I'm writing you in response to your Craigslist posting for the three guinea pig babies you want to trade. I'm a guinea pig owner and I just wanted to make a couple of friendly suggestions to consider before releasing your pets into someone's care.
You may have already received offers for these adorable pups, and if so, please consider what kind of home they will be going to. Reptile owners often browse Craigslist looking for these kind of offers in order to get cheap food for snakes and other predators, and I'd hate to see them end up as a meal instead of a well loved and cared for member of someone's family. Parents and college students might also be contacting you about them, and while its possible they might have the space and ability to care for them, little children often quickly lose interest once babies stop being tiny and cute, and college students may find themselves too busy with school and commutes and the start of their lives to give a pet a good home.
If you've yet to recieve offers you are considering and are just looking to rehome your pets, you might consider calling the Stray Animal Adoption Program
in Newport, or the This Little Piggy & Me
guinea pig shelter in Cincinnati if that is closer. They will make sure your three babies get good homes and proper care.
I would take them myself, but I don't have room for all three. I've made a public post on a reputable pet forum to see if there are any local enthusiasts willing to team up to make sure your little ones get good homes, but there is no guarantee it will be successful.
It's possible that you've already thought of all this, and if so, great! Disregard my message and have a pleasant day. If not, please keep the shelters in mind if you don't receive offers from good quality pet owners who will take care of them their whole lives, instead of using them as feed or giving them up later due to human lifestyle constraints
