For some reason my ambilobe yoshi likes to climb up and down the screen and sometimes he slides to the bottom i am worried about him ripping out a nail is their a way to prevent this?
My veield was doing the same thing. I moved the vines around so that it surrounds the walls, always giving him the option to use those instead of climbing the wall.
I had the same problem as you, my chameleons nails became chipped, so I out plastic sheets on three sides of the enclosure except for the door, And then I put plant climbing frames over the sheets so he could climb on them
I had the same problem and did what BC did, stuck a bunch of plastic vines,
leaves, and wooden birdcage ladders on the inside wall using some tiny wire ties.
Problem solved
