It took mine 6 months. They mated in the winter though in the summer it probably takes 4.
Yes, guinea pigs must mate to produce offspring.
No, they need to mate to have babies.
Yes, they will do this. You have to have a girl and a boy together to make any babies. It may be safe to keep the boys away from the girls.
They mate.
The earliest a guinea pig can mate is at the age of 6-8 weeks.
you cant make your guinea pigs mate, however if you leave them alone for long periods of time together they are more likely to. they may have already if they have spent time together and it could be early in the pregnancy when signs aren't as noticeable.
That would not be good. The babies would probably have some things genetically wrong with them, as having a father dog mate with his daughter.
Try to put them in a small cage together.
Female guinea pigs usually don't have babies until they are about 4 months old.
they make babies
No time at all. They do not really bond with other guinea pigs, so when their mate dies it does not affect them at all.
well guinea pigs will mate and make themselves but its really just called nature
