In my opinion as long as the big guy isn't leaving any marks or drawing blood then they are ok. My one male tends to rough house with my girls quite a bit more now that he is the only boy but the girls take care of them selves. On occassion I will hear more noise then usual and it sometimes is over who gets to sleep where. If they end up sleeping all in a bundle then I would venture to guess that they are ok. My male (Monkey) does seem to rile up my female (Lily) who has lymphoma more then the other girls, my only explaination is that he is trying to keep her active etc. Who knows why they do what they do.
