I have one male (Lampo) guinea pig and 1 female (Ipin) but they are in different cages. Sometimes I let the male run around my room. One time i was letting my male piggy go out side and accident forgot to close Ipin's cage and she jumped out too. I don't remember how many minutes they was together. but now Ipin is in Pear shape,her belly is big and she eats a lot too. I just wonder she's pregnant or not >.< ? my father not gonna let they stay , what should I do after they born ?
