My younger sister got a sugar glider for her birthday and literally never held him(Seymour) and after a week of staying in his cage and never being touched, she was hospitalized for almost three full weeks. I fed him and gave him yogurt treats, but I didn't want him to bond to me, because he wasn't mine. When she got back home she asked if I wanted him. I obviously said yes, because I was the one who wanted one in the first place. Its been about three months since hes been officially mine and ive bonded with him every day for hours and hours and I still don't feel like hes bonded to me. I got him a larger cage about three days ago and put tons of toys in it and got him a wodent wheel(which he LOVES) but I feel that he isn't fully bonded to me. I put a shirt that I wear a lot in his cage for him to nest in and he loves it, but he wont let me pet him for very long before he trys to bite me. I feel like we are merely acquaintances and not life long companions like we should be. Am I doing something wrong, or is it jut going to take a while for him to fully trust me since he went almost a month without bonding to anyone? Im so worried. Please help):
