2.5 year old woma python keeps rubbing her nose at corner of enclosure as though trying to burrow out. Stereotypic behaviour and does this quite a lot - sometimes for 20 minutes at a time, normally always in later afternoon/ night. Is this just hunting behaviour or something different? She has been in multiple enclosures and still exhibits the same behaviour. She rubs her nose so much the scales there have become quite dry and getting pink around nostrils. Also her frontal scale on forehead has this white mark that has slowly appeared. I have attached a photo. Is there anything I can do about this behaviour? Should I worried about the scales? Would really appreciate some knowledge and advice! Thanks This is her rubbing her nose.
