Yes. If guinea pigs are not healthy e.g they are too thin , they are sick , they have an infection , it is hard and unhealthy for them too have babies. It's not recommended and you really shouldn't, but it can be done.
Most can if they are old enough
No. There must be a male and a female for the guinea pigs to have offspring.
They can be pregnant but it is not fair for a baby guinea pig to have to hold up to 8 guinea pigs. There is a very high chance they will die. I had a guinea pig that was pregnant when I got her(she was 14 weeks when she had babies) and she had 2 babies and tey all survived.
Spayed
no because they are both female but they would fight if they wanted to make babies with a male.
A guinea pig will average around 3 or 4 babies in a litter, but the range can be 1-8! Good luck! :]
A full grown healthy guinea pig CAN swim but not babies or old ones.
Yes, guinea pigs must mate to produce offspring.
well in one go a female guinea pig can have 20 babies sbut the most i have seen n one go are 60
when they get fat u feal babies in it and they just lie there
I would not recommend it. Just have the Mother Guinea Pig in with her babies separately. Sometimes the other guinea pigs can get excited and accidentally stomp the babies to death so best to keep Mom & babies separate.
yes
