I would personally take them in, because if one day you decide to take them in, you might have 8 more guinea pigs !(because of the male being with the female)
It would also be better for them (even in the small cage) because you know the proper care. You can become their foster home ? You would take care of them, but also try to find a home for them. I understand if you can't take them in, because I couldn't either, even though I'd love to, but saddly I'm not 18 and still live with my parents which aren't animal people...
