Welcome!
Hi there,
well im glad you are trying to learn about veiled chameleons, nd here is a great place ot get IMPORTANT info so that your new pet will live happy and healthy....
so a vieled cham you say.....hmmm, at a pet store....well becareful cuz most pertstores dont care of chameleons that well, and you mite b getting a sick cham out of nowhere....pictures of the cham would help if he is ok.....and let
to let you know that male veileds have a spur on the back of their feet t show its a boy (bump on the back of feet).....if there is not bump then its a girl cham...and female veileds lay infertile eggs (can lay eggs without mating a male cham)....they will be infertile (they will not hatch, empty eggs so to speak)...
ok....glad you got the reptibreeze for the cham
you need proper lighting a heat bulb about 40-60 watts regular hardware bulb for heat, put it otop f the cage at a corner for the cham to have a basking spot.....not in the middle.....(basking temps should b 78-85 degreed MAX) dont let it get too hot, or else your cham will burn....get a digital thermometer to find out the temperature around the cage...everywhere else should b in the 70-75 degrees range
you need a LINEAR UVB tube (Repti-Sun, or Repti-glo 5.0) not the coil bulbs, helps with keeping him healthy by not getting MBD (metabolic bone disease) and such...
so both lights one basking and one uvb are on top of the cage, leave both on for about 12 hours on and 12 hours off...turn off the lights at night...they sleep at night....
you need to give water by a dripper and misting the cage and your cham

...they do NOT drink from a bowl, they lick of the waterdrops from leaves, so get live plants too (safe plants are ficus, hibiscus, and pothos plants), so mist 3-5 times a day for about 5 minutes each or more....
they eat bugs,when you get the bugs gutload the bugs (feed the bugs healthy friuts and vegeatbles except tomatoe , spinache, and broccolli)... get small crickets like 3/8 inch or 1/4 inch crix size, and maybe some flies you can order online....also silkworms, superworms when older, hornworms, butterworms, dubia roaches, etc

not recommended to get bugs outside that mite have pesticide on them and can kill your cham......
do not get any substrate or put stuff on the floor on the bottom of the cage, leave it empty or add paper towels to soak up water when you have the dripper and misting...
and you need supplements
i use (example)
rep-cal without D3 (most feedings)
repcal with D3 (2-3 times a month)
herptivite (2-3 times a month)
feed your little guy about 8-12 little crix during the day, that are no bigger than the length between his eyes (general way of knowing what size bugs to fee your cham)
i hope this helps, i know i mite of missed some stuff.....
But dont hesitate to ASK questions
thats what we are here for and research on the forums too
goodluck
