keep them with a male.
Edit:
Only do this if you are prepared. Over a fifth of guinea pigs die from giving birth.
EDIT: put a mail in the cage, but onley for about 3 days... if he is still in there when the mother has her babbies he could get her pregnant again rite after she has the babbies, this would be verry stressfule on the mother , and could make her sick, or she could abandone her babbies. be redy for the babbies if you dont have a plan they could be hard to finde a good home for, you could alwayes decide to adopt one, there are meney loving guinie pigs alredy out there.
When I got my guinea pig, we didn't know she was pregnant, so about a month later, my sister got one that wasn't pregnant. It was a little less that a month after that that my guinea pig had 2 babies. During that time, though, Molly, the pregnant guinea pig, was acting very territorial, and Milly, the non pregnant guinea pig, was staying by herself and not having anything to do with Molly. So make sure that if you put a pregnant guinea pig with a non pregnant guinea pig, that the non pregnant guinea pig is a girl, or else there WILL be trouble.
No the guinea pig will no get pregnant.
Only the guinea pig she mated with but be sure to separate them after birth
A guinea pig can only get pregnant if a male guinea pig has humped it. A guinea pig may have fallen pregnant while it was in the pet shop or where ever you got it. Now if you think she is pregnant it is important to research breeding guinea pigs.
Keep them with a male guinea pig. Be careful because sometime the male with harrass the female.
No, only girls get pregnant :)
No, not posible.
The guinea pig will be heavier than usual.
Yes and fast
Yes, a veterinarian can perform an ultrasound or X-ray to confirm if a female guinea pig is pregnant. It is not possible to accurately diagnose pregnancy in guinea pigs through physical examination alone.
NO.
The same thing as if it was not pregnant!
