These are the first rats ive ever had in my care... They used to belong to my friend who moved to africa so i took them off his hands, they are about a year old and i know he never used to handle or play with them... When i first got them they were very timid and scared of me but i googled some techniques how to get them to bond with me... It was all going well and one even let me pick her up... But a couple of days later she bit me and seemed more scared than ever, now i am too scared to let them sniff my hand etc as all they both seem to want to do is bite me... It causes me great sadness that my rats might not be as happy as they could be... Has anybody got any suggestions as to what i could do, or at this point are they set in their ways forever and would the best thing just to take care of them as they are, as i dont want to cause them any unnecessary stress
