I would get in touch with your breeder to return her. If you bought a male panther you should get a male panther. Females while still awesome, are more work, live shorter, and are not as colorful especially in panthers.
Why not re screen it? I re screened my brand new cage and put in stainless and larger mesh holes screen cause i was afraid of my chameleon losing claws in the reg screening. Its pretty easy to do and most hard ware store will do it for you.
I have a veiled also with a similar schedule
8am lights on
8:45am mist 1 min
10:45am mist 1 min
12:45am mist 2 min
2:45pm mist 1 min
4:45pm mist 1 min
6:45pm mist 1 min
8:00pm Lights off
In fall/winter I make misting 1.5 mins as the air is dryer
Why the 10 sec mist at 8pm? does bump humidity...
