Make sure you don't use the coil UVB bulbs....they cause eye issues in chameleons. Please use the linear tube UVB of 5.0 ....only use reptilglo or reptisun UVB bulbs. Don't use any substrate....get a screen cage. Look at the safe plant list for safe plants....pothos plants are common and cheep. Cover the soil with large rocks so the chameleon doesn't ingest it.....id suggest using paper towels to line the bottom for they are easily replaceable...make sure you have enough things for the Cham to climb on, and make sure you have enough plant coverage. If your chameleon is female....other research will be needed for egg laying ect....doooooo as much research possible between now and Tuesday....for no research = a sick or dead chameleon. And also....you got get a water bottle sprayer for humidity, and letting your Cham drink....i dont know how much you have researched....so I'm just throwing this all out, humidity for vields is 50-70% keep it in that range. Should spike to 90% when you spray and thenntrickle down.....keep posting on the forum for questions.....and of course.... Research...also. No waterfalls.
