The best age to breed your guinea-pigs is 5 months to a year old.
Guinea pigs are afraid of vacuums for the first 4 or 5 times but after that they get used to the noise and they are not scared.
Females can get as big as male Guinea pigs which can be up to 2-5 pounds
Well, guinea pigs live up to 5-8 years
If you want 2 pigs, you have to get them at a young age together and they should preferably be two males as they are less prone to fighting. I've had 5 gp
Guinea pigs don't have to be a certain age but they should at least be a few months old. guinea pigs are strict vegetarians so they would like to eat vegetables like carrot's. My guinea loves carrots she can finish a whole in in 5 minutes!
Average life expectancy of a guinea pig is 4-8 years.
Guinea pigs live 3-8 years, but an average life span for healthy guinea pigs is about 5-6 years. A lucky guinea pig can sometimes live up to 10 years! So, a 5 year old guinea pig is getting up there in years, but if properly cared for, can live for a long awhile yet.
4-7 years. 5 is Normal
guinea pigs are pretty much fully grown once they are 5 months old
If you are asking how long they live, it can be up to 5 or if your guinea pig is very healthy 7 years. :)
