I just wonder because I got Mr Bump and Asterixx when they were five weeks old. I looked after them for a year together then Mr Bump went to live with my Mum. I've just brought him over to my house again after about 9 months away from it to care for his sore neck as Mum cannot hold him to bathe him and he his violently fighting with the others that he used to live with. It's upsetting to see and my others are getting scared. Does he not remember them? Not even his brother?
