I've only had Trix (my 3 month old panther) for a week now. I've noticed that every other night he sleeps upside down holding on to the top of his cage. To my surprise the little guy holds on all night and is in the same spot when his lights come on in the morning. Is it normal for chams to do this or should I somehow discourage it. I just really dont want him to wake up and forget where he is and fall.
