Great cage! Must have taken you a long time and a lot of effort to build!:):D:):D I wish it was mine :( Those lucky chameleons. BTW those chameleons are beauties. I wish I had them too.
Just keep on offering it crickets, this happened to me but I fixed it. Is she/he shedding? Because when they're shedding they tend to have less appetite.
What I do is I give it calcium without D3 almost every feeding, and twice a month I will give it Herptivite, and then also calcium with D3 is twice a month.
