My son's new guinea pig unexpectedly had babies last night. They are very cute. Petsmart agreed to take them back when they are old enough to leave their mom but I would happily adopt them out to someone on this board that was looking for two cute little pigs for pets.
Not sure if you've already found them a home or not, but make sure if there are any male babies that they have been removed from mom by 21 days old or they will likely get her pregnant. They mature very quickly! Not sure how much you know about gp's, but a great resource for info is www.guinealynx.com. I had a few for years, they are fun critters
These little guys make great pets
I love Guinea Pigs, the babies are not like mice or rats, naked pinkies. They look like tiny adult Guinea Pigs that can eat solid food and run around. My Jack and Jill had 2 babies, the little boy looked just like Daddy, chestnut & white with a swirly coat and the little girl looked like Mommy, tri-colored smooth coated. I'm sure your son will enjoy the babies until they are old enough to go.
