I am beginning to hate the size of our new cage. He was fine the first few days in there until today. He has now decided to keep climbing on the screen and he has falling twice from half way up the cage and twice from the top of the screen to the bottom which is a 4 foot drop. He appears to be fine, he just gets up and climbs back up again. I think we have enough for him to climb on in the cage so I am unsure why he keeps doing this. Every time I hear a thud, I am scared to go over and look at him. Any help would be greatly appreciated.
