I have an elder sister and her younger brother (Indian palm squirrels,5weeks old,both opened eyes recently).ever since they opened eyes,the elder sister constantly spars with her brother whenever they are kept near to each other.both of them are since kept separate .they are occasionally put together to improve their bonding when I am with them,but have not showed any signs of improvement for a week now.will they ever reconcile or is it necessary that I should raise some separate?
