I just purchased a juvenile Borneo Short Tail about 10inches long and Ive never held a blood/short tail before so Q#1 - Is there skin supposed to be so easy to wrinkle up? or does that mean shes a bit skinny? Q#2 - I don't know if it's curiosity and her checking around but she seems to like to bend her head backwards/upside down a lot, and im paranoid about IBD.
