noted!You are good to leave them in the cage. The more branches the better (ofc up to a certain point lol). The more branches you have, the less likely he is to climb the screen. Though, to counter screen climbing, you can put branches super close to the screen walls so he walks on them instead of the screen itself. As might know, screen climbing can result in nail-loss as their nails can get caught in the screen and get ripped out. And unfortunately, the nail won't grow back (unless it wasn't fully ripped out).
