Male guinea pigs can succesfully imprenate a female guinea pig at (I believe)only 8 weeks of age, however it takes about 9 months for the guinea pig to be fully grown.
No. Male guinea pigs are sexually mature at around six months of age. o yes get closer
No they are very playful they will always not be to old to be your friend!
It shouldn't be by an age it should be how mature you are , but in my opinion if you are supervised you should be able to wash them at around 8 years of age.
The best age to breed your guinea-pigs is 5 months to a year old.
Female guinea pigs sexually mature very early. They can actually begin to reproduce at 3 to 4 weeks of age. Pregnancy is especially hard on a guinea pig, but even more so at this age. It is usually recommended that you do not allow your guinea pig to breed, but if you are going to, wait until they are at least 7 months of age to allow them in with a male.
between 6 and 10 months for a female, not particularly important 4 male
guinea pigs are born with fur unless the are skinny guinea pigs ( breeds with no hair)
They stop having babies at six monthes of age. after that, if the guinea pig get pregnant, babies cant be born which would kill the mother because a couple bones close after that age and babies cant come out.
No, guinea pigs need a male around in order to mate. What probably happened is your guinea pig was pregnant when you bought it. This is quite common since guinea pigs are hard to sex when they are young but can however, reproduce at a very young age.
Male guinea pigs have been known to make a female pregnant when they are only a month old. But usually the male becomes fertile and wants to breed around 3-6 months of age. If you are planning on breeding, I suggest not to because the risk that the female will die giving birth or that she will give birth to "lethals" (babies without eyes or have crooked teeth) is high.
yes they can guinea pigs can be trained any age but if you train them its best to start young!! : )
About 4 weeks of age.
