I'm just curious, if the screen cages harm adult chameleons nails why is that all that is sold? I am looking around at different ideas so when my baby veiled chameleons get bigger I can upgrade the cage, but everything is a screen or glass which isn't good. I can't free range because we have 3 dogs and I just don't want to risk an incident. What are some things that you all have done? Do you build your own cages? Just trying to plan ahead. Thank you!
