Phew! I’m so very glad. While everything is important, I’m going to address the most important changes to start. The very first is that the coil or screw in uvb lights aren’t able to provide the uvb levels that chameleons need. The standard is a linear T5HO fixture with either a ReptiSun 5.0 or Arcadia 6% uvb bulb. I don’t advise any other brands as they have not proven to have reliable output. Then the uvb needs to be about 8-9” above basking area for optimal uvb levels. You have a very short enclosure and a young chameleon which will probably walk upside down along the screen top and put herself at risk for burns. To accommodate this, you’ll need to raise your lights at least a couple of inches above the screen top. You should be able to hold your hand on the screen for several minutes without it feeling too hot. Basking temp for young chameleons and girls is no higher than 80. While I’m thinking about it, let’s verify the gender of your cutie. Males have prominent nubs, called tarsal spurs on the heels of their back feet. Like this. This also shows the vertical bands and coloration that boys have starting at about 3 months old. Females will be a consistent green or when fired up, show patterns like your cutie is showing.

After having correct uvb lighting and basking temps, supplements are next in importance. You want to be lightly dusting at every feeding with a phosphorus free calcium without D3. For convenience and good health, I suggest using a combo product for D3 and multivitamins, like Repashy Calcium Plus LoD or ReptiVite with D3. You’ll use that product for one feeding every other week (or some do twice a month).
For feeding, I have to make a guess about how old your chameleon is and I’m going to say maybe 4 months. For that age, you want to feed daily about 20 feeders of appropriate size (smaller than the space between the eyes). You also need to care for the feeders and keep them healthy and well fed so that they are nutritious. Giving a variety of feeders is best and many on line vendors sell combo packs for different species. Check the forum sponsors as I believe Rainbow mealworms is one and you’ll have to check the others.

Humidity - you say you live in a desert, so you may have difficulty maintaining humidity, but there are things to do for that. While glass enclosures are great for that, they don’t come large enough for an adult veiled. I would suggest a hybrid, like Dragon Strand or Tamura designs. Check the sponsors page. *Keep in mind that ideal daytime humidity is between 30-50%. High heat plus high humidity = risk for respiratory infection. If those are out of budget, you can easily modify a screen enclosure. The easiest way is with shrink to fit window insulation film on the back and both sides, leaving the front open.
@Beman has another way with adding acrylic panels that she can tell you about. However you do it, the minimum size needs to be 2x2x4’. I encourage doubling that if able. You want to fill up the enclosure with safe clean live plants, like pothos, weeping fig, tradescantia zebrina, schefflera and others. This is a great guide for plants. Our veiled friends like to eat their plants, so look for the ones marked ‘veiled tested’.
https://chameleonacademy.com/plants/ You also want to fill the enclosure with lots of branches and vines for them to move around on. I like natural branches. I give a light scrub with soapy water, rinse the heck out of and dry in the sun. Avoid ones with sap or strong odors, like pine or eucalyptus. Being in the desert, you may have to put in a little extra to find branches. Someone there has to have some oak trees or something. Try checking with a tree trimmer or landscape company. I’m in Florida with scrub pines and palms, so every now and then go out driving to raid peoples curb piles of tree trimmings.
To attach all of these branches, vines and plants, it will depend on the type of enclosure you get. For screen it’s pretty easy and there’s Dragon Ledges
https://dragonstrand.com/dragon-ledges/ or a method I’ve been using lately is attaching garden trellis to the frame with wire. For glass or hybrid, you’ll need to create a scaffolding type structure to hang things from. Avoid wooden dowels and bamboo - the former easily molds and the latter is very slippery when wet.
