Hello everyone...I have a quick question, my baby Ambilobe has started to walk across his top of his enclosure more & more each day? Is this normal? He doesn't stay up there very long, but seems to like to walk across the top...from one end to the other...and then back down to his ficus tree...temps & humidity are good, he is eating well & very active. Does anyone know what would cause this behaviour? He never walks on the sides or front of the enclosure, just the very top? Thanks in advance...
