmo
