How can I prevent climbing on cage walls?

[Phoenix.Loperena]

So recently my Male panther chameleon yoshi has been climbing his cage walls. I was wondering if anyone knows how to prevent this. I feel he has plenty of climbing spaces so I don’t feel that’s the issue. Temperature is fine, I don’t know what it is that’s causing him to do this. Please help.

You can line or cover the screen, or get glass. Other than that they will climb the screen routinely.
