My cham. eats like a horse, however many crickets and/or worms i throw in there will be gone pretty shortly. Lately i've been noticing that when she is walking on her vines she is much clumsier and flips upside down sometimes. She hasent fallen or anything but she will flip upside down on the vine and it takes her a minute to get back upright on the vine again then continues to walk. Is this normal or is she too fat? or something else?
