Do you use turtle drops in the eyes like once a month or every other month? I had an eye issue from the day I got my chameleon from petco I took care of that and have used the turtle drops and haven't had eye problems since. An old breeder told me about the drops was good advise for me.
1-1.5 is great for me, humidity is on the the mark and my cham is hydrated (granted I haven't seen her drink) her poops are always white. Drainage isn't an issue for me sine I don't get puddles.
I don't like crickets escaped in cages. I've read horror stories of Chameleons being mutilated by crickets at night eatings eyes, and what not. I will always cup feed or hand feed them and free range other feeders.
That depends on your set up and the humidity in the room, also some species like montanes need more humidity which is usually more mistings for longer periods. I have a veiled that doesn't require all that much misting to keep humidity between 40-70% and since the room humidity usually around...
