"Mrs S and Miss S have PMT" .... they usually managed it together .... fortunately Mrs S has now put all that behind her (or so it seems)
But that is normal when women live together.
Same with Chimpanzees I'm assured ...... in many ways. 
In WHAT many ways specifically are you referring the likeness to Mr. Snoops? Please elaborate and then I'll know whether to give you a cuddle or a slap 
Mutual grooming (Show me any group of girlies who do not comb one anothers hair, share each others mascara etc), Dominant Female reserving Alpha Male for herself and fighting off all comers, Refusal to have sex with more than one mate at a time then doing it with any other of the younger males of the troop the minute the Alpha's back is turned. Chattering between themselves to the exclusion of all else, Group toilet attendance. Squabbling at tea parties, Wearing things like banana leaves for hats .....OK?
I've watched and learned much from David Attenborough
