Here is a list of things you will need/ how you care for a veiled chameleon.
Chameleon Info:
Handling - As little as possible
Feeding - A chameleon should be fed a variety of insects if possible. Feeders include crickets, superworms(not as the staple), dubia cockroaches(very easy to breed), locus, silkworms, hornworms, butterworms, mantids. These are the safest feeders. Worms should not be staple since there is a lot of fat in them but have a lot of protein. All feeders should be well gutloaded with fresh fruits and veggies unless they eat a special diet like silkworms. Most worms come shipped with "chow" that they eat. An juvenile-adult veiled chameleon should be fed every other day, around 5 large feeders or 10 small ones. feeders should not be wider than the width between your chameleons eyes.
Supplements - Rep-cal is the brand most used by people here on the forums. You will need a plain calcium supplement for use at every feeding, a calcium supplement with vitamin D3 for use twice a month, and a multivitamin for use once a month. All of these are sprinkled on the feeders very lightly. You know you have dusted too much if they look like little white ghosts

. Here is a picture of the supplements you will need:

Watering - You will need to mist you chameleon's cage 3-5 times a day until the leaves are soaked and dripping. Chameleons don't drink standing water and you should not put a bowl of water in your chameleons cage because it harbors bacteria. No waterfalls either, they also harbor bacteria. Water should be treated with reptile water conditioner. You could also get a mistking if you would like to spend the money for less work. This system is very nice if you every have to go away for the day.
Fecal Description - Fecals should have pearly white urates and brown feces. If there is yellow or orange in the urates, you need to mist more because this is a sign of dehydration. It is recommended to also get a fecal check done once a year.
Cage Info:
Cage Type - Veileds need plenty of ventilation, so a screened cage is mandatory, especially seeing where you live. Adult males should have a minimum cage size of 2x2x4 and females can have a little smaller but not much.
Lighting - You will need a regular soft white house bulb for heat, probably a 75watt with a light fixture like this:

You will also need a reptisun 5.0 long linear tube bulb for UVB as well as a fixture for that. You can get fixtures for both lights at a hardware store and pay less than at a pet store.
Temperature - You should have a temperature gradient of 70 F to close to 90F at the basking spot for an adult veiled. You should get a male because females are more difficult to care for with the clutches of eggs they have.
Humidity - You can create humidity by misting and using live plants. Humidity should be close to 100% after misting and go down to about 60% in between mistings. You can measure both temperature and humidity with a dual hygrometer. Use digital, they are most accurate.
Plants - Live plants are best to use for humidity reasons, there is a list of safe plants here on the forums if you search around. Keep them potted, do not use substrate because a chameleon could eat it and become impacted and die. Use either a bare floor or paper towels.
Placement - The higher the better, also don't put near a fan and don't put in a high traffic area of the house because it can cause your chameleon to become stressed.
Location - Location is aslo a factor even thought they cham is usually in your house. Different locations have different humidity levels and temperatures. Keep these factors in mind.
