Hi! I'm new here. I have two older female guinea pigs (around 2 years) i used to have a third but she passed two weeks ago. Three days ago i got a female baby guinea pig thats around 7 weeks old. Ive been housing her in the upper level of their c&c cage for the past few days and I'm letting them meet eachother now. My baby guinea pig seems to think one of the older females is her mother? She keeps trying to suckle on her nipples which is aggravating my older pig and making her be mean . Does anyone know why shes doing this to my older pig and howto properly introduce them?
