Yes,but it depends on what type of guineapigs they are.
yes
male+female= babies male+male = might fight female+female= might become friends
Not unless some form of artificial insemination is being used to impregnate them. Female guinea pigs cannot self-impregnate.
No. There must be a male and a female for the guinea pigs to have offspring.
Spayed
no because they are both female but they would fight if they wanted to make babies with a male.
No, they need to mate to have babies.
Not unless it is the father, take out the father 2 weeks before birth as the mother can become pregnant 2 hours after birth, this is fatal to the baby's and mother, the father may kill the baby's if left in same cage after birth. thank you hope i helped
A guinea pig will average around 3 or 4 babies in a litter, but the range can be 1-8! Good luck! :]
Yes, guinea pigs must mate to produce offspring.
