I was installing a new vine in my cham's enclosure (i believe he is about 6 months old) and i leaned the screen top against one of the table legs, and let him chill on it while i did the work. i wasn't paying attention and i heard a small thump. it turns out he fell when i wasn't looking. it is only a foot to the ground, and my floor is carpeted. he seems fine and there are no visible injuries, but i'm worried anyway. should i be?
