OK, I'm from Brooklyn too. Sheapshead Bay area. about a block away from the water.
there are sooo many users of partial or full glass on this forum and the few overseas forums that sadly wont post the fact that you will be fine for now.
that said, your veiled Chameleon will outgrow the exoterra and in the summer with our 70%-90% humidity, you wont need the glass cage and may even be far better off with screen.
I used to have two panthers. care requirements were almost the same as a veiled. so how did I do it with screen?
get a cool mist room humidifier. this will add humidity to the room. you will find that you will even breath easyer.
cover the back and maybe the sides of your screen cage. I use towels instead of plastic shower curtains or tarps as they don't allow the water to drip to the bottom and as they dry they add humidity back into the cage.
on days that the humidity is realy bad, you can boil a pot of water or turn on your shower with hot water to add more humidity to your home.
get a better humidity gage. you are NOT having 15%-20% humidity in your home even with the heat drying out your house. so a digital one is needed. I buy mine when on sale at doodys on ave X and East 17th Street or home depo.
use a ton of live plants. ficus, umbrella, and pothos are great plants to use and will help keep the humidity up.
Stop and Shop on AVE X, between East 17th and 18th streets has plenty of pothos and HUGE umbrellas that can be repotted into a few smaller pots and fill out a screen cage. you can then buy the plant pots across the street at the hardware store.
buy a misting system. a Mistking or Aquazamp goes a long way to help with not only drinking but with humidity. set it up to mist 3 to 5 times per day. the first two should be long, say 3 to 5 mins. the last one long too, say 3 mins. the middle ones only 1 min for a humidity bump.
you will need drainage, so look that up for ferther info or PM me.
I keep montain chameleons now. they require higher humidity then a veiled. if I can do it, then so can you. we just have to do things that others don't have to.
PM me if you wana talk more about your new little guy and how to keep him in great shape. I also get in a ton of extra feeders at the beginning of every month and you can save on shipping if you don't mind making a local pickup at my job.
